  • book titled Chernobyl: Consequences of the Catastrophe for People and the Environment in a publication called the Annals of the New York Academy of Sciences. The roots of the decision remain murky. Within a few months after the first printing of the book, Ted Rockwell, a long time member of the Academy, started working to convince NYAS leaders that the decision to print was a grave error that was bad for science and posed a significant risk to the reputation of the Academy as a source of sound, peer-reviewed information. As part of his effort, he encouraged the current editor of Annals of the New York Academy of Sciences to appoint reviewers and to post the results of those reviews.

Economic Aspects of Nuclear Fuel Reprocessing [12Jul05] - 0 views

  • On Tuesday, July 12, the Energy Subcommittee of the House Committee on Science will hold a hearing to examine whether it would be economical for the U.S. to reprocess spent nuclear fuel and what the potential cost implications are for the nuclear power industry and for the Federal Government. This hearing is a follow-up to the June 16 Energy Subcommittee hearing that examined the status of reprocessing technologies and the impact reprocessing would have on energy efficiency, nuclear waste management, and the potential for proliferation of weapons-grade nuclear materials.
  • Dr. Richard K. Lester is the Director of the Industrial Performance Center and a Professor of Nuclear Science and Engineering at the Massachusetts Institute of Technology. He co-authored a 2003 study entitled The Future of Nuclear Power. Dr. Donald W. Jones is Vice President of Marketing and Senior Economist at RCF Economic and Financial Consulting, Inc. in Chicago, Illinois. He co-directed a 2004 study entitled The Economic Future of Nuclear Power. Dr. Steve Fetter is the Dean of the School of Public Policy at the University of Maryland. He co-authored a 2005 paper entitled The Economics of Reprocessing vs. Direct Disposal of Spent Nuclear Fuel. Mr. Marvin Fertel is the Senior Vice President and Chief Nuclear Officer at the Nuclear Energy Institute.
  • 3. Overarching Questions  Under what conditions would reprocessing be economically competitive, compared to both nuclear power that does not include fuel reprocessing, and other sources of electric power? What major assumptions underlie these analyses?  What government subsidies might be necessary to introduce a more advanced nuclear fuel cycle (that includes reprocessing, recycling, and transmutation—''burning'' the most radioactive waste products in an advanced reactor) in the U.S.?

  • 4. Brief Overview of Nuclear Fuel Reprocessing (from June 16 hearing charter)  Nuclear reactors generate about 20 percent of the electricity used in the U.S. No new nuclear plants have been ordered in the U.S. since 1973, but there is renewed interest in nuclear energy both because it could reduce U.S. dependence on foreign oil and because it produces no greenhouse gas emissions.  One of the barriers to increased use of nuclear energy is concern about nuclear waste. Every nuclear power reactor produces approximately 20 tons of highly radioactive nuclear waste every year. Today, that waste is stored on-site at the nuclear reactors in water-filled cooling pools or, at some sites, after sufficient cooling, in dry casks above ground. About 50,000 metric tons of commercial spent fuel is being stored at 73 sites in 33 states. A recent report issued by the National Academy of Sciences concluded that this stored waste could be vulnerable to terrorist attacks.
  • Under the current plan for long-term disposal of nuclear waste, the waste from around the country would be moved to a permanent repository at Yucca Mountain in Nevada, which is now scheduled to open around 2012. The Yucca Mountain facility continues to be a subject of controversy. But even if it opened and functioned as planned, it would have only enough space to store the nuclear waste the U.S. is expected to generate by about 2010.  Consequently, there is growing interest in finding ways to reduce the quantity of nuclear waste. A number of other nations, most notably France and Japan, ''reprocess'' their nuclear waste. Reprocessing involves separating out the various components of nuclear waste so that a portion of the waste can be recycled and used again as nuclear fuel (instead of disposing of all of it). In addition to reducing the quantity of high-level nuclear waste, reprocessing makes it possible to use nuclear fuel more efficiently. With reprocessing, the same amount of nuclear fuel can generate more electricity because some components of it can be used as fuel more than once.
  • The greatest drawback of reprocessing is that current reprocessing technologies produce weapons-grade plutonium (which is one of the components of the spent fuel). Any activity that increases the availability of plutonium increases the risk of nuclear weapons proliferation.  Because of proliferation concerns, the U.S. decided in the 1970s not to engage in reprocessing. (The policy decision was reversed the following decade, but the U.S. still did not move toward reprocessing.) But the Department of Energy (DOE) has continued to fund research and development (R&D) on nuclear reprocessing technologies, including new technologies that their proponents claim would reduce the risk of proliferation from reprocessing.
  • The report accompanying H.R. 2419, the Energy and Water Development Appropriations Act for Fiscal Year 2006, which the House passed in May, directed DOE to focus research in its Advanced Fuel Cycle Initiative program on improving nuclear reprocessing technologies. The report went on to state, ''The Department shall accelerate this research in order to make a specific technology recommendation, not later than the end of fiscal year 2007, to the President and Congress on a particular reprocessing technology that should be implemented in the United States. In addition, the Department shall prepare an integrated spent fuel recycling plan for implementation beginning in fiscal year 2007, including recommendation of an advanced reprocessing technology and a competitive process to select one or more sites to develop integrated spent fuel recycling facilities.''
  • During floor debate on H.R. 2419, the House defeated an amendment that would have cut funding for research on reprocessing. In arguing for the amendment, its sponsor, Mr. Markey, explicitly raised the risks of weapons proliferation. Specifically, the amendment would have cut funding for reprocessing activities and interim storage programs by $15.5 million and shifted the funds to energy efficiency activities, effectively repudiating the report language. The amendment was defeated by a vote of 110–312.
  • But nuclear reprocessing remains controversial, even within the scientific community. In May 2005, the American Physical Society (APS) Panel on Public Affairs, issued a report, Nuclear Power and Proliferation Resistance: Securing Benefits, Limiting Risk. APS, which is the leading organization of the Nation's physicists, is on record as strongly supporting nuclear power. But the APS report takes the opposite tack of the Appropriations report, stating, ''There is no urgent need for the U.S. to initiate reprocessing or to develop additional national repositories. DOE programs should be aligned accordingly: shift the Advanced Fuel Cycle Initiative R&D away from an objective of laying the basis for a near-term reprocessing decision; increase support for proliferation-resistance R&D and technical support for institutional measures for the entire fuel cycle.''  Technological as well as policy questions remain regarding reprocessing. It is not clear whether the new reprocessing technologies that DOE is funding will be developed sufficiently by 2007 to allow the U.S. to select a technology to pursue. There is also debate about the extent to which new technologies can truly reduce the risks of proliferation.
  •  It is also unclear how selecting a reprocessing technology might relate to other pending technology decisions regarding nuclear energy. For example, the U.S. is in the midst of developing new designs for nuclear reactors under DOE's Generation IV program. Some of the potential new reactors would produce types of nuclear waste that could not be reprocessed using some of the technologies now being developed with DOE funding.
  • 5. Brief Overview of Economics of Reprocessing
  • The economics of reprocessing are hard to predict with any certainty because there are few examples around the world on which economists might base a generalized model.  Some of the major factors influencing the economic competitiveness of reprocessing are: the availability and cost of uranium, costs associated with interim storage and long-term disposal in a geologic repository, reprocessing plant construction and operating costs, and costs associated with transmutation, the process by which certain parts of the spent fuel are actively reduced in toxicity to address long-term waste management.
  • Costs associated with reducing greenhouse gas emissions from fossil fuel-powered plants could help make nuclear power, including reprocessing, economically competitive with other sources of electricity in a free market.
  •  It is not clear who would pay for reprocessing in the U.S.
  • Three recent studies have examined the economics of nuclear power. In a study completed at the Massachusetts Institute of Technology in 2003, The Future of Nuclear Power, an interdisciplinary panel, including Professor Richard Lester, looked at all aspects of nuclear power from waste management to economics to public perception. In a study requested by the Department of Energy and conducted at the University of Chicago in 2004, The Economic Future of Nuclear Power, economist Dr. Donald Jones and his colleague compared costs of future nuclear power to other sources, and briefly looked at the incremental costs of an advanced fuel cycle. In a 2003 study conducted by a panel including Matthew Bunn (a witness at the June 16 hearing) and Professor Steve Fetter, The Economics of Reprocessing vs. Direct Disposal of Spent Nuclear Fuel, the authors took a detailed look at the costs associated with an advanced fuel cycle. All three studies seem more or less to agree on cost estimates: the incremental cost of nuclear electricity to the consumer, with reprocessing, could be modest—on the order of 1–2 mills/kWh (0.1–0.2 cents per kilowatt-hour); on the other hand, this increase represents an approximate doubling (at least) of the costs attributable to spent fuel management, compared to the current fuel cycle (no reprocessing). Where they strongly disagree is on how large an impact this incremental cost will have on the competitiveness of nuclear power. The University of Chicago authors conclude that the cost of reprocessing is negligible in the big picture, where capital costs of new plants dominate all economic analyses. The other two studies take a more skeptical view—because new nuclear power would already be facing tough competition in the current market, any additional cost would further hinder the nuclear power industry, or become an unacceptable and unnecessary financial burden on the government.

Citizens' forum queries nuclear 'experts' [23Oct11] - 0 views

  • To whom does scientific debate belong? That was a central question raised by many of the 200-plus people who attended a citizens' forum in Tokyo on Oct. 12, as they criticized the ways in which the Japanese government and radiation specialists working for it are assessing and monitoring the health effects of the ongoing nuclear disaster at the Fukushima No. 1 nuclear power plant. The daylong conference, organized by the Japanese citizens' groups SAY-Peace Project and Citizens' Radioactivity Measuring Station (CRMS), featured experts who dispute much of the evidence on which the government has based its health and welfare decisions affecting residents of Fukushima Prefecture and beyond. Organizers of the event were also demanding that the government take into consideration the views of non-experts — and also experts with differing views from those of official bodies such as the International Commission on Radiological Protection (ICRP). The Japanese government has constantly referred to the ICRP's recommendations in setting radiation exposure limits for Fukushima residents.
  • One of the driving forces for the citizens' forum was a desire to challenge the conduct and much of the content of a conference held Sept. 11-12 in Fukushima, titled the "International Expert Symposium in Fukushima — Radiation and Health Risk." That conference, sponsored by the Nippon Foundation, involved some 30 scientists from major institutions, including the ICRP, the World Health Organization, the International Atomic Energy Agency and the United Nations Scientific Committee on the Effects of Atomic Radiation. Although the proceedings were broadcast live on U-stream, the event itself was — unlike the Tokyo forum — closed to the public. Some citizens and citizens' groups claimed that this exclusion of many interested and involved parties — and the event's avowed aim of disseminating to the public "authoritative" information on the health effects of radiation exposure — ran counter to the pursuit of facilitating open and free exchanges among and between experts and citizens on the many contentious issues facing the nation and its people at this critical time.
  • In particular, there was widespread criticism after the Fukushima conference — which was organized by Shunichi Yamashita, the vice president of Fukushima Medical University and a "radiological health safety risk management advisor" for Fukushima prefectural government — that its participants assumed from the outset that radioactive contamination from the plant's wrecked nuclear reactors is minimal. Critics also claimed that the experts invited to the conference had turned a collective blind eye to research findings compiled by independent scientists in Europe in the aftermath of the 1986 Chernobyl nuclear disaster in present-day Ukraine — specifically to findings that point to various damaging health consequences of long-term exposure to low-level radiation. So it was that those two citizens' groups, angered by these and other official responses to the calamity, organized the Oct. 12 conference held at the National Olympics Memorial Youth Center in Shibuya Ward. Among the non-experts and experts invited to attend and exchange their views were people from a wide range of disciplines, including sociology, constitutional law and pediatrics. On the day, some of the speakers took issue with the stance of the majority of official bodies that the health damage from Chernobyl was observed only in a rise in the number of cases of thyroid cancers.

  • Eisuke Matsui, a lung cancer specialist who is a former associate professor at Gifu University's School of Medicine, argued in his papers submitted to the conference that the victims of Chernobyl in the neighboring present-day country of Belarus have suffered from a raft of other problems, including congenital malformations, type-1 diabetes and cataracts. Matsui cited a lengthy and detailed report of research by the Russian scientists Alexey V. Yablokov, Vassily B. Nesterenko and Alexey V. Nesterenko that was published in 2007, and republished in English in 2009 by the New York Academy of Sciences under the title "Chernobyl: Consequences of the Catastrophe for People and the Environment." Matsui stressed that, based on such evidence, the Japanese government should approve group evacuations of children — at the expense of the plant's operator, Tokyo Electric Power Co. — from certain parts of Fukushima Prefecture. He cited some areas of the city of Koriyama, 50 to 60 km from the stricken nuclear plant, where soil contamination by radioactive cesium-137 has reached 5.13 Curies per sq. km. That is the same as in areas of Ukraine where residents were given rights to evacuate, Matsui said. In fact in June, the parents of 14 schoolchildren in Koriyama filed a request for a temporary injunction with the Fukushima District Court, asking it to order the city to send their children to schools in safer areas.
  • In the ongoing civil suit, those parents claim that the children's external radiation exposure has already exceeded 1 millisievert according to official data — the upper yearly limit from all sources recommended by the ICRP for members of the public under normal conditions. Following a nuclear incident, however, the ICRP recommends local authorities to set the yearly radiation exposure limit for residents in contaminated areas at between 1 and 20 millisieverts, with the long-term goal of reducing the limit to 1 millisievert per year. Meanwhile, Hisako Sakiyama, former head researcher at the National Institute of Radiological Sciences, delved into the non-cancer risks of exposure to radiation. In her presentation, she referred to a report compiled in April by the German Affiliate of International Physicians for the Prevention of Nuclear War (IPPNW). Titled "Health Effects of Chernobyl: 25 years after the reactor catastrophe," this documents an alarmingly high incidence of genetic and teratogenic (fetal malformation) damage observed in many European countries since Chernobyl.
  • Sakiyama also pointed out that the German report showed that the incidence of thyroid cancer due to radiation exposure was not limited to children. For instance, she cited IPPNW survey findings from the Gomel district in Belarus, a highly-contaminated area, when researchers compared the incidence of thyroid cancer in the 13 years before the Chernobyl explosion and the 13 years after. These findings show that the figures for the latter period were 58 times higher for residents aged 0-18, 5.3 times higher for those aged 19-34, 6 times higher for those aged 35-49, and 5 times higher for those aged 50-64. "In Japan, the government has a policy of not giving out emergency iodine pills to those aged 45 and older (because it considers that the risk of them getting cancer is very low),"' Sakiyama said. "But the (IPPNW) data show that, while less sensitive compared to children, adults' risks go up in correspondence with their exposure to radioactivity."
  • Further post-Chernobyl data was presented to the conference by Sebastian Pflugbeil, a physicist who is president of the German Society for Radiation Protection. Reporting the results of his independent research into child cancers following the Chernobyl disaster, he said that "in West Germany ... with an exposure of 1 millisievert per year, hundreds of thousands of children were affected." He noted, though, that any official admissions regarding health damage caused by the 1986 disaster in the then Soviet Union came very slowly and insufficiently in Europe. Indeed, he said the authorities denied there were health risks for years afterward. In response, an audience member who said he was a science teacher at a junior high school in Kawaguchi, Saitama Prefecture, asked Pflugbeil to exactly identify the level of exposure beyond which residents should be evacuated. While acknowledging that was a very difficult question, the German specialist noted later, however, that he would think pregnant women should probably leave Fukushima — adding, "I have seen many cases over the years, but I come from Germany and it's not easy to judge (about the situation in Japan)."
  • At a round table discussion later in the day, as well as discussing specific issues many participants made the point that science belongs to the people, not just experts — the very point that underpinned the entire event. As Wataru Iwata, director of the Fukushima-based citizens' group CRMS, one of the forum's organizers (which also conducts independent testing of food from in and around Fukushima Prefecture) put it: "Science is a methodology and not an end itself." In the end, though the citizens' forum — which ran from 9:30 a.m. to 10 p.m. — arrived at no clear-cut conclusions, organizers said that that in itself was a good outcome. And another conference involving citizens and scientists is now being planned for March 2012.

Ministry of Education orders false dosimeters [27Nov11] - 0 views

  • Since 311, Japanese government pretended to check radiation level of various areas in Japan, but because they measure radiation at 14 m or 85 m high from the ground, nobody got to believe the data. They therefore ordered 600 dosimeters from a Geiger counter maker named Alpha Tsushin. Those dosimeters were supposed to be put at schools in Fukushima etc.. However, the Ministry of Education, Culture, Sports, Science and Technology stated they cancelled the contract on 11/18/2011 because “their dosimeter is not accurate and they can’t make 600 of the dosimeters by the deadline.”
  • However, according to the explanation of Alpha Tsushin, it was because the Ministry of Education, Culture, Sports, Science and Technology wanted false dosimeter. The Ministry of Education, Culture, Sports, Science and Technology was afraid to show higher radiation levels than the monitoring posts set on 14 m or 85 m high from the ground, so they ordered Alpha Tsushin to make geiger counters to indicate lower radiation level than actual. Alpha Tsushin uses parts from America, which are manufactured using international standards, but the Ministry of Education, Culture, Sports, Science and Technology tried to force the engineers to use the “Japanese standard”. As a result, Alpha Tsushin was cancelled, luckily for them.
  • The company is planning to have a press conference to tell the truth.

Cesium from Fukushima plant fell all over Japan [26Nov11] - 0 views

  • Radioactive substances from the crippled Fukushima No. 1 nuclear power plant have now been confirmed in all prefectures, including Uruma, Okinawa Prefecture, about 1,700 kilometers from the plant, according to the science ministry. The ministry said it concluded the radioactive substances came from the stricken nuclear plant because, in all cases, they contained cesium-134, which has short half-life of two years. Before the March 11 Great East Japan Earthquake, radioactive substance were barely detectable in most areas.
  • the Ministry of Education, Culture, Sports, Science and Technology's survey results released on Nov. 25 showed that fallout from the Fukushima plant has spread across Japan. The survey covered the cumulative densities of radioactive substances in dust that fell into receptacles during the four months from March through June. Figures were not available for Miyagi and Fukushima prefectures, where the measurement equipment was rendered inoperable by the March 11 disaster. One measurement station was used for each of the other 45 prefectures. The highest combined cumulative density of radioactive cesium-134 and cesium-137 was found in Hitachinaka, Ibaraki Prefecture, at 40,801 becquerels per square meter. That was followed by 22,570 becquerels per square meter in Yamagata, the capital of Yamagata Prefecture, and 17,354 becquerels per square meter in Tokyo's Shinjuku Ward.
  • The current air radiation level in Ibaraki Prefecture is about 0.14 microsievert per hour, equivalent to an annual dose of about 1 millisievert, the safety limit for exposure under normal time international standards. Large amounts of radioactive dust fell in Tokyo, but a separate survey has detected relatively low accumulations of cesium in the soil. "Tokyo has smaller soil surfaces than other prefectures, but road and concrete surfaces are less prone to fixate cesium deposits, which were probably diffused by the wind and rain," a ministry official explained.
  • ...2 more annotations...
  • The fallout densities were considerably lower in the Chugoku and Kyushu regions in western Japan. The smallest figure of 0.378 becquerel per square meter came from Uto, Kumamoto Prefecture. The density in Osaka was 18.9 becquerels per square meter. The peak value in Ibaraki Prefecture was 970,000 times larger than the cumulative fallout density of 0.042 becquerel per square meter in fiscal 2009, found in an earlier nationwide survey before the Fukushima crisis started.
  • Also on Nov. 25, the science ministry released maps of aerially measured radioactive cesium from the Fukushima plant that accumulated in Aomori, Ishikawa, Fukui and Aichi prefectures. This was the final batch of the 22 prefectures in eastern Japan where mapping was to be completed by the end of this year. Nowhere in the four prefectures did the accumulations exceed 10,000 becquerels per square meter, the threshold for defining an area as being affected by the nuclear accident. This reconfirmed the science ministry's view that radioactive plumes wafted only as far west as the border of Gunma and Nagano prefectures and as far north as the border of Miyagi and Iwate prefectures, ministry officials said.

Tritium leaks hit three-quarters of U.S. nuclear plants [27Jun11] - 1 views

  • Radioactive tritium has leaked from three-quarters of U.S. commercial nuclear power sites, often into groundwater from corroded, buried piping, an Associated Press investigation shows.
  • The number and severity of the leaks has been escalating, even as federal regulators extend the licenses of more and more reactors across America. Tritium, which is a radioactive form of hydrogen, has leaked from at least 48 of 65 sites, according to U.S. Nuclear Regulatory Commission records reviewed as part of the AP's yearlong examination of safety issues at aging nuclear power plants. Leaks from at least 37 of those facilities contained concentrations exceeding the federal drinking water standard — sometimes at hundreds of times the limit.
  • While most leaks have been found within plant boundaries, some have migrated offsite. But none is known to have reached public water supplies. STORY: Regulators weaken safety standards for nuclear reactors At three sites — two in Illinois and one in Minnesota — leaks have contaminated drinking wells of nearby homes, the records show, but not at levels violating the drinking water standard. At a fourth site, in New Jersey, tritium has leaked into an aquifer and a discharge canal feeding picturesque Barnegat Bay off the Atlantic Ocean.
  • ...7 more annotations...
  • Any exposure to radioactivity, no matter how slight, boosts cancer risk, according to the National Academy of Sciences. Federal regulators set a limit for how much tritium is allowed in drinking water, where this contaminant poses its main health risk. The U.S. Environmental Protection Agency says tritium should measure no more than 20,000 picocuries per liter in drinking water. The agency estimates seven of 200,000 people who drink such water for decades would develop cancer.
  • The tritium leaks also have spurred doubts among independent engineers about the reliability of emergency safety systems at the 104 nuclear reactors situated on the 65 sites. That's partly because some of the leaky underground pipes carry water meant to cool a reactor in an emergency shutdown and to prevent a meltdown. Fast moving, tritium can indicate the presence of more powerful radioactive isotopes, like cesium-137 and strontium-90.
  • So far, federal and industry officials say, the tritium leaks pose no health or safety threat. Tony Pietrangelo, chief nuclear officer of the industry's Nuclear Energy Institute, said impacts are "next to zero." LEAKS ARE PROLIFIC
  • Like rust under a car, corrosion has propagated for decades along the hard-to-reach, wet underbellies of the reactors — generally built in a burst of construction during the 1960s and 1970s. There were 38 leaks from underground piping between 2000 and 2009, according to an industry document presented at a tritium conference. Nearly two-thirds of the leaks were reported over the latest five years
  • For example, at the three-unit Browns Ferry complex in Alabama, a valve was mistakenly left open in a storage tank during modifications over the years. When the tank was filled in April 2010, about 1,000 gallons (3,785 liters) of tritium-laden water poured onto the ground at a concentration of 2 million picocuries per liter. In drinking water, that would be 100 times higher than the EPA health standard. And in 2008, 7.5 million picocuries per liter leaked from underground piping at Quad Cities in western Illinois — 375 times the EPA limit.
  • Subsurface water not only rusts underground pipes, it attacks other buried components, including electrical cables that carry signals to control operations. A 2008 NRC staff memo reported industry data showing 83 failed cables between 21 and 30 years of service - but only 40 within their first 10 years of service. Underground cabling set in concrete can be extraordinarily difficult to replace.
  • Under NRC rules, tiny concentrations of tritium and other contaminants are routinely released in monitored increments from nuclear plants; leaks from corroded pipes are not permitted. The leaks sometimes go undiscovered for years, the AP found. Many of the pipes or tanks have been patched, and contaminated soil and water have been removed in some places. But leaks are often discovered later from other nearby piping, tanks or vaults. Mistakes and defective material have contributed to some leaks. However, corrosion - from decades of use and deterioration - is the main cause. And, safety engineers say, the rash of leaks suggest nuclear operators are hard put to maintain the decades-old systems.

Short-Termism and Energy Revolutions [30Sep11] - 0 views

  • The calls these days for a technological “energy revolution” are widespread. But how do you spark breakthroughs when the natural bias of businesses, investors and governments is toward the here and now? In governance, politics creates a bias toward the short term. This is why bridges sometimes fall down for lack of maintenance. That’s also why it’s so hard to sustain public investment in the research and intellectual infrastructure required to make progress on the frontiers of chemistry, biology and physics, even though it is this kind of work that could produce leaps in how we harvest, harness, store and move energy. (This is why I asked, “Are Chemists and Engineers on the Green Jobs List?” back in 2008.)
  • To get the idea, you only have to look at the sputtering state of President Obama’s mostly unfunded innovation hubs, or look once again at the energy sliver in the graph showing America’s half-century history of public investment in basic scientific research. (There’s not much difference in research patterns in most other industrialized countries.) You can also look at the first Quadrennial Technology Review produced by the Department of Energy (summarized by Climate Progress earlier this week). The review was conducted after the President’s Council of Advisers on Science and Technology wisely recommended regular reviews of this sort as part of its prescription for accelerating change in energy technologies.
  • This excerpt from the new review articulates the tension pretty transparently for a government report: There is a tension between supporting work that industry doesn’t— which biases the department’s portfolio toward the long term—and the urgency of the nation’s energy challenges. The appropriate balance requires the department to focus on accelerating innovation relevant to today’s energy technologies, since such evolutionary advances are more likely to have near- to mid-term impact on the nation’s challenges. We found that too much effort in the department is devoted to research on technologies that are multiple generations away from practical use at the expense of analyses, modeling and simulation, or other highly relevant fundamental engineering research activities that could influence the private sector in the nearer term.
  • ...16 more annotations...
  • In finding that balance, I’m not sure it’s possible to overcome the political pressures tugging agencies and officials to stress refinement and deployment of known and maturing technologies (even though that’s where industry and private investors are most focused).
  • On the left, the pressure is for resources to deploy today’s “green” technology. On the right, as illustrated in a Heritage Foundation report on ways to cut President Obama’s budget for the Energy Department, the philosophy seems to be to discourage all government spending on basic inquiry related to energy.
  • According to Heritage, science “in service of a critical national interest that is not being met by the private sector” is fine if that interest is national defense, but not fine if it’s finding secure and sustainable (environmentally and economically) sources of energy.
  • I solicited reactions to the Energy Department review from a variety of technology and innovation analysts. The first to weigh in are Daniel M. Kammen, an energy technology researcher at the University of California, Berkeley, who is on leave working for the World Bank, and Robert D Atkinson, the founder and president of the Information Technology and Innovation Foundation. Here’s Kammen: The idea of a regular review and status report on both energy innovation and deployment spending is a good one. Some of the findings in the QTR review are useful, although little is new. Overall, though, this is a useful exercise, and one that should be a requirement from any major programmatic effort.
  • he real need in the R&D sector is continuity and matching an increasing portfolio of strategic research with market expansion. My former student and colleague Greg Nemet have written consistently on this: - U.S. energy research and development: Declining investment, increasing need, and the feasibility of expansion - Reversing the Incredible Shrinking Energy R&D Budget
  • Perhaps the biggest worry in this report, however, is the missing logic and value of a ’shift to near term priorities in energy efficiency and in electric vehicles.’ This may be a useful deployment of some resources, but a range of questions are simply never addressed. Among the questions that need firmer answers are:
  • There are some very curious omissions from the report, such as more detail on the need to both generate and report on jobs created in this sector — a political ‘must’ these days (see, e.g., the “green jobs” review by the Renewable and Appropriate Energy Laboratory at Berkeley) — and straightforward comparisons in the way of ‘report cards’ on how the US is stacking up relative to other key players (e.g. China, Germany…).
  • given the state-by-state laboratories we already have of differing approaches to energy efficiency, the logic of spending in this area remains to be proven (as much as we all rightly love and value and benefit from energy efficiency).
  • Near-term electric vehicle deployment. A similar story could be told here. As the director of the University of California at Berkeley’s Transportation Sustainability Research Center (http://tsrc.berkeley.edu) I am huge believer in electric vehicles [EVs]. However, the review does not make clear what advances in this area are already supported through [the Advanced Research Projects Agency for Energy], and what areas of near-term research are also not best driven though regulation, such as low-carbon fuel standards, R&D tax credits, ‘feebates’ that transfer funds from those individuals who purchase inefficient vehicles to those who purchase efficient ones. Similar to the story in energy efficiency, we do have already an important set of state-by-state experiments that have been in place for some time, and these warrant an assessment of how much innovation they have driven, and which ones do and do not have an application in scale-up at the federal level.
  • Finally, the electric vehicle landscape is already very rich in terms of plans for deployment by automakers. What are the barriers five-plus years out that the companies see research-versus-deployment and market-expansion support as the most effective way to drive change in the industry? Where will this focus put the U.S. industry relative to China?
  • Following record levels funding made available to the energy industry through the [stimulus package of spending], what are the clearly identified market failures that exist in this area that added funding will solve? Funding is always welcome, but energy efficiency in particular, can be strongly driven by regulation and standards, and because good energy efficiency innovations have such rapid payback times, would regulatory approaches, or state-federal partnerships in regulation and incentives not accomplish a great deal of what can be done in this area? Congressman Holt raises a number of key questions on related issues, while pointing to some very hopeful experiences, notably in the Apollo program, in his 16 September editorial in Science.
  • Here’s Robert Atkinson: If DOE is shifting toward a more short-term focus, this is quite disturbing.  It would mean that DOE has given up on addressing the challenge of climate change and instead is just focused on the near term goal of reducing oil imports and modestly reducing the expansion the coal fired power plants. If DOE thinks it is still focused on climate change, do they think they are fighting “American warming”?
  • If so, cutting the growth of our emissions make sense.  But its global warming and solving this means supporting the development of scalable, cheap low or no-carbon energy so that every country, rich and poor, will have an economic incentive to transitioning to cheap energy.  Increasing building efficiency, modernizing the electric grid, alternative hydrocarbon fuels, and increasing vehicle efficiency do virtually nothing to meet this goal. They are “American warming” solutions.
  • This is also troubling because (as you point out) who else is going to invest in the long-term, more fundamental, high risk, breakthrough research than the U.S. government.  It certainly won’t be VCs. And it won’t be the Chinese who are principally interested in cutting their energy imports and exporting current generation clean energy, not developing technology to save the planet.  Of course all the folks out there who have been pushing the mistaken view that we have all the clean technologies we need, will hail this as the right direction.  But it’s doing what the rest of the market has been doing in recent years – shifting from high risk, long-term research to short-term, low risk.  If the federal government is doing this it is troubling to say the least.

Chris Huhne: Nuclear power a costly failure [15Oct11] - 0 views

  • Britain is still paying for nuclear-generated electricity consumed a generation ago because of the hidden costs of an industry reared on the expectation of public subsidies, the Energy Secretary Chris Huhne said yesterday. He told the Royal Society in London that the nuclear industry and the Government should show that they have learned from their past mistakes if they are to retain public support for a renaissance in nuclear power. “And some of those mistakes are not small,” he said in a keynote address. “Nuclear policy is a runner to be the most expensive failure of post-war British policy-making, and I am aware that this is a crowded and highly contested field.” http://www.independent.co.uk/news/science/chris-huhne-nuclear-power-a-costly-failure-2370340.html

Citizens' conference on radiation [23Oct11] - 0 views

shared by D'coda Dcoda on 23 Oct 11 - No Cached
  • Japan Times reports on a “Citizens’ conference” on radiation here. This was a gathering of people not qualified in any way with the purpose of spreading fear. I am pleased to read about it, since it gives me another great occasion to link to Rod Adams’ essential “Atomic Insights” blog. One of the “experts” speaking at the conference cited the Yablokow report on Chernobyl. Anybody who wants to assess the credibility of said report needs to read the review of by M.I. Balonow of the Institute of Radiation Hygiene, St. Petersburg, published in full at Atomic Insights.
  • That review states that the Yablokow report is “science fiction rather than science”. I recall blogging about how this pamphlet managed to be included in a formerly respected Journal published by the New York Academy of Sciences without peer review. The conference also had one Sebastian Pflugbeil as a speaker. His Wikipedia page shows that he is famous as a former East German politician, with no publications in the relevant field of radiation protection. His qualification as “president of the German Society of Radiation Protection” is rather less impressive once you realize that anyone is free to found this kind of society and call it “German Society of Radiation Protection”. According to the German Wikipedia page, this “German Society” was founded in 1990 and has about 50 members. When asked about what dose rate would justify an evacuation in his opinion, Pflugbeil answered that he does not know, since he only is informed about the effects of radiation in Germany. That answer does not exactly inspire confidence that he knows what he is talking about.
  • Another conference involving citizens and scientists is planned for next year. I am looking forward already to the opportunity to point againt to the above review of the Yablokow science fiction.

Bloomberg: Vindicated Seismologist Says Japan Still Underestimates Threat to Reactors [... - 0 views

  • Dismissed as a “nobody” by Japan’s nuclear industry, seismologist Katsuhiko Ishibashi spent two decades watching his predictions of disaster come true: First in the 1995 Kobe earthquake and then at Fukushima. He says the government still doesn’t get it.The 67-year-old scientist recalled in an interview how his boss marched him to the Construction Ministry to apologize for writing a 1994 book suggesting Japan’s building codes put its cities at risk. Five months later, thousands were killed when a quake devastated Kobe city. The book, “A Seismologist Warns,” became a bestseller.That didn’t stop Haruki Madarame, now head of Japan’s Nuclear Safety Commission, from dismissing Ishibashi as an amateur when he warned of a “nuclear earthquake disaster,” a phrase the Kobe University professor coined in 1997. Ishibashi says Japan still underestimates the risk of operating reactors in a country that has about 10 percent of the world’s quakes.
  • “What was missing -- and is still missing -- is a recognition of the danger,” Ishibashi said, seated in a dining room stacked with books in his house in a Kobe suburb. “I understand we’re not going to shut all of the nuclear plants, but we should rank them by risk and phase out the worst.”Among Japan’s most vulnerable reactors are some of its oldest, built without the insights of modern earthquake science, Ishibashi said. It was only in the last four years that Japan Atomic Power Co. recognized an active fault line running under its reactor in Tsuruga, which opened in 1970 about 120 kilometers (75 miles) northeast of Osaka and close to a lake that supplies water to millions of people in the region.New Fault LinesJapan Atomic is reinforcing the plant to improve quake tolerance and believes it’s safe despite the discovery of new active faults lines in 2008, Masao Urakami, a Tokyo-based spokesman for the utility, said.“We can’t respond to every claim by every scientist,” he said. “Standards for seismic ground motion are not decided arbitrarily, but are based on findings by experts assigned by the government.”
  • Reactor 1 at the Tsuruga plant, which had its license extended for 10 years in 2009, is one of 13 on Wakasa bay, a stretch of Sea of Japan coast that is home to the world’s heaviest concentration of nuclear reactors. The area is riddled with fault lines found in the last three or four years, according to Ishibashi.

  • His view changed after a magnitude-6.9 quake killed more than 5,500 people on Jan. 17, 1995, and toppled sections of elevated expressway.After a disaster that Japanese engineers had said couldn’t happen, the nuclear regulator didn’t immediately re-evaluate its construction standards. It said the plants were “safe from the ground up,” as the title of a 1995 Science Ministry pamphlet put it. Ishibashi decided to investigate.The result was an article on Hamaoka published in the October 1997 issue of Japan’s Science Journal that reads like a post-mortem of the Fukushima disaster: A major quake could knock out external power to the plant’s reactors and unleash a tsunami that could overrun its 6-meter defenses, swamping backup diesel generators and leading to loss of cooling and meltdowns.
  • Ishibashi a ‘Nobody’“In the field of nuclear engineering, Mr. Ishibashi is a nobody,” Madarame said in a 1997 letter to the Shizuoka Legislature. Madarame, then a professor at the University of Tokyo school of engineering, is now in charge of nuclear safety in the country.

Unexpected Clue to Thermopower Efficiency: Uneven Temperature Can Lead to Electronic Wh... - 0 views

  • Berkeley Lab scientists and their colleagues have discovered a new relation among electric and magnetic fields and differences in temperature, which may lead to more efficient thermoelectric devices that convert heat into electricity or electricity into heat.
  • An n-type semiconductor on top of a p-type semiconductor creates a vertical electric field (E, green arrow), while diffusion creates a depletion layer near the junction (orange), where the electric field is strongest. Heating one end of the device creates a heat gradient at right angles to the electric field (del T, red arrow). Electrons and holes moving in these fields are forced into loops of current, and a magnetic field is generated “sideways” (B, blue arrow), at right angles to both electric and thermal fields.
  • "In the search for new sources of energy, thermopower -- the ability to convert temperature differences directly into electricity without wasteful intervening steps -- is tremendously promising," says Junqiao Wu of Berkeley Lab's Materials Sciences Division (MSD), who led the research team. Wu is also a professor of materials science and engineering at the University of California at Berkeley. "But the new effect we've discovered has been overlooked by the thermopower community, and can greatly affect the efficiency of thermopower and other devices."

  • August 2, 2011 at 9:39 am I don’t see anything that looks like Liquid Air in the video, but I do see what appears to me to be the Shared Spent Fuel Pool on fire and with open criticality – which is more shocking than anything I’ve ever witnessed. 
  • ...6 more annotations...
  • The first day we heard about the possibility of open criticality at Fukushima, a week or so after the Earthquake in March- I was shocked. It didn’t even register that this was possible. Now, it’s a regular occurrence to see it openly on these videos. (again – look for the gamma artifacts on the video – little white flashes that appear randomly on the screen) Five months ago everyone in the nuclear industry would have said what this video depicts is impossible and should be avoided at all human costs – and yet here we see it. 
  • Most of them are still unwilling to admit that it’s happening, yet it has. The jig is up, the noose is out….
  • f you need a definition of ‘criticality’ here it is (from BBC) This means the fuel rods are exposed to the air. Without water, they will get much hotter, allowing radioactive material to escape.
  • More remarkably, the Tokyo Electric Power Company (Tepco), which owns the power station, has warned: “The possibility of re-criticality is not zero“. If you are in any doubt as to what this means, it is that in the company’s view, it is possible that enough fissile uranium is present in the cooling pond in enough density to form a critical mass – meaning that a nuclear fission chain reaction could start.
  • The pool lies outside the containment chamber.  So if it happened, it would lead to the enhanced and sustained release of radioactive materials – though not to a nuclear explosion – with nothing to stop the radioactive particles escaping.  http://www.bbc.co.uk/news/science-environment-12762608

Fukushima radiation alarms doctors [18Aug11] - 0 views

  • Scientists and doctors are calling for a new national policy in Japan that mandates the testing of food, soil, water, and the air for radioactivity still being emitted from Fukushima's heavily damaged Daiichi nuclear power plant."How much radioactive materials have been released from the plant?" asked Dr Tatsuhiko Kodama, a professor at the Research Centre for Advanced Science and Technology and Director of the University of Tokyo's Radioisotope Centre, in a July 27 speech to the Committee of Health, Labour and Welfare at Japan's House of Representatives. "The government and TEPCO have not reported the total amount of the released radioactivity yet," said Kodama, who believes things are far worse than even the recent detection of extremely high radiation levels at the plant. There is widespread concern in Japan about a general lack of government monitoring for radiation, which has caused people to begin their own independent monitoring, which are also finding disturbingly high levels of radiation. Kodama's centre, using 27 facilities to measure radiation across the country, has been closely monitoring the situation at Fukushima - and their findings are alarming.According to Dr Kodama, the total amount of radiation released over a period of more than five months from the ongoing Fukushima nuclear disaster is the equivalent to more than 29 "Hiroshima-type atomic bombs" and the amount of uranium released "is equivalent to 20" Hiroshima bombs.
  • Kodama, along with other scientists, is concerned about the ongoing crisis resulting from the Fukushima situation, as well as what he believes to be inadequate government reaction, and believes the government needs to begin a large-scale response in order to begin decontaminating affected areas.Distrust of the Japanese government's response to the nuclear disaster is now common among people living in the effected prefectures, and people are concerned about their health.Recent readings taken at the plant are alarming.When on August 2nd readings of 10,000 millisieverts (10 sieverts) of radioactivity per hour were detected at the plant, Japan's science ministry said that level of dose is fatal to humans, and is enough radiation to kill a person within one to two weeks after the exposure. 10,000 millisieverts (mSv) is the equivalent of approximately 100,000 chest x-rays.
  • t is an amount 250 per cent higher than levels recorded at the plant in March after it was heavily damaged by the earthquake and ensuing tsunami. The operator of Japan's crippled Fukushima Daiichi nuclear power plant, Tokyo Electric Power Company (TEPCO), that took the reading, used equipment to measure radiation from a distance, and was unable to ascertain the exact level because the device's maximum reading is only 10,000 mSv. TEPCO also detected 1,000 millisieverts (mSv) per hour in debris outside the plant, as well as finding 4,000 mSv per hour inside one of the reactor buildings.

  • he Fukushima disaster has been rated as a "level seven" on the International Nuclear and Radiological Event Scale (INES). This level, the highest, is the same as the Chernobyl nuclear disaster in 1986, and is defined by the scale as: "[A] major release of radioactive material with widespread health and environmental effects requiring implementation of planned and extended countermeasures."The Fukushima and Chernobyl disasters are the only nuclear accidents to have been rated level seven on the scale, which is intended to be logarithmic, similar to the scale used to describe the comparative magnitude of earthquakes. Each increasing level represents an accident approximately ten times more severe than the previous level.
  • Doctors in Japan are already treating patients suffering health effects they attribute to radiation from the ongoing nuclear disaster."We have begun to see increased nosebleeds, stubborn cases of diarrhoea, and flu-like symptoms in children," Dr Yuko Yanagisawa, a physician at Funabashi Futawa Hospital in Chiba Prefecture, told Al Jazeera.
  • She attributes the symptoms to radiation exposure, and added: "We are encountering new situations we cannot explain with the body of knowledge we have relied upon up until now.""The situation at the Daiichi Nuclear facility in Fukushima has not yet been fully stabilised, and we can't yet see an end in sight," Yanagisawa said. "Because the nuclear material has not yet been encapsulated, radiation continues to stream into the environment."
  • Al Jazeera's Aela Callan, reporting from Japan's Ibaraki prefecture, said of the recently detected high radiation readings: "It is now looking more likely that this area has been this radioactive since the earthquake and tsunami, but no one realised until now."Workers at Fukushima are only allowed to be exposed to 250 mSv of ionising radiation per year.
  • radioactive cesium exceeding the government limit was detected in processed tea made in Tochigi City, about 160km from the troubled Fukushima Daiichi nuclear plant, according to the Tochigi Prefectural Government, who said radioactive cesium was detected in tea processed from leaves harvested in the city in early July. The level is more than 3 times the provisional government limit.
  • anagisawa's hospital is located approximately 200km from Fukushima, so the health problems she is seeing that she attributes to radiation exposure causes her to be concerned by what she believes to be a grossly inadequate response from the government.From her perspective, the only thing the government has done is to, on April 25, raise the acceptable radiation exposure limit for children from 1 mSv/year to 20 mSv/year.
  • This has caused controversy, from the medical point of view," Yanagisawa told Al Jazeera. "This is certainly an issue that involves both personal internal exposures as well as low-dose exposures."Junichi Sato, Greenpeace Japan Executive Director, said: "It is utterly outrageous to raise the exposure levels for children to twenty times the maximum limit for adults."
  • The Japanese government cannot simply increase safety limits for the sake of political convenience or to give the impression of normality."Authoritative current estimates of the health effects of low-dose ionizing radiation are published in the Biological Effects of Ionising Radiation VII (BEIR VII) report from the US National Academy of Sciences.
  • he report reflects the substantial weight of scientific evidence proving there is no exposure to ionizing radiation that is risk-free. The BEIR VII estimates that each 1 mSv of radiation is associated with an increased risk of all forms of cancer other than leukemia of about 1-in-10,000; an increased risk of leukemia of about 1-in-100,000; and a 1-in-17,500 increased risk of cancer death.
  • r Helen Caldicott, the founding president of Physicians for Social Responsibility, a group that was awarded the Nobel Peace Prize in 1985, is equally concerned about the health effects from Japan's nuclear disaster."Radioactive elements get into the testicles and ovaries, and these cause genetic disease like diabetes, cystic fibrosis, and mental retardation," she told Al Jazeera. "There are 2,600 of these diseases that get into our genes and are passed from generation to generation, forever."
  • So far, the only cases of acute radiation exposure have involved TEPCO workers at the stricken plant. Lower doses of radiation, particularly for children, are what many in the medical community are most concerned about, according to Dr Yanagisawa.
  • Humans are not yet capable of accurately measuring the low dose exposure or internal exposure," she explained, "Arguing 'it is safe because it is not yet scientifically proven [to be unsafe]' would be wrong. That fact is that we are not yet collecting enough information to prove the situations scientifically. If that is the case, we can never say it is safe just by increasing the annual 1mSv level twenty fold."
  • Her concern is that the new exposure standards by the Japanese government do not take into account differences between adults and children, since children's sensitivity to radiation exposure is several times higher than that of adults.
  • Al Jazeera contacted Prime Minister Naoto Kan's office for comment on the situation. Speaking on behalf of the Deputy Cabinet Secretary for Public Relations for the Prime Minister's office, Noriyuki Shikata said that the Japanese government "refers to the ICRP [International Commission on Radiological Protection] recommendation in 2007, which says the reference levels of radiological protection in emergency exposure situations is 20-100 mSv per year. The Government of Japan has set planned evacuation zones and specific spots recommended for evacuation where the radiation levels reach 20 mSv/year, in order to avoid excessive radiation exposure."
  • he prime minister's office explained that approximately 23bn yen ($300mn) is planned for decontamination efforts, and the government plans to have a decontamination policy "by around the end of August", with a secondary budget of about 97bn yen ($1.26bn) for health management and monitoring operations in the affected areas. When questioned about the issue of "acute radiation exposure", Shikata pointed to the Japanese government having received a report from TEPCO about six of their workers having been exposed to more than 250 mSv, but did not mention any reports of civilian exposures.
  • Prime Minister Kan's office told Al Jazeera that, for their ongoing response to the Fukushima crisis, "the government of Japan has conducted all the possible countermeasures such as introduction of automatic dose management by ID codes for all workers and 24 hour allocation of doctors. The government of Japan will continue to tackle the issue of further improving the health management including medium and long term measures". Shikata did not comment about Kodama's findings.
  • Kodama, who is also a doctor of internal medicine, has been working on decontamination of radioactive materials at radiation facilities in hospitals of the University of Tokyo for the past several decades. "We had rain in Tokyo on March 21 and radiation increased to .2 micosieverts/hour and, since then, the level has been continuously high," said Kodama, who added that his reporting of radiation findings to the government has not been met an adequate reaction. "At that time, the chief cabinet secretary, Mr Edano, told the Japanese people that there would be no immediate harm to their health."
  • Kodama is an expert in internal exposure to radiation, and is concerned that the government has not implemented a strong response geared towards measuring radioactivity in food. "Although three months have passed since the accident already, why have even such simple things have not been done yet?" he said. "I get very angry and fly into a rage."
  • Radiation has a high risk to embryos in pregnant women, juveniles, and highly proliferative cells of people of growing ages. Even for adults, highly proliferative cells, such as hairs, blood, and intestinal epithelium cells, are sensitive to radiation."
  • Early on in the disaster, Dr Makoto Kondo of the department of radiology of Keio University's School of Medicine warned of "a large difference in radiation effects on adults compared to children".Kondo explained the chances of children developing cancer from radiation exposure was many times higher than adults.
  • Children's bodies are underdeveloped and easily affected by radiation, which could cause cancer or slow body development. It can also affect their brain development," he said.Yanagisawa assumes that the Japanese government's evacuation standards, as well as their raising the permissible exposure limit to 20mSv "can cause hazards to children's health," and therefore "children are at a greater risk".
  • Nishio Masamichi, director of Japan's Hakkaido Cancer Centre and a radiation treatment specialist, published an article on July 27 titled: "The Problem of Radiation Exposure Countermeasures for the Fukushima Nuclear Accident: Concerns for the Present Situation". In the report, Masamichi said that such a dramatic increase in permitted radiation exposure was akin to "taking the lives of the people lightly". He believes that 20mSv is too high, especially for children who are far more susceptible to radiation.
  • n early July, officials with the Japanese Nuclear Safety Commission announced that approximately 45 per cent of children in the Fukushima region had experienced thyroid exposure to radiation, according to a survey carried out in late March. The commission has not carried out any surveys since then.
  • Now the Japanese government is underestimating the effects of low dosage and/or internal exposures and not raising the evacuation level even to the same level adopted in Chernobyl," Yanagisawa said. "People's lives are at stake, especially the lives of children, and it is obvious that the government is not placing top priority on the people's lives in their measures."Caldicott feels the lack of a stronger response to safeguard the health of people in areas where radiation is found is "reprehensible".
  • Millions of people need to be evacuated from those high radiation zones, especially the children."
  • Dr Yanagisawa is concerned about what she calls "late onset disorders" from radiation exposure resulting from the Fukushima disaster, as well as increasing cases of infertility and miscarriages."Incidence of cancer will undoubtedly increase," she said. "In the case of children, thyroid cancer and leukemia can start to appear after several years. In the case of adults, the incidence of various types of cancer will increase over the course of several decades."Yanagisawa said it is "without doubt" that cancer rates among the Fukushima nuclear workers will increase, as will cases of lethargy, atherosclerosis, and other chronic diseases among the general population in the effected areas.
  • Radioactive food and water
  • An August 1 press release from Japan's MHLW said no radioactive materials have been detected in the tap water of Fukushima prefecture, according to a survey conducted by the Japanese government's Nuclear Emergency Response Headquarters. The government defines no detection as "no results exceeding the 'Index values for infants (radioactive iodine)'," and says "in case the level of radioactive iodine in tap water exceeds 100 Bq/kg, to refrain from giving infants formula milk dissolved by tap water, having them intake tap water … "
  • Yet, on June 27, results were published from a study that found 15 residents of Fukushima prefecture had tested positive for radiation in their urine. Dr Nanao Kamada, professor emeritus of radiation biology at Hiroshima University, has been to Fukushima prefecture twice in order to take internal radiation exposure readings and facilitated the study.
  • The risk of internal radiation is more dangerous than external radiation," Dr Kamada told Al Jazeera. "And internal radiation exposure does exist for Fukushima residents."According to the MHLW, distribution of several food products in Fukushima Prefecture remain restricted. This includes raw milk, vegetables including spinach, kakina, and all other leafy vegetables, including cabbage, shiitake mushrooms, bamboo shoots, and beef.
  • he distribution of tealeaves remains restricted in several prefectures, including all of Ibaraki, and parts of Tochigi, Gunma, Chiba, Kanagawa Prefectures.Iwate prefecture suspended all beef exports because of caesium contamination on August 1, making it the fourth prefecture to do so.
  • yunichi Tokuyama, an expert with the Iwate Prefecture Agricultural and Fisheries Department, told Al Jazeera he did not know how to deal with the crisis. He was surprised because he did not expect radioactive hot spots in his prefecture, 300km from the Fukushima nuclear plant."The biggest cause of this contamination is the rice straw being fed to the cows, which was highly radioactive," Tokuyama told Al Jazeera.
  • Kamada feels the Japanese government is acting too slowly in response to the Fukushima disaster, and that the government needs to check radiation exposure levels "in each town and village" in Fukushima prefecture."They have to make a general map of radiation doses," he said. "Then they have to be concerned about human health levels, and radiation exposures to humans. They have to make the exposure dose map of Fukushima prefecture. Fukushima is not enough. Probably there are hot spots outside of Fukushima. So they also need to check ground exposure levels."
  • Radiation that continues to be released has global consequences.More than 11,000 tonnes of radioactive water has been released into the ocean from the stricken plant.
  • Those radioactive elements bio-concentrate in the algae, then the crustaceans eat that, which are eaten by small then big fish," Caldicott said. "That's why big fish have high concentrations of radioactivity and humans are at the top of the food chain, so we get the most radiation, ultimately."

The nuclear power plans that have survived Fukushima [28Sep11] - 0 views

  • SciDev.Net reporters from around the world tell us which countries are set on developing nuclear energy despite the Fukushima accident. The quest for energy independence, rising power needs and a desire for political weight all mean that few developing countries with nuclear ambitions have abandoned them in the light of the Fukushima accident. Jordan's planned nuclear plant is part of a strategy to deal with acute water and energy shortages.
  • The Jordan Atomic Energy Commission (JAEC) wants Jordan to get 60 per cent of its energy from nuclear by 2035. Currently, obtaining energy from neighbouring Arab countries costs Jordan about a fifth of its gross domestic product. The country is also one of the world's most water-poor nations. Jordan plans to desalinate sea water from the Gulf of Aqaba to the south, then pump it to population centres in Amman, Irbid, and Zarqa, using its nuclear-derived energy. After the Fukushima disaster, Jordan started re-evaluating safety procedures for its nuclear reactor, scheduled to begin construction in 2013. The country also considered more safety procedures for construction and in ongoing geological and environmental investigations.
  • The government would not reverse its decision to build nuclear reactors in Jordan because of the Fukushima disaster," says Abdel-Halim Wreikat, vice Chairman of the JAEC. "Our plant type is a third-generation pressurised water reactor, and it is safer than the Fukushima boiling water reactor." Wreikat argues that "the nuclear option for Jordan at the moment is better than renewable energy options such as solar and wind, as they are still of high cost." But some Jordanian researchers disagree. "The cost of electricity generated from solar plants comes down each year by about five per cent, while the cost of producing electricity from nuclear power is rising year after year," says Ahmed Al-Salaymeh, director of the Energy Centre at the University of Jordan. He called for more economic feasibility studies of the nuclear option.

  • And Ahmad Al-Malabeh, a professor in the Earth and Environmental Sciences department of Hashemite University, adds: "Jordan is rich not only in solar and wind resources, but also in oil shale rock, from which we can extract oil that can cover Jordan's energy needs in the coming years, starting between 2016 and 2017 ... this could give us more time to have more economically feasible renewable energy."
  • Finance, rather than Fukushima, may delay South Africa's nuclear plans, which were approved just five days after the Japanese disaster. South Africa remains resolute in its plans to build six new nuclear reactors by 2030. Katse Maphoto, the director of Nuclear Safety, Liabilities and Emergency Management at the Department of Energy, says that the government conducted a safety review of its two nuclear reactors in Cape Town, following the Fukushima event.
  • Vietnam's nuclear energy targets remain ambitious despite scientists' warning of a tsunami risk. Vietnam's plan to power 10 per cent of its electricity grid with nuclear energy within 20 years is the most ambitious nuclear energy plan in South-East Asia. The country's first nuclear plant, Ninh Thuan, is to be built with support from a state-owned Russian energy company and completed by 2020. Le Huy Minh, director of the Earthquake and Tsunami Warning Centre at Vietnam's Institute of Geophysics, has warned that Vietnam's coast would be affected by tsunamis in the adjacent South China Sea.
  • Larkin says nuclear energy is the only alternative to coal for generating adequate electricity. "What other alternative do we have? Renewables are barely going to do anything," he said. He argues that nuclear is capable of supplying 85 per cent of the base load, or constantly needed, power supply, while solar energy can only produce between 17 and 25 per cent. But, despite government confidence, Larkin says that a shortage of money may delay the country's nuclear plans.
  • The government has said yes but hasn't said how it will pay for it. This is going to end up delaying by 15 years any plans to build a nuclear station."
  • The Ninh Thuan nuclear plant would sit 80 to 100 kilometres from a fault line on the Vietnamese coast, potentially exposing it to tsunamis, according to state media. But Vuong Huu Tan, president of the state-owned Vietnam Atomic Energy Commission, told state media in March, however, that lessons from the Fukushima accident will help Vietnam develop safe technologies. And John Morris, an Australia-based energy consultant who has worked as a geologist in Vietnam, says the seismic risk for nuclear power plants in the country would not be "a major issue" as long as the plants were built properly. Japan's nuclear plants are "a lot more earthquake prone" than Vietnam's would be, he adds.
  • Undeterred by Fukushima, Nigeria is forging ahead with nuclear collaborations. There is no need to panic because of the Fukushima accident, says Shamsideen Elegba, chair of the Forum of Nuclear Regulatory Bodies in Africa. Nigeria has the necessary regulatory system to keep nuclear activities safe. "The Nigerian Nuclear Regulatory Authority [NNRA] has established itself as a credible organisation for regulatory oversight on all uses of ionising radiation, nuclear materials and radioactive sources," says Elegba who was, until recently, the NNRA's director general.
  • Vietnam is unlikely to experience much in the way of anti-nuclear protests, unlike neighbouring Indonesia and the Philippines, where civil society groups have had more influence, says Kevin Punzalan, an energy expert at De La Salle University in the Philippines. Warnings from the Vietnamese scientific community may force the country's ruling communist party to choose alternative locations for nuclear reactors, or to modify reactor designs, but probably will not cause extreme shifts in the one-party state's nuclear energy strategy, Punzalan tells SciDev.Net.
  • Will the Philippines' plans to rehabilitate a never-used nuclear power plant survive the Fukushima accident? The Philippines is under a 25-year moratorium on the use of nuclear energy which expires in 2022. The government says it remains open to harnessing nuclear energy as a long-term solution to growing electricity demand, and its Department of Science and Technology has been making public pronouncements in favour of pursuing nuclear energy since the Fukushima accident. Privately, however, DOST officials acknowledge that the accident has put back their job of winning the public over to nuclear by four or five years.
  • In the meantime, the government is trying to build capacity. The country lacks, for example, the technical expertise. Carmencita Bariso, assistant director of the Department of Energy's planning bureau, says that, despite the Fukushima accident, her organisation has continued with a study on the viability, safety and social acceptability of nuclear energy. Bariso says the study would include a proposal for "a way forward" for the Bataan Nuclear Power Plant, the first nuclear reactor in South East Asia at the time of its completion in 1985. The $2.3-billion Westinghouse light water reactor, about 60 miles north of the capital, Manila, was never used, though it has the potential to generate 621 megawatts of power. President Benigno Aquino III, whose mother, President Corazon Aquino, halted work on the facility in 1986 because of corruption and safety issues, has said it will never be used as a nuclear reactor but could be privatised and redeveloped as a conventional power plant.
  • But Mark Cojuangco, former lawmaker, authored a bill in 2008 seeking to start commercial nuclear operations at the Bataan reactor. His bill was not passed before Congress adjourned last year and he acknowledges that the Fukushima accident has made his struggle more difficult. "To go nuclear is still the right thing to do," he says. "But this requires a societal decision. We are going to spark public debates with a vengeance as soon as the reports from Fukushima are out." Amended bills seeking both to restart the reactor, and to close the issue by allowing either conversion or permanent closure, are pending in both the House and the Senate. Greenpeace, which campaigns against nuclear power, believes the Fukushima accident has dimmed the chances of commissioning the Bataan plant because of "increased awareness of what radioactivity can do to a place". Many parts of the country are prone to earthquakes and other natural disasters, which critics say makes it unsuitable both for the siting of nuclear power stations and the disposal of radioactive waste.
  • In Kenya, nuclear proponents argue for a geothermal – nuclear mix In the same month as the Fukushima accident, inspectors from the International Atomic Energy Agency approved Kenya's application for its first nuclear power station (31 March), a 35,000 megawatt facility to be built at a cost of Sh950 billion (US$9.8 billion) on a 200-acre plot on the Athi Plains, about 50km from Nairobi
  • The plant, with construction driven by Kenya's Nuclear Electricity Project Committee, should be commissioned in 2022. The government claims it could satisfy all of Kenya's energy needs until 2040. The demand for electricity is overwhelming in Kenya. Less than half of residents in the capital, Nairobi, have grid electricity, while the rural rate is two per cent. James Rege, Chairman of the Parliamentary Committee on Energy, Communication and Information, takes a broader view than the official government line, saying that geothermal energy, from the Rift Valley project is the most promising option. It has a high production cost but remains the country's "best hope". Nuclear should be included as "backup". "We are viewing nuclear energy as an alternative source of power. The cost of fossil fuel keeps escalating and ordinary Kenyans can't afford it," Rege tells SciDev.Net.
  • Hydropower is limited by rivers running dry, he says. And switching the country's arable land to biofuel production would threaten food supplies. David Otwoma, secretary to the Energy Ministry's Nuclear Electricity Development Project, agrees that Kenya will not be able to industrialise without diversifying its energy mix to include more geothermal, nuclear and coal. Otwoma believes the expense of generating nuclear energy could one day be met through shared regional projects but, until then, Kenya has to move forward on its own. According to Rege, much as the nuclear energy alternative is promising, it is extremely important to take into consideration the Fukushima accident. "Data is available and it must be one step at a time without rushing things," he says. Otwoma says the new nuclear Kenya can develop a good nuclear safety culture from the outset, "but to do this we need to be willing to learn all the lessons and embrace them, not forget them and assume that won't happen to us".
  • But the government adopted its Integrated Resource Plan (IRP) for 2010-2030 five days after the Fukushima accident. Elliot Mulane, communications manager for the South African Nuclear Energy Corporation, (NECSA) a public company established under the 1999 Nuclear Energy Act that promotes nuclear research, said the timing of the decision indicated "the confidence that the government has in nuclear technologies". And Dipuo Peters, energy minister, reiterated the commitment in her budget announcement earlier this year (26 May), saying: "We are still convinced that nuclear power is a necessary part of our strategy that seeks to reduce our greenhouse gas emissions through a diversified portfolio, comprising some fossil-based, renewable and energy efficiency technologies". James Larkin, director of the Radiation and Health Physics Unit at the University of the Witwatersrand, believes South Africa is likely to go for the relatively cheap, South Korean generation three reactor.
  • It is not only that we say so: an international audit came here in 2006 to assess our procedure and processes and confirmed the same. Elegba is firmly of the view that blame for the Fukushima accident should be allocated to nature rather than human error. "Japan is one of the leaders not only in that industry, but in terms of regulatory oversight. They have a very rigorous system of licensing. We have to make a distinction between a natural event, or series of natural events and engineering infrastructure, regulatory infrastructure, and safety oversight." Erepamo Osaisai, Director General of the Nigeria Atomic Energy Commission (NAEC), has said there is "no going back" on Nigeria's nuclear energy project after Fukushima.
  • Nigeria is likely to recruit the Russian State Corporation for Atomic Energy, ROSATOM, to build its first proposed nuclear plant. A delegation visited Nigeria (26- 28 July) and a bilateral document is to be finalised before December. Nikolay Spassy, director general of the corporation, said during the visit: "The peaceful use of nuclear power is the bedrock of development, and achieving [Nigeria's] goal of being one of the twenty most developed countries by the year 2020 would depend heavily on developing nuclear power plants." ROSATOM points out that the International Atomic Energy Agency monitors and regulates power plant construction in previously non-nuclear countries. But Nnimmo Bassey, executive director of the Environmental Rights Action/Friends of the Earth Nigeria (ERA/FoEN), said "We cannot see the logic behind the government's support for a technology that former promoters in Europe, and other technologically advanced nations, are now applying brakes to. "What Nigeria needs now is investment in safe alternatives that will not harm the environment and the people. We cannot accept the nuclear option."
  • Thirsty for electricity, and desirous of political clout, Egypt is determined that neither Fukushima ― nor revolution ― will derail its nuclear plans. Egypt was the first country in the Middle East and North Africa to own a nuclear programme, launching a research reactor in 1961. In 2007 Egypt 'unfroze' a nuclear programme that had stalled in the aftermath of the Chernobyl disaster. After the Egyptian uprising in early 2011, and the Fukushima accident, the government postponed an international tender for the construction of its first plant.
  • Yassin Ibrahim, chairman of the Nuclear Power Plants Authority, told SciDev.Net: "We put additional procedures in place to avoid any states of emergency but, because of the uprising, the tender will be postponed until we have political stability after the presidential and parliamentary election at the end of 2011". Ibrahim denies the nuclear programme could be cancelled, saying: "The design specifications for the Egyptian nuclear plant take into account resistance to earthquakes and tsunamis, including those greater in magnitude than any that have happened in the region for the last four thousand years. "The reactor type is of the third generation of pressurised water reactors, which have not resulted in any adverse effects to the environment since they began operation in the early sixties."
  • Ibrahim El-Osery, a consultant in nuclear affairs and energy at the country's Nuclear Power Plants Authority, points out that Egypt's limited resources of oil and natural gas will run out in 20 years. "Then we will have to import electricity, and we can't rely on renewable energy as it is still not economic yet — Egypt in 2010 produced only two per cent of its needs through it." But there are other motives for going nuclear, says Nadia Sharara, professor of mineralogy at Assiut University. "Owning nuclear plants is a political decision in the first place, especially in our region. And any state that has acquired nuclear technology has political weight in the international community," she says. "Egypt has the potential to own this power as Egypt's Nuclear Materials Authority estimates there are 15,000 tons of untapped uranium in Egypt." And she points out it is about staying ahead with technology too. "If Egypt freezes its programme now because of the Fukushima nuclear disaster it will fall behind in many science research fields for at least the next 50 years," she warned.

Quake's jolts were double nuke plant's design - North Anna Plant, USA [08Sep11] - 5 views

shared by D'coda Dcoda on 08 Sep 11 - No Cached
  • The magnitude-5.8 earthquake last month in Virginia caused about twice as much ground shaking as a nearby nuclear power plant was designed to withstand, according to a preliminary federal analysis.
  • Parts of the North Anna Power Station in Mineral, Va., 11 miles from its epicenter, endured jolts equal to 26% of the force of gravity (0.26g) from some of the higher-frequency vibrations unleashed by the quake, said Scott Burnell, spokesman of the Nuclear Regulatory Commission.
  • An NRC document says the reactors' containment structure was built to withstand 12% of the force of gravity (0.12g.) Dominion, the power company that operates the plant, says parts of the plant can handle up to 0.18g.STORY: Quake readiness of nuclear power plants unclear

  • "It's the things inside the buildings that may have been shaken more than the design called for," Burnell said, adding that the buildings themselves appear to have been less affected. He said the analysis is based on a seismograph reading taken about 30 miles away by the U.S. Geological Survey.
  • Whatever the final numbers on shaking or ground motion, the plant withstood the jolts, Burnell said, indicating there's a "great deal" of safety margin."That margin was certainly enough for North Anna this time," he said.
  • "Maybe you shouldn't rely on the margin," said Edwin Lyman at the Union of Concerned Scientists, an organization critical of nuclear energy. "The jury is still out," he said, on whether the plant was adequately designed.The two reactors at the North Anna plant, which began operation in 1978 and 1980, have remained closed since the Aug. 23 quake. They automatically shut down after losing off-site power. Backup diesel generators kept their cores cool until electricity was restored several hours later.
  • Dan Stoddard, Dominion's senior vice president of operations, said Friday that initial readings from the facility's scratch plates and other monitors indicate its shaking during the quake exceeded its design, but he declined to give numbers. Dominion officials plan to brief the NRC today on those findings.

UK public confidence in nuclear remains steady despite Fukushima [09Sep11] - 0 views

  • The accident at Fukushima in Japan in March this year seems to have had little overall impact on the UK public's confidence in nuclear power, according to a poll.The survey, carried out by Populus last month and commissioned by the British Science Association, found that 41% of respondents agreed the benefits of nuclear power outweighed the risks, up from 38% in 2010 and 32% in 2005. Those who said that the risks greatly or slightly outweighed the benefits of nuclear power in 2010 numbered 36%, and in 2011 this dropped to 28% of respondents.
  • "It's genuinely surprising to me that views have returned to these early 2010 levels quite so quickly and slightly more positively," said Nick Pidgeon of the University of Cardiff, who discussed the findings of the latest poll at a briefing to mark the launch of the British Science Festival, which starts in Bradford on Saturday. "There's been a lot of speculation about the impacts of Fukushima on public attitudes – this is the first fully independent study we've had in the UK."Though overall support was up, there was a striking difference between men and women, with 53% of men in favour of nuclear power but only 21% of women supportive. "If you dig into the data, you see that men in particular become much more confident about nuclear energy," said Pidgeon.Monbiot effectHe also said that blanket media coverage and commentary – something he referred to as the "George Monbiot effect" – may have had a positive effect on public attitudes because, despite the severity of the crisis, no one has so far died.
  • Populus interviewed 2,050 adults between 26 and 29 August and weighted its results to ensure they were representative of the British population.Overall, the support for nuclear power has been gradually increasing for about 10 years, said Pidgeon, and, in the past five years, the majority of people in Britain has come to support the renewal of the nuclear programme.Pidgeon said that polls in the direct aftermath of the Fukushima accident had showed a dip in support for nuclear in the UK and elsewhere, though confidence did not collapse. "There were still more people, even immediately afterwards, in favour of nuclear energy than against in Britain," he said.

  • The focus of potential concerns has also shifted in the wake of Fukushima. "If you asked people why they were unhappy about nuclear energy a year ago, they would have brought waste up," said Pidgeon. "What is clear from other polling is that accidents have gone to the top of what people are now concerned about with nuclear energy, the waste has dropped further down."
  • Bryony Worthington, a Labour peer and environmental campaigner, said that for the general public the perception of the main cause of the Fukushima problem had not been the design of the reactor but the siting of the power plant. "Most people said, hang on, why did you put them all on that eastern seaboard, which is a seismically unstable region?"The withdrawal of support for future nuclear power stations by the German government, she said, was political. "For Angela Merkel to reverse her decision and phase out the nuclear, Fukushima gave her a good opportunity to do it. She was already under huge political pressure to do that and Fukushima was just the trigger she found politically expedient to do it."

Japanese jr. high radiation education: Science education or brainwashing? [20Sep11] - 0 views

shared by D'coda Dcoda on 20 Sep 11 - No Cached
  • The Japanese Science and Education Ministry (MEXT), is mandating a new curriculum which includes radiation education to be taught at schools across Japan. MEXT doesn't only mandate education standards, they define specific material and teaching techniques in many cases. This video analyzes the new radiation education curriculum. This is the same ministry that is responsible for setting some of the sky-high radiation "safety" standards with regards to the Fukushima disaster.This curriculum is aimed at junior high school and is thus compulsory education that all children in Japan will receive. Japanese junior high school is grades 8-10.

Nuclear Island opens to UK students [16Jun11] - 0 views

  • UK science and engineering students will be able to experience building a scaled down nuclear power plant as part of a new training programme known as the Nuclear Island.   The programme was officially launched on 15 June, when a pilot week began with 25 engineering students from Imperial College London designing and constructing a scaled down nuclear power plant. They will be assessed in relation to real-life skills such as radiation protection, site licensing, budgetary control and project management. The pilot week is scheduled to end with a yet to be unveiled safety breach, which will test the students' ability to respond to a potential disaster scenario.
  • The Nuclear Island has been developed by a partnership of Imperial College London, Constructionarium, Cogent Sector Skills Council, the Engineering Construction Industry Training Board (ECITB) and Construction Skills. The partnership received funding to develop the project from the National Higher Education Science, Technology, Engineering and Mathematics (HE STEM) Programme and the Royal Academy of Engineers.
  • The Nuclear Island will be a hands-on new build experience for students initially in engineering, but will be broadened out to other science, technology, engineering and mathematical areas as part of the pilot programme. According to Cogent, "For the first time, nuclear safety culture will be an essential part of construction engineering courses, embedding critical safety behaviours from day one."

A Labor Shortage for U.S. Nuclear Plants [07Jul11] - 0 views

  • It took Japan’s Fukushima disaster to make nuclear energy interesting to students in Karl Craddock’s advanced placement chemistry class at William Fremd High School in Palatine, Ill. Too bad the buzz was about radiation plumes, iodine pills, and potential deadly threats at nuclear power plants that generate more than half the electricity in Illinois. It wasn’t the sort of talk to get kids excited about a career in nuclear energy. “It doesn’t have the cool factor right now, that’s for sure,” says Craddock, who has taught science at the suburban Chicago high school for seven years.
  • Nuclear utilities in the U.S. will need to hire nearly 25,000 people to replace the 39 percent of its workforce that will be eligible for retirement by 2016, says Carol L. Berrigan, senior director for industry infrastructure for the Nuclear Energy Institute, a Washington-based trade group. Meanwhile, U.S. universities awarded a total of 715 graduate and undergraduate degrees in nuclear engineering in 2009, the most recent year for which data is available.
  • After nuclear plant disasters at Three Mile Island in Pennsylvania and Chernobyl in Ukraine, nuclear power lost political support in the U.S. Hiring slowed through the 1990s and nuclear workers under the age of 40 became a rarity as talk turned from expansion to shutting down existing plants. “That’s not an exciting prospect for a young person thinking about their career,” says K.L. “Lee” Peddicord, a professor of nuclear engineering and director of the Nuclear Power Institute at Texas A&M University.

  • With nuclear power out of favor, the number of academic institutions offering degrees shrank to 32 in 2010 from 77 in 1975, according to the Oak Ridge Institute for Science and Education. Bachelor’s degrees awarded in nuclear engineering fell to 120 in 2001, from 863 in 1978. Power companies and engineering schools redoubled their recruiting efforts in recent years to replace retiring baby boomers and staff the 34 new plants that were on the drawing boards as of 2009. Urged by two utilities with nuclear ambitions in Texas—South Texas Project and Exelon (EXC) —Texas A&M University in College Station launched the Nuclear Power Institute in 2008 to spearhead a statewide effort to train 2,000 nuclear workers, boost math and science programs at high schools, and develop a new two-year nuclear training degree with community colleges based near eight proposed new plants.
  • The Nuclear Power Institute has graduated its first two classes of technicians, yet Peddicord worries that the weak economy and the growing uncertainty overhanging a U.S. nuclear expansion will depress interest in the program. The partners in two new reactors planned for nearby Bay City— NRG Energy (NRG) and Tokyo Electric Power, operator of the crippled Fukushima Dai-Ichi power plant—yanked funding for the project after the disaster. “The real test will come in the fall, when we look at enrollment,” he says.
  • The bottom line: Nuclear plants in the U.S. need to recruit some 25,000 new workers by 2016. Japan’s nuclear crisis has made reaching that goal harder.
