San Clemente won't add nuclear critics to meeting [07Sep11] - 0 views

  • Critics of nuclear power won't be among the invited presenters at a Sept. 27 community meeting in San Clemente to discuss lessons learned from Japan's Fukushima nuclear-plant emergency.The City Council on Tuesday night denied San Clemente Green's request to be allowed to present 30 minutes of testimony from three of its own invited speakers. City Manager George Scarborough said the U.S. Nuclear Regulatory Commission's participation in the meeting could be jeopardized if the city tries to change the agreed-to agenda.
  • Last spring, the City Council asked the NRC and Southern California Edison to participate in a public meeting to convey what has been learned from Fukushima and how it might affect the way Edison operates the San Onofre Nuclear Generating Station about two miles south of San Clemente. On Aug. 16, San Clemente Green asked the council to also allocate 45 minutes for speakers with alternative views.At the time, Scarborough said the city had already sent the NRC an agenda for the meeting and that the NRC had not confirmed it would attend. Since then, the NRC has agreed to participate based on that agenda, with NRC personnel scheduled to leave at 9:30 p.m., Scarborough said.

Almost 500 millisieverts of radiation for some in corridor NW [06Sep11] - 0 views

  • There’s a denial of the severity of the accident by the business community and government in Tokyo… they are ignoring and denying severity of problem… Some towns in the NW corridor received 50 rem of radiation, people in those towns received 50 rems.. that means there is almost a 50/50 chance of cancer… that information just came out now 6 months after accident…

Amano: New nuclear remains on the agenda [13Sep11] - 0 views

  • The worldwide use of nuclear energy will continue to grow despite the Fukushima Daiichi accident, the director general of the International Atomic Energy Agency (IAEA), Yukiya Amano, told a meeting of its Board of Governors. Non-proliferation concerns remain in some countries, he noted.
  • "We now expect the number of operating nuclear reactors in the world to increase by about 90 by 2030, in our low projection, or by around 350, in our high projection, compared to the current total of 432 reactors," Amano told the board. "This represents continuous and significant growth in the use of nuclear power, but at a slower growth rate than in our previous projections."
  • He noted that most of this growth will occur in countries already operating nuclear power plants, especially in Asia. "China and India will remain the main centres of expansion and their nuclear power capacities by 2030 are expected to be as projected before the accident, after a temporary period of slower growth," Amano said. "The projected slowdown in global growth reflects an accelerated phase-out of nuclear power in Germany, some immediate shutdowns and a government review of the planned expansion in Japan, and temporary delays in expansion in several other countries."   According to Amano, interest remains strong in countries considering introducing nuclear energy. He said that the factors that contributed to increasing interest in nuclear energy before the accident remain unchanged: "increasing global demand for energy, as well as concerns about climate change, dwindling reserves of oil and gas and uncertainty of supply of fossil fuels." However, he noted that "a few countries have cancelled or revised their plans, while others have taken a 'wait and see' approach."

  • Amano told the board that the situation at the Fukushima Daiichi site "remained very serious for many months," but the IAEA's assessment now is that the reactors are "essentially stable and the expectation is that the 'cold shutdown' of all the reactors will be achieved as planned."   Amano presented the IAEA board with a draft of a new Nuclear Safety Action Plan, the "result of an intensive process of consultations with member states." He told the meeting, "The draft Nuclear Safety Action Plan represents a significant step forward in strengthening nuclear safety. We must not lose our sense of urgency. I hope the draft action plan will be approved by the board and endorsed by the General Conference next week."
  • "In the aftermath of Fukushima Daiichi, the most important thing is to ensure transparency, build confidence, and meet the high expectations of the public. But it is actions, not words, that count. With this plan we will move from the planning phase to the implementation phase ... Further lessons will be learned and the plan will be updated accordingly."   "It will take rapid and visible improvements in nuclear safety - not just good intentions - to restore public confidence in nuclear power. The agency will play its central part with vigour."

Nishikawa seeks better safety tests for reactors [15Sep11] - 0 views

  • Fukui Gov. Issei Nishikawa on Thursday told trade minister Yukio Edano that the central government needs to start using more adequate safety tests that reflect the lessons being learned from the Fukushima crisis before restarting reactors now undergoing regular checkups. In a written request submitted to Edano, the governor of Fukui Prefecture, which at 14 has more reactors than any other prefecture, called on the government to promptly share knowledge and data obtained from the accident and demonstrate a "responsible" energy policy for the future of nuclear power. In the statement, Nishikawa criticized how the nuclear crisis was handled under Prime Minister Naoto Kan — including his request to close only the Hamaoka power plant in Shizuoka Prefecture — and the abrupt introduction of reactor stress tests, saying they were done in an "impromptu" manner.
  • "We hope the (new) government will quickly present responsible visions for securing energy and for the future prospects of nuclear power," Nishikawa said in the document. In the meeting with Nishikawa at the Ministry of Economy, Trade and Industry, Edano expressed regret about the trouble and anxiety to residents caused by the Fukushima nuclear crisis and said the government will strive to make the process of allowing reactor restarts trustworthy and transparent. A number of reactors undergoing regular checkups remain halted amid heightened public concern ever since the March quake and tsunami triggered the crisis at the Fukushima No. 1 power plant in Fukushima Prefecture.
  • The new Cabinet is headed by Prime Minister Yoshihiko Noda, who has said it will be difficult to build new nuclear power plants in Japan and that reactors that have reached the end of their lifetimes should be decommissioned. Nishikawa's requests to the government included a rule on how long reactors older than 40 years should be permitted to run, and a sufficient explanation of the reasons for requesting the shutdown of only the Hamaoka power plant. Nishikawa also met Education, Culture, Sports, Science and Technology Minister Masaharu Nakagawa and asked him to ensure the safety of the trouble-prone Monju prototype fast-breeder reactor in Fukui.

Americans' Support for Nuclear Energy Holds at Majority Level 6 Months After Japan Acci... - 0 views

  • WASHINGTON, Oct. 3, 2011 -- /PRNewswire-USNewswire/ -- Six months after the Fukushima Daiichi accident in Japan, solid majorities of Americans still view nuclear energy favorably, still support the extension of operating licenses at existing facilities that meet federal safety standards, and still believe that construction of a new reactor is acceptable at the site of the nearest nuclear power plant that already is operating, a new national survey shows.While support for nuclear energy has declined from the historically high level seen one year ago, support on a variety of measures is holding at the majority levels found consistently in public opinion surveys conducted throughout the past decade.
  • Nuclear energy supplies electricity to 20 percent of U.S. homes and businesses, even though the 104 nuclear facilities operating in 31 states constitute only 10 percent of the nation's electric generating capacity.Eighty-five percent of those surveyed agree that, "When their original operating licenses expire, we should renew the license of nuclear power plants that continue to meet federal safety standards." Seven months ago, 88 percent of Americans agreed with this statement.
  • "While there is some evidence of impact of the Fukushima events, support for nuclear energy continues at much higher levels than in earlier decades," company President Ann Bisconti said. "Turmoil in oil-rich areas of the world and hikes in oil prices historically have focused public opinion even more on nuclear energy, and may have helped to preclude serious impact of events in Japan on public attitudes."Despite the Fukushima accident, 67 percent of Americans rate U.S. nuclear power plant safety high. This is identical to the safety rating found in a national survey last February, one month prior to the earthquake and tsunami that caused the Fukushima accident. Eighty-two percent of Americans believe that "we should learn the lessons from the Japanese accident and continue to develop advanced nuclear energy plants to meet America's growing electricity demand," the new survey showed.

  • In the new telephone survey of 1,000 U.S. adults, 62 percent of respondents said they favor the use of nuclear energy as one of the ways to provide electricity in the United States, with 35 percent opposed. Those strongly favoring nuclear energy outnumber those strongly opposed by a two-to-one ratio, 28 percent vs. 13 percent, according to the survey conducted Sept. 22-24 by Bisconti Research Inc. with GfK Roper. The survey was sponsored by the Nuclear Energy Institute and has a margin of error of plus or minus three percentage points. Numerous surveys conducted by Bisconti Research over the past decade show that public support for nuclear energy topped 60 percent each year, rising as high as 74 percent of Americans in March 2010.
  • In the latest survey, 59 percent of Americans agree, "We should definitely build more nuclear power plants in the future." Thirty-eight percent disagree. Still, 75 percent of Americans agree that, "Electric utilities should prepare now so that new nuclear power plants could be built if needed in the next decade." Twenty-two percent disagree.Two-thirds of Americans (67 percent) say they would find a new reactor acceptable at the site of the nearest nuclear power plant that already is operating, while 28 percent find this unacceptable. Seven months ago, 76 percent of Americans found this expansion acceptable, with 20 percent saying it was not acceptable.
  • "This survey, like other recent surveys, confirms that large majorities of Americans associate nuclear energy with issues they care about, including clean air, reliable and affordable electricity, energy independence, and economic growth and job creation," Bisconti said.Details on the new survey are accessible at: http://www.nei.org/resourcesandstats/documentlibrary/reliableandaffordableenergy/reports/latest-trends-in-us-public-opinion-about-nuclear-energy-sept-2011.

Senate Appropriators on Nuclear Energy [16Sep11] - 0 views

shared by D'coda Dcoda on 09 Oct 11 - No Cached
  • The Senate Energy and Water Development Appropriations Subcommittee included extensive language in their FY 2012 committee report about nuclear energy.  They wrote of being “extremely concerned that the United States continues to accumulate spent fuel from nuclear reactors without a comprehensive plan to collect the fuel or dispose of it safely, and as a result faces a $15,400,000,000 liability by 2020,” called for the development of “consolidated regional storage facilities,” and mandated research on dry cask storage, advanced fuel cycle options, and disposal in geological media.  The appropriators provided no funding for the Next Generation Nuclear Plant program or Light Water Reactor Small Modular Reactor Licensing Technical Support.  In a separate section, they direct the Nuclear Regulatory Commission to contract with the National Academy of Sciences for a study on the lessons learned from the Fukushima nuclear disaster, and discuss beyond design-basis events and mitigating impacts of earthquakes. Language from the committee report 112-75 follows, with page number references to the pdf version of this document.
  • Nuclear Energy The FY 2011 appropriation was $732.1 million The FY 2012 administration request was $754.0 million The FY 2012 House-passed bill provides $733.6 million, an increase of $1.5 million or 0.2 percent from the current budget. The Senate Appropriations Committee bill provides $583.8 million, a decline of $148.3 million or 20.3 percent.
  • “The Committee has provided more than $500,000,000 in prior years toward the Next Generation Nuclear Plant [NGNP] program.  Although the program has experienced some successes, particularly in the advanced research and development of TRISO [tristructural-isotropic] fuel, the Committee is frustrated with the lack of progress and failure to resolve the upfront cost-share issue to allocate the risk between industry and the Federal Government. Although the Committee has provided sufficient time for these issues to be resolved, the program has stalled. Recognizing funding constraints, the Committee cannot support continuing the program in its current form. The Committee provides no funding to continue the existing NGNP program, but rather allows the Department to continue high-value, priority research and development activities for high-temperature reactors, in cooperation with industry, that were included in the NGNP program.”

  • “While the Nuclear Regulatory Commission has found that spent nuclear fuel can be stored safely for at least 60 years in wet or dry cask storage beyond the licensed life of the reactor, the Committee has significant questions on this matter and is extremely concerned that the United States continues to accumulate spent fuel from nuclear reactors without a comprehensive plan to collect the fuel or dispose of it safely, and as a result faces a $15,400,000,000 liability by 2020. The Committee approved funding in prior years for the Blue Ribbon Commission on America’s Nuclear Future [BRC], which was charged with examining our Nation’s policies for managing the back end of the nuclear fuel cycle and recommending a new plan. The BRC issued a draft report in July 2011 with recommendations, which is expected to be finalized in January 2012. The Committee directs prior existing funding, contingent on the renewal of its charter, to the BRC to develop a comprehensive revision to Federal statutes based on its recommendations, to submit to Congress for its consideration.
  • “The Committee directs the Department to develop and prepare to implement a strategy for the management of spent nuclear fuel and other nuclear waste within 3 months of publication of the final report of the Blue Ribbon Commission on America’s Nuclear Future.  The strategy shall reduce long-term Federal liability associated with the Department’s failure to pick up spent fuel from commercial nuclear reactors, and it should propose to store waste in a safe and responsible manner. The Committee notes that a sound Federal strategy will likely require one or more consolidated storage facilities with adequate capacity to be sited, licensed, and constructed in multiple regions, independent of the schedule for opening a repository. The Committee directs that the Department’s strategy include a plan to develop consolidated regional storage facilities in cooperation with host communities, as necessary, and propose any amendments to Federal statute necessary to implement the strategy.
  • “Although successfully disposing of spent nuclear fuel permanently is a long-term effort and will require statutory changes, the Committee supports taking near- and mid-term steps that can begin without new legislation and which provide value regardless of the ultimate policy the United States adopts. The Committee therefore includes funding for several of these steps in the Nuclear Energy Research and Development account, including the assessment of dry casks to establish a scientific basis for licensing; continued work on advanced fuel cycle options; research to assess disposal in different geological media; and the development of enhanced fuels and materials that are more resistant to damage in reactors or spent fuel pools.
  • (Page 80) “The events at the Fukushima-Daiichi facilities in Japan have resulted in a reexamination of our Nation’s policies regarding the safety of commercial reactors and the storage of spent nuclear fuel.  These efforts have been supported by appropriations in this bill, and the Committee provides funding for continuation and expansion of these activities.
  • The report also contains extensive language regarding Nuclear Energy Research and Development: “Use of Prior Existing Balances. - If the Secretary renews the charter of the Blue Ribbon Commission, the Department is directed to use $2,500,000 of prior existing balances appropriated to the Office of Civilian Radioactive Waste Management to develop a comprehensive revision to Federal statutes based on its recommendations.  The recommendation should be provided to Congress not later than March 30, 2012 for consideration.
  • “Nuclear Energy Enabling Technologies. - The Committee recommends $68,880,000 for Nuclear Energy Enabling Technologies, including $24,300,000 for the Energy Innovation Hub for Modeling and Simulation, $14,580,000 for the National Science User Facility at Idaho National Laboratory, and $30,000,000 for Crosscutting research.  The Committee does not recommend any funding for Transformative research. The Committee recommends that the Department focus the Energy Innovation Hub on the aspects of its mission that improve nuclear powerplant safety.
  • Light Water Reactor Small Modular Reactor Licensing Technical Support. - The Committee provides no funding for Light Water Reactor Small Modular Reactor Licensing Technical Support. “Reactor Concepts Research, Development, and Demonstration. - The Committee provides $31,870,000 for Reactor Concepts Research, Development and Demonstration. Of this funding, $21,870,000 is for Advanced Reactor Concepts activities. The Committee does not include funding for the Next Generation Nuclear Plant Demonstration project. The Department may, within available funding, continue high-value, priority research and development activities for high-temperature reactor concepts, in cooperation with industry, that were conducted as part of the NGNP program.  The remaining funds, $10,000,000, are for research and development of the current fleet of operating reactors to determine how long they can safely operate.
  • “Fuel Cycle Research and Development. - The Committee recommends $187,917,000 for Fuel Cycle Research and Development.  Within available funds, the Committee provides $10,000,000 for the Department to expand the existing modeling and simulation capabilities at the national laboratories to assess issues related to the aging and safety of storing spent nuclear fuel in fuel pools and dry storage casks. The Committee includes $60,000,000 for Used Nuclear Fuel Disposition, and directs the Department to focus research and development activities on the following priorities: $10,000,000 for development and licensing of standardized transportation, aging, and disposition canisters and casks; $3,000,000 for development of models for potential partnerships to manage spent nuclear fuel and high level waste; and $7,000,000 for characterization of potential geologic repository media.
  • “The Committee provides funding for evaluation of standardized transportation, aging and disposition cask and canister design, cost, and safety characteristics, in order to enable the Department to determine those that should be used if the Federal Government begins transporting fuel from reactor sites, as it is legally obligated to do, and consolidating fuel. The Committee notes that the Blue Ribbon Commission on America’s Nuclear Future has, in its draft report, recommended the creation of consolidated interim storage facilities, for which the Federal Government will need casks and canisters to transport and store spent fuel.

Huhne will use Fukushima report to revive nuclear programme [09Oct11] - 0 views

  • The government is expected this week to try to use a post-Fukushima green light from Britain’s chief nuclear safety inspector to inject momentum into its stuttering nuclear power and anti-climate-change programmes. The move will run into a hail of criticism from environmentalists who believe the latest inquiry into the nuclear industry has been rushed through and fear that ministers are backing off from their commitments to green issues. On Tuesday, Chris Huhne, the energy secretary, is scheduled to release the final report by Mike Weightman, chief inspector for nuclear installations, into what lessons should be learned from the Fukushima reactor disaster in Japan. The report is understood to contain only small amendments to an earlier, interim, report which made only minor recommendations.

UK:Nuke plan branded too hasty [09Oct11] - 0 views

  • Environmental campaigners have accused the Government of pushing ahead with new nuclear power plants in the wake of the Fukushima disaster. The Department Of Energy & Climate Change is publishing its final report into the implications for the UK’s nuclear industry following the crisis in Japan. But Greenpeace said it was concerned the inquiry had been conducted too quickly to learn the lessons from the tsunami-stricken plant. It said the Government had not even waited for the final report to be published before signalling the go-ahead for a new generation of nuclear plants this summer.

Differences in nuclear regulations [14Jul11] - 0 views

  • The U.S. Nuclear Regulatory Commission released recommendations this week based on lessons from Japan's Fukushima Daiichi nuclear plant disaster, declaring that events like those at Fukushima are unlikely to occur in the United States because of stringent safety measures and regulations.
  • The 90-day study suggested developing equipment and procedures for U.S. nuclear reactors to keep the core and spent fuel pool cool and requiring that facilities' emergency plans address prolonged station blackouts and events involving multiple reactors.

The battle for the atom is heating up again [21Jun11] - 0 views

  • I have been rereading a 1982 book by Bertrand Goldschmidt titled “The Atomic Complex: A Worldwide Political History of Nuclear Energy.”
  • The two self-assigned homework projects are as part of a reflective effort to understand more about how human society moved from a period of optimism based on a vision of “Atoms for Peace” to a period where someone reading the advertiser supported press would believe that sensible people would logically consider giving up the whole technology out of fear of radiation and its health consequences.One of the hopeful lessons I have learned so far is that the initial conditions of our current fight to defend and expand the safe use of atomic energy are far different from those that faced the people engaged in the earliest battles against a well organized opposition to nuclear technology development. We have a much better chance of success now than we did then – and there are several reasons why that is true.
  • One condition that is vastly different is the ability of nuclear professionals to have their voices heard. No longer are most people who understand nuclear energy isolated in small communities with few media outlets. In the 1970s, a large fraction of nuclear professionals were located near remotely sited national laboratories or power stations. Today, though many still work at national labs or in small market communities like Lynchburg, VA, we are all globally connected to a vast network on the Internet. We have Skype, YouTube and blogs. Some of us know that major decision makers and journalists read or listen to our words on a regular basis. We are no longer shy about responding to misinformation and unwarranted criticism.

  • For example, many of you have probably seen or read the Associated Press hit piece on the effort by the Nuclear Regulatory Commission and the nuclear industry to address the issue of aging nuclear power stations
  • The encouraging thing about that response is that it happened on the SAME DAY as the AP report was released. After Dan published his report, he notified the world via Twitter that the post was up. I have already had the opportunity to retweet his announcement and to share his link in a conversation related to a Huffington Post article titled U.S. Nuclear Regulators Weaken Safety Rules, Fail To Enforce Them: AP Investigation and in a conversation on Joe Romm’s Climate Progress titled AP Bombshell: U.S. Nuclear Regulators “Repeatedly” Weaken Safety Rules or are “Simply Failing to Enforce Them”.Think about that – it has been just 24 hours since the AP story hit the wires, yet nuclear professionals are already sharing a completely different side of the story without the filter of someone else deciding what is important.
  • However, the AP reporter, most likely someone who has never worked on an old car or repaired an old submarine, took a lot of stories out of context. He added a number of scary sounding inferences about the relationship between the regulators and the regulated. In response to the story, Dan Yurman, who blogs at Idaho Samizdat and was a professional journalist before he became a nuclear professional, reached out for real expertise.
  • He interviewed Dr. John Bickel, a man who has about 39 years worth of professional experience in plant aging, defense in depth and other safety related issues. You can read Dan’s excellent article at Associated Press Nukes the NRC on Reactor Safety.
  • It should be no secret to anyone that the average age of nuclear power plants in the US increases by almost exactly one year with every passing year. We are only officially building one plant right now, with four more that will enter that category as soon as the NRC issues the construction and operating licenses. It is also no secret that the NRC and the industry have been working hard to address aging as part of the effort to relicense plants for an additional 20 years, a process that is complete for more than 60 plants so far.
  • Another thing that is different about the fight over using atomic energy now, compared to the fight that happened in the late 1960s through the 1990s is that the opposition has a much less capable base of leaders. In the previous phase of the battle, the antinuclear movement grew out of a morally understandable effort to stop testing nuclear weapons in the earth’s atmosphere.
  • That effort was inspired by real world events like showering a Japanese fishing vessel with lethal doses of fallout from an ill-timed test in the middle of the Pacific ocean. It was led by some of the world’s most renowned atomic scientists, many of whom bore a deep moral guilt for their wartime efforts to build the Bomb in the first place.
  • When that effort succeeded in convincing the US, the UK and Russia to agree to stop atmospheric testing in 1963, some of the organizations that had been formed to do the heavy lifting saw substantial decreases in membership and contributions. After all, they could have easily hung up a large banner saying “Mission Accomplished” and closed up shop. Some did just that. Some persisted for a while with a variety of related issues like fighting against antiballistic missile installations and medium range rockets.
  • The groups organized against nuclear energy today are no longer led by world renowned scientists, though they do have some media celebrities with spotty professional histories and puffed up resumes. In many cases, they are grayer than I am and less well versed in the techniques of modern communications. Their fellow travelers on blogs and message boards routinely expose their own ignorance and sometimes their near illiteracy.
  • In contrast to the past, many of the renowned nuclear scientists and engineers in the profession today have no guilt at all. They did not participate in developing fearful weapons of mass destruction. Instead, they have spent their lives participating in an enterprise that provides massive quantities of emission free, low cost power to the people of the world. Seasoned professionals like Ted Rockwell, Margaret Harding, Meredith Angwin and Gail Marcus are out there blogging away and telling people what they know to be true about nuclear energy.
  • Enthusiastic younger people like Kirk Sorensen, Jack Gamble, and Suzy Hobbs are sharing optimistic visions for the future and explaining why they have chosen to support nuclear energy development, often in the face of numerous friends who disagree
  • I am encouraged. Atomic energy is alive and well; there is nothing that humans can do to eliminate its existence. We are entering a golden age of nuclear energy where facts and reality will overcome fictional tall tales spun by folks like Arnie Gundersen or Paul Blanche.

Sun and wind as alternative to nuclear energy : Voice of Russia [04Jul11] - 0 views

  • Scared by the nuclear disaster at the Japanese Fukushima-1 Nuclear power plant, Germany, Italy and Switzerland have decided to abandon nuclear energy towards alternative sources of energy. How safe are these alternatives?  Today ecologists and scientists are trying to answer this question.Nature protection activists call alternative sources of energy “green” sources. However after a more detailed study these sources can hardly be regarded as “environmentally friendly”. Silicon solar arrays Europeans want to see on the roofs of their houses turn to be unsafe right at the stage of their production. The production of one ton of photo elements leads to the emission up to 4 tons of silicon tetrachloride, a highly toxic substance, which combinations may cause different diseases. Besides poisonous gallium, lead and arsenic the photo elements also contain cadmium. If cadmium enters a human body it can cause tumors and affect the nervous system.
  • As for wind turbines, their noise is dangerous for health and it is impossible to recycle the worn blades. Though green energy sources are not completely safe it is the question of choosing the lesser of two evils, Igor Shkradyuk, the coordinator of the program on the greening of industrial activities at the Center of Wild Life Protection, says."Absolutely environmentally clean energy does not exist.  All its types have stronger of weaker impact on the environment. A solar battery requires a huge amount of unhealthy silicon. Engineers hope that silicon-free materials for solar batteries will be produced in 10-20 years. The solar battery, if you don’t break it, of course, poses no danger. As for wind turbines, the first one was put into operation in mid 1970-s in Germany. But the residents complained about its strong vibration and noise and a local court ruled to stop it. Since then many things have changed and modern powerful wind turbines are unheard already at a distance of 200 meters. But they are the main source of danger for migrating birds which are almost asleep as they fly to their wintering grounds and back."
  • Vladimir Chuprov, the head of the energy department of Russia’s Greenpeace agrees that all sources of energy cause environmental damage.  But the alternative sources have advantages anyway, he says."Of course, we are negative towards any pollution and here the problem of choice comes up. For example, silicon production requires chlorine which is hazardous. But now the gradual transition to chorine-free methods of silicon production has already begun.  Besides that we see the gradual transition to thin-film photoconverters in particular arsenic based converters. And after all, nobody says that solar batteries will be thrown to a dump site. It is necessary to ensure their proper utilization." 
  • ...1 more annotation...
  • The nuclear energy industry also faces serious upgrading. Russia has the project of constructing a nuclear power plant certified by the EU. This project takes into account all the tragic lessons of Fukushima. In particular such a plant will be capable to withstand the crash of an aircraft.Another problem of choice is the price. The energy from solar batteries and wind turbines is 2-5 times more expensive than that from nuclear energy. And while Germany is rejecting the use nuclear energy, France is proposing it to export its electricity produced by the French nuclear plants and China is ready to employ German experts in nuclear energy.

Des Moines Register: "Nuclear plants need scrutiny, not hysteria" [02Jul11] - 0 views

  • this is a June 29 Des Moines Register editorial, telling readers "Don't be irrational, don't be hysterical, and don't you dare be anti-nuke". And don't listen to those "baseless rumors": Nuclear plants need scrutiny, not hysteria "Right now the plants are safe."That's what the chairman of the U.S. Nuclear Regulatory Commission said of the two nuclear power plants along the Missouri River in Nebraska after recent flooding. There have been no "nuclear releases." Vital systems to ensure safety are protected. Flood waters are not expected to become unmanageable
  • Gov. Terry Branstad said that state officials are monitoring the plants and that the public should not worry.Yet some people worry
  • A healthy dose of concern about nuclear energy is necessary to help keep this country's power plants are safe. The United States must remain dedicated to rigorous scrutiny of plant safety regulations and emergency measures
  • ...5 more annotations...
  • This country has 104 nuclear power plants in 31 states, including Iowa. What's going on in Nebraska is a reminder of the need to ensure they are safe and there are plans in place to respond in the event of a natural or man-made disaster
  • They are also a reminder of the importance this country must place on protecting key areas -- including those with nuclear plants -- from flooding. While the U.S. must continue to focus on conservation and cultivating alternative sources of energy like wind, the reality is nuclear energy provides 20 percent of the nation's electricity. Along with coal, petroleum, natural gas and wind, it is an important part of this country's energy portfolio.
  • That portfolio must be more, not less, diverse. As the world has seen in Japan, a disrupted energy supply can lead to an economic crisis.Americans use a lot of energy. It has to come from somewhere, and providing it comes with risks. Yet we do not stop drilling for oil because there is an oil spill. We do not stop mining for coal because of a cave-in. We cannot allow fears about nuclear energy -- unfounded fears, as of now in Nebraska -- scare us away from this important power source
  • I particularly like the last three paragraphs
  • A disrupted energy supply in Japan is not because of nuclear power plant shutdowns, but because too many thermal and hydro power generating plants had been shut down. Rolling blackouts were intentional, to teach the Japanese the lesson - "nuclear power is necessary". Besides, an economic crisis is the last thing that ordinary people in Japan care about right now. (I don't know about the politicians and big power company execs.)

Royal Society calls for long-term nuclear plans [13Oct11] - 0 views

  • The government must establish long-term plans for a new generation of nuclear power plants so future generations are not left dealing with its legacy, experts urged on Thursday.Ministers must work with the industry to create a "holistic" strategy which deals effectively with reprocessing and disposal of spent nuclear fuel and does not treat it simply as "an afterthought", they warned.The new build programme must also take into account the UK's stockpile of civil plutonium - the largest in the world - created as a waste fuel from nuclear reactors but which can potentially be reprocessed into new nuclear fuel.
  • The warning comes as the government pushes ahead with a new generation of nuclear power stations in a bid to meet electricity demand and cut carbon emissions from the energy sector.In a report from the Royal Society, the group of experts said the handling of nuclear fuel throughout its working cycle must be considered to reduce security risks and the danger of proliferation of nuclear weapons.Research and development programmes are needed from the outset of the new build project to ensure fuel is managed properly, they added.Roger Cashmore, chairman of the Royal Society working group and head of the UK Atomic Energy Authority, said: "The last time any UK government articulated a coherent long-term plan for nuclear power was in 1955.
  • "We need to ensure that government and industry work together now to develop a long-term, holistic strategy for nuclear power in the UK."This must encompass the entire nuclear fuel cycle, from fresh fuel manufacture to disposal. Indeed, spent fuel can no longer be an afterthought and governments worldwide need to face up to this issue."He added: "While the government has made some positive moves towards an integrated approach to nuclear power, more must be done."The call comes after the energy secretary, Chris Huhne, signalled that a new generation of nuclear power plants would go ahead after a government-ordered review into the Fukushima disaster in Japan found no reason to curtail the use of reactors in the UK.

  • The review by chief nuclear inspector Mike Weightman examined the lessons that could be learned from the crisis at the Fukushima reactor when it was hit by a magnitude nine earthquake and subsequent tsunami in March.It revealed no "fundamental weaknesses" in the regulatory or safety assessment regimes of the UK nuclear industry, although it did outline 38 areas where improvements could be made.Prof Cashmore added: "Fukushima has shown that we cannot be complacent about the safety of nuclear power."However, the same principle must apply to nuclear security and non-proliferation. Both governments and the nuclear industry need to seriously reassess their responsibilities in these areas."

We may be too late to evacuate [15Oct11] - 0 views

  • In Chernobyl, 0.09 uSv/h → Children started having symptoms. (near radiation level as westen Tokyo) 0.16 uSv/h → Adults got leukemia within 5 years. (near radiation level as Adachiku) 0.232 uSv/h → Mandatory evacuation area in Cheronobyl. (near radiation level as Asakusa or Tokyo Disneyland) I received a lot of queries. I would like to add some more explanation to this. This is a lecture of Ms. Noro Mika, who runs the NPO “Bridge to Chernobyl”
  • Annotator’s comment: Because I believe that breast-feeding has a tremendous influence not only on nutrition, but also on the mental aspect; that’s why I hope that the mothers who are breast-feeding their children pay strict attention also to the their level of internal exposure and evacuate as soon as possible. Because the danger of the radioactive substances is known well enough, the world is watching the way Japan is dealing with the situation. A country which abandons its children and doesn’t value their lives is not a country worthy of trust.
  • In Chernobyl, an area 30 km from the nuclear plant, where the radiation level was 0.232 μSv/hour, was declared “no-entry zone”. In Chernobyl, in area where radiation levels were daily even 0.16 μSv/hour have been admitted as being dangerous, and in fact, adults got leukemia and died. Annotator: In case, in Kamakura, were I live, the level is 0.16 μSv/hour. Concerning the gamma dose rate in a certain spots one meter above the ground level, the radiation levels declared officially for Kamakura city are generally between 0.11〜0.14 μSv/hour. Radioactivity, in case of of iron, concrete, etc causes the oxidation and corrosion, but in humans accelerates the aging process and cause them sickness.

  • And the effects start appearing in 2~3 years. We didn’t understand from the beginning where the hot spots were. But after checking later the areas where a lot of children got sick, in Belarus probably the radioactive substances were easily carried by the wind because the flat level ground, but it became clear that in areas 20~30 km from the plant there were places contaminated about just as much as Chernobyl. Kamakura is about 300 kilos away from Fukushima in a straight line. Based on the results of the investigations made after the nuclear accident in Chernobyl, in Europe the fact of assuming that 800km from the nuclear plant might be contaminated has been made taken into consideration as a basic rule for safety.
  • In Chernobyl, because contaminated farm products were made served in school lunches, about 70% of the children suffered from various kinds of health damages. Those (health problems) were not limited to their generation, and when those children became parents their problems passed to their children too. Because radioactive substances have similarities with nutrients like calcium, the mammals will feed a lot of them to their babies. Radioactive substances get easily out of their bodies by milk – hence, there were many cases when after giving birth to their first baby, a large quantity of radioactive substances were passed to the (first born) child and the mother’s health improved, but those children had serious congenital disorders (became people with serious disabilities).
  • She has been visiting Chernobyl for 25 years and help children to accept in Hokkaido for one month etc.. Currently, the radiation levels in some parts of Kanto area are 3 mSv/year. Annotator’s comment: According to the Ministry of Education, Culture, Sports, Science and Technology, the numerical values announced by the local government prove only the emission of gamma rays. The iodine and the cesium decay while emitting beta rays. If we have to deal strictly with gamma rays emissions, the degree of contamination can be understood, but we can’t measure the level of individual external exposure. Besides, the numerical values detected at the monitoring posts are measured at 10m above the ground level or even more.
  • Besides, there is no country who would buy things from a country that loosens it’s standards. The gov and Tepco spread misinformation (misinform the population). They should think about requesting the farmers give up growing farming products which are contaminated, give them compensation, and provide them new and safe farmlands.
  • n case of Chernobyl, party members, doctors and a nurses, teachers could afford to evacuate, because they could keep sustaining themselves even if they moved, but the poor people could not afford to evacuate. The symptoms which appeared at children who remained were the following: Headache nosebleed diarrhea thyroid problems not growing taller hard to recover after catching a cold swelling of the lymphatic glands, easily get sick with pneumonia kidney pain renal cancer
  • [that I have a] (because while radioactivity leaves the body, the urinary tract is affected) pain in the back side of the knee arthralgia wounds that take a long time to cure asthma hair loss problems with their hair growing alteration in visual acuity poor appetite poor concentration fatigability/easily getting tired cardiac pain (cardialgia) low resistance to diseases. The school lessons were shortened to 25 minutes, and because their kidneys became week, there are primary school children who wet their beds.
  • Even after becoming adults, the following cases were recorded: increase of myocardial infarcts an increase in the nr of sudden deaths death of young people in their 30th Accumulation of cesium in heart – even if eliminate from their bodies it (cesium) enters the body again after eating being exempted from the military service for having small holes in their hearts Regarding their children, the following medical cases were recorded - Brain damage, proved by the fact that they were slow in eating their meals.
  • Mothers of many children who were different from the other normal children give them to adoption, even if they didn’t have renal surgery or health problems, or a handicap. This kind of things are happening. (Source) German Translation

IAEA team praises Japan after Fukushima visit [14Oct11] - 0 views

  • A team of experts from the International Atomic Energy Agency praised Japan on Friday for steps it has taken to reduce radiation exposure for the public, particularly children, near the crippled Fukushima Dai-ichi nuclear plant.During a nine-day trip, the IAEA team visited schools, farms and government offices outside the 20-mile (12-kilometer) exclusion zone surrounding the power plant, which was damaged by a March 11 earthquake and tsunami.In a preliminary report submitted to the government, the 12-member team said Japan had developed "an efficient program for remediation — allocating the necessary legal, financial and technological resources to bring relief to the people affected by the accident, with priority being given to children."
  • The report noted efforts to decontaminate schools and some 400 playgrounds — mostly by volunteers, many of them parents of students. Towns around the exclusion zone have begun washing down public areas and removing topsoil in parks and school yards.It was the U.N. atomic agency's second major mission to Japan since the nuclear crisis began. Its purpose was to assess Japan's strategy and plans to reduce radiation exposure in areas around Fukushima prefecture.
  • No one has died from radiation in the nuclear crisis, but concerns remain high over how the lingering contamination will affect Fukushima's youth. On Sunday, local doctors began a long-term survey of children in the region for thyroid abnormalities, a problem linked with radiation exposure.In Ukraine, more than 6,000 cases of thyroid cancer have been detected in people who were children or adolescents when they were exposed to high levels of fallout immediately after the 1986 Chernobyl nuclear disaster. Japan's nuclear safety agency has said the radiation that leaked from the Fukushima plant was about one-sixth of that released from Chernobyl.

  • Tero Tapio Varjoranta, deputy chief of the IAEA team, told a news conference in Tokyo that many of the Chernobyl cancer cases came from drinking milk that contained radioactive cesium, but that Japan's food controls in this area were in "very good order."The IAEA has "done a lot of work to learn the lessons from Chernobyl," he said.
  • The report also urged Japanese authorities to help the public focus on dose levels — the amount of radiation an individual is exposed to — rather than the contamination of certain areas or objects that could be far from the closest humans."Contamination means radioactivity somewhere. Dosage is how it affects me," Varjoranta explained.The team found Japan's radiation monitoring system was "very good, very extensive," said leader Juan Carlos Lentijo, adding that it would detect any dangerous spike in radiation.The Fukushima accident forced about 100,000 people living around the plant to be evacuated, and many now live in temporary homes or shelters, uncertain of when they will be able to return to their homes. Some Japanese officials say it could be years.

NTI: Global Security Newswire - Japan Ties Contaminated Location to Nuclear Crisis [24O... - 0 views

  • Japan on Sunday said cesium that is generating significant radioactivity at a location in China prefecture had likely been released from the damaged Fukushima atomic facility, the Japan Times reported (see GSN, Oct. 21). The six-reactor power plant was damaged by the March 11 earthquake and tsunami that left more than 20,000 people missing or dead in Japan. Radiation releases on a level not seen since the 1986 Chernobyl disaster forced the evacuation of about 80,000 residents from a 12-mile ring exclusion zone surrounding the site in Fukushima prefecture. A Sunday inspection by Japanese Science Ministry and Kashiwa city authorities located an area to which rainwater had likely been carrying contaminants from the plant. The city had previously played down the likelihood that the radioactive material had originated from the nuclear facility (Japan Times, Oct. 24). Fukushima prefecture on Thursday said two boys between 4 and 7 years old had received the highest levels of internal radiation contamination out of roughly 4,500 locals tested, Kyodo News reported. The contamination would amount to roughly three millisieverts of radiation over their lives and would not produce dangerous effects, officials said (Kyodo News/Mainichi Daily News, Oct. 21). The Japanese Forestry Agency indicated that as soon as November it would begin to test pollen from cedar flowers located in the evacuation zone for cesium contamination, the Yomiuri Shimbun reported on Monday (Yomiuri Shimbun, Oct. 24). The government's Science Ministry and Fisheries Agency are set to ramp up and broaden testing for radioactive materials in ocean water and marine produce, the Asahi Shimbun reported on Saturday (Asahi Shimbun, Oct. 22).

Japan's Kansai Elec first to submit reactor test result [28Oct11] - 0 views

  • Move is first step in long process before its restart* No reactors taken offline have been restarted since Fukushima crisis (Adds comment in paragraph 18-19)
  • Japan's Kansai Electric Power Co became the first utility to submit the result of a first-stage stress test on one of its nuclear reactors, the initial step in rebuilding public faith in atomic energy.No reactors taken offline for routine maintenance have been restarted since a massive earthquake and tsunami in March triggered reactor meltdowns and the world's worst radioactive material leakage in 25 years at Tokyo Electric Power Co's Fukushima Daiichi station in the northeast.Japan's government, urged by industry, would like to get some reactors running again to support the ailing economy and minimise the risk of a power crunch this winter. It is reviewing its energy policy, including the role of nuclear power and guidelines on its safety.
  • Several other nuclear operators are also preparing to report on stress tests, with Shikoku Electric Power Co , another highly nuclear reliant utility in the west, seen among the next candidates to do so.Kansai Electric, the country's second-biggest utility, this morning submitted to the trade ministry's Nuclear and Industrial Safety Agency (NISA) the results of stress tests on the No.3 reactor at its Ohi plant in Fukui prefecture.The Osaka-based utility, which serves the flagship factories of big electronics firms including Panasonic Corp and Sharp Corp , has said meeting winter power demand would be tough without the restart of the 1,180 megawatt unit.
  • ...5 more annotations...
  • But submission of the report is only the beginning of a long process before reactors can actually restart.Trade Minister Yukio Edano said on Friday it would take several months before Kansai can restart the unit.The stress tests evaluate each reactor's resilience against four severe events -- earthquake, tsunami, station blackout and loss of water for cooling -- and a reactor operator's management of multiple steps to protect reactors.
  • If there is any doubt on the basis of a reactor's safety assumptions, such as estimated standard earthquake ground motion, that should be discussed before giving approval to its stress test, said Tomoya Ichimura, director of NISA's safety regulatory standard division.The checks by NISA on each utility's assessments on a reactor would be followed by approval by the Nuclear Safety Commission of Japan, an independent entity which monitors relevant agencies including NISA.NISA will take into account test results for EU rectors, which are undergoing similar stress tests, with results due this month. It also plans to seek advice on the regulation process from the U.N. International Atomic Energy Agency.
  • Approval would then be needed from the prime minister and relevant ministers, as well as local governments."It is impossible to gauge mathematically the level of confidence (over the reactor restart) by local communities and our people. We, politicians, are responsible to make the judgement," Edano said.How to ensure safety for the first reactor to restart in the post-Fukushima era is being carefully watched at home and from abroad.
  • "Greenpeace is extremely concerned that this government is going to push through the restart of reactors without having learned the key lessons from what really went wrong in terms of organisation and crisis management during the Fukushima crisis," the international environmental group said in a statement after Kansai's stress test submission.An investigation is under way by government-appointed experts into the causes of the Fukushima incident, but it could take years to complete.Setsuko Kuroda, a woman from Koriyama city in Fukushima prefecture and one of dozens of those who protested against atomic power in front of the trade ministry on Friday, said restarting reactors while the Fukushima crisis continues is out of the question.
  • Why are they even saying this when the situation (at Fukushima) is still under such condition? Is the economy more important or are lives more important?" she questioned.Only 10 of Japan's 54 commercial reactors are currently online, as the Fukushima crisis and subsequent scandals have left communities reluctant to allow restarts.Then Prime Minister Naoto Kan in July introduced the stress tests as preconditions before idled reactors restart.First-stage tests are on idled reactors which are ready to restart and second-stage tests apply to all reactors.

Japan winter power enough despite nuclear lack: government | Reuters - 0 views

  • (Reuters) - Japanese utilities will largely avoid power shortages this winter despite prolonged reactor shutdowns amid public concerns over nuclear safety, but hurdles remain for next summer, the government said on Tuesday.
  • It also unveiled ways to bridge the gap next summer, when peak-hour demand is expected to exceed supply by 16,560 megawatts, compared with the biggest gap this winter of 2,530 MW in one area, if no reactors restart by then.
  • Utilities plan to secure additional fossil-fuel capacity of 4,090 MW by next summer, but other plans depend on how far policy initiatives, such as fiscal spending, can encourage energy conservation and the use of solar and wind power, leaving the risk of rolling blackouts.

  • Using gas and oil to make up for the loss of all nuclear power reactors will cost more than 3 trillion yen ($38 billion) a year, based on imported fuel prices and utilization rates in 2009, the government has estimated.
  • "Even if no reactors are restarted by next summer, the government would like to do its utmost through policy efforts to ensure we can meet peak-hour demand and avoid a rise in costs for energy," Trade Minister Yukio Edano said at a news conference after he and other ministers discussed chances of power shortages this winter and next summer.
  • The ongoing radiation crisis at Tokyo Electric Power Co's Fukushima Daiichi plant, triggered by the March earthquake and tsunami, has shaken public confidence in nuclear safety, forcing watchdogs to set stricter regulations for restarting reactors closed for regular checks.

Reactor in Japan Restarts, a First Since the Tsunami - NYTimes.com [01Nov11] - 0 views

  • Since the March 11 earthquake and tsunami that set off the nuclear disaster, a popular backlash against nuclear power has halted the reopening of reactors closed because of damage at the time or unrelated glitches, or for routine inspections. Regulations require reactors to close at least every 13 months for checks, meaning more and more reactors have gone out of service, with none allowed to restart — until Tuesday.
  • Only 10 of Japan’s 54 reactors are now generating electricity, a sharp reduction for an industry that once supplied 30 percent of the country’s electricity. The shortfall in supply forced the Tokyo Electric Power Company to tell companies to slash energy use by 15 percent this summer.
  • The government has been keen to soothe local jitters about nuclear energy and enable reactor restarts. But power companies must submit results of “stress tests” that evaluate a reactor’s defenses against earthquakes, tsunamis, station blackouts and the loss of water for cooling — and they must get a go-ahead from local the government.

  • Then early last month, a third reactor shut down at Genkai after a worker mistakenly pulled out a cable from the unit’s condenser vacuum, causing the turbine to stop. The full details of the case have not been made public.
  • Yasushi Furukawa, the governor of Saga Prefecture, has wavered on whether to allow restarting two idle reactors at the Genkai Nuclear Power Plant. Seen as a bellwether for the rest of Japan, Mr. Furukawa had appeared to be moving toward allowing two of the reactors to restart but his decision was put off after revelations of a scandal over faked supportive e-mails sent by employees of the local Kyushu Electric Power Company posing as pro-nuclear citizens.
  • Kyushu Electric called it a small error and said that the automatic shutdown it triggered had gone smoothly. But some critics warned that the episode constituted a serious safety lapse and pointed to a more widespread problem at other plants. Since then, however, the utility has submitted — and Japan’s nuclear regulators have checked and approved — operation manuals for that reactor, paving the way for a restart. “If this is a decision reached by the central government after ample checks, we accept,” Mr. Furukawa told reporters Tuesday before the restart. The reactor at the Genkai plant was started up around 11 p.m. local time and was set to reach 100 percent generating capacity on Wednesday, Kyushu Electric said. But the reactor’s run will be brief: the same reactor must be stopped in mid-December for routine maintenance.

Canadian regulators declare their nuclear plants safe in Post-Fukushima report [31Oct11] - 0 views

  • On Friday Canadian regulators published their post-Fukushima Daiichi report on nuclear safety, concluding the country’s reactors could stand up safely to the conditions that triggered the crisis in Japan. As in the United States, the Canadian government ordered inspections of its operating nuclear plants and a review of their accident preparedness in response to the March station blackout that severely damaged three reactors. The Canadian Nuclear Safety Commission’s Fukushima Task Force Report “concludes that Canadian nuclear power plants are safe and pose a very small risk to the health and safety of Canadians or to the environment.” The report identified no gaps in emergency planning or regulatory oversight related to severe accidents. Further, the CNSC said in a release the country’s reactors can “withstand conditions similar to those that triggered the Fukushima event.”
