Nuclear electricity: a fallen dream? [28Sep11] - 0 views

  • Nuclear power is no magic solution, argues Pervez Hoodbhoy — it's not safe, or cheap, and it leads to weapons programmes. A string of energy-starved developing countries have looked at nuclear power as the magic solution. No oil, no gas, no coal needed – it's a fuel with zero air pollution or carbon dioxide emissions. High-tech and prestigious, it was seen as relatively safe. But then Fukushima came along. The disaster's global psychological impact exceeded Chernobyl's, and left a world that's now unsure if nuclear electricity is the answe
  • Core concerns The fire that followed the failure of emergency generators at the Daiichi nuclear complex raised the terrifying prospect of radiation leaking and spreading. The core of the Unit 1 reactor melted, and spent nuclear fuel, stored under pools of water, sprang to life as cooling pumps stopped. Fukushima's nuclear reactors had been built to withstand the worst, including earthquakes and tsunamis. Sensors successfully shut down the reactors, but when a wall of water 30 feet high crashed over the 20-foot protective concrete walls, electrical power, essential for cooling, was lost. The plume of radiation reached as far as Canada. Closer, it was far worse. Japan knows that swathes of its territory will be contaminated, perhaps uninhabitable, for the rest of the century. In July, for example, beef, vegetables, and ocean fish sold in supermarkets were found to have radioactive caesium in doses several times the safe level. [1]
  • The Japanese have been careful. In the country of the hibakusha (surviving victims of Hiroshima and Nagasaki), all reactors go through closer scrutiny than anywhere else. But this clearly wasn't enough. Other highly developed countries — Canada, Russia, UK, and US — have also seen serious reactor accidents. What does this mean for a typical developing country? There, radiation dangers and reactor safety have yet to enter public debate. Regulatory mechanisms are strictly controlled by the authorities, citing national security reasons. And individuals or nongovernmental organisations are forbidden from monitoring radiation levels near any nuclear facility. Poor and powerless village communities in India and Pakistan, that have suffered health effects from uranium and thorium mining, have been forced to withdraw their court cases.

  • Is nuclear energy cost efficient? A 2009 Massachusetts Institute of Technology study, which strongly recommended enhancing the role of nuclear power to offset climate change [2], found that nuclear electricity costs more per kilowatt-hour (kWh): 8.4 cents versus 6.2/6.5 cents for coal/gas. It suggested that as fossil fuel depletes, the nuclear-fossil price ratio will turn around. But it hasn't yet. The World Bank has labelled nuclear plants "large white elephants". [3] Its Environmental Assessment Source Book says: "Nuclear plants are thus uneconomic because at present and projected costs they are unlikely to be the least-cost alternative.
  • The aftermath of a Fukushima-type incident might look very different in many developing countries. With volatile populations and little disaster management capability, the social response would probably be quite different. In Japan, tsunami survivors helped each other, relief teams operated unobstructed, and rescuers had full radiation protection gear. No panic, and no anti-government demonstrations followed the reactor explosions. Questions about cost
  • There is also evidence that the cost figures usually cited by suppliers are substantially underestimated and often fail to take adequately into account waste disposal, decommissioning, and other environmental costs." [4] According to the US Nuclear Regulatory Commission, the cost of permanently shutting down a reactor ranges from US$300 million to US$400 million. [5] This is a hefty fraction of the reactor's original cost (20–30 per cent). While countries like France or South Korea do find nuclear energy profitable, they may be exceptions to a general rule. Countries that lack engineering capacity to make their own reactors will pay more to import and operate the technology.
  • Poor track record, military ambitions The track record of nuclear power in developing countries scarcely inspires confidence. Take the case of Pakistan, which still experiences long, daily electricity blackouts. Forty years ago, the Pakistan Atomic Energy Commission had promised that the country's entire electricity demand would be met from nuclear reactors. Although the commission helped produce 100 nuclear bombs, and employs over 30,000 people, it has come nowhere close to meeting the electricity target. Two reactors combine to produce about 0.7 GW, which meets around 2 per cent of Pakistan's electricity consumption.
  • India's record is also less than stellar. In 1962, it announced that installed nuclear capacity would be 18–20 GW by 1987; but it could reach only 1.48 GW by that year. Today, only 2.7 per cent of India's electricity comes from nuclear fuels. In 1994, an accident during the construction of two reactors at the Kaiga Generating Station pushed up their cost to four times the initial estimate. Cost overruns and delays are frequent, not just in India. And some developing countries' interest in nuclear technology for energy could mask another purpose. India and Pakistan built their weapon-making capacity around their civilian nuclear infrastructure. They were not the first, and will not be the last.
  • Warning bells ring loud and clear when big oil-producing countries start looking to build nuclear plants. Iran, with the second largest petroleum reserves in the world, now stands at the threshold of making a bomb using low enriched uranium fuel prepared for its reactors. Saudi Arabia, a rival which will seek its bomb if Iran makes one, has plans to spend over US$300 billion to build 16 nuclear reactors over the next 20 years. Climate change gives urgency to finding non-fossil fuel energy alternatives. But making a convincing case for nuclear power is getting harder. Neither cheap nor safe, it faces an uphill battle. Unless there is a radical technical breakthrough — such as a workable reactor fuelled by nuclear fusion rather than nuclear fission — its prospects for growth look bleak. Pervez Hoodbhoy received his PhD in nuclear physics from the Massachusetts Institute of Technology, USA. He teaches at the School of Science and Engineering at LUMS (Lahore) and at Quaid-e-Azam University, Islamabad, Pakistan.

Va. Power hopes to restart reactors soon [08Sep11] - 0 views

  • Dominion Virginia Power thinks it will be ready to restart its North Anna 1 nuclear reactor in two weeks and the North Anna 2 by mid-October, if federal regulators approve. But the Nuclear Regulatory Commission staff members indicated Thursday that making sure the reactors, which were shut down by the Aug. 23 earthquake nearby, are safe to begin operating again might take longer. The staff said at the meeting with utility officials that it had plenty of questions as the agency looks into the Louisa County power station's design to resist seismic damage.
  • Preliminary information from the U.S. Geological Survey indicates that the earthquake produced a shaking force in the region twice as strong as the North Anna plant was designed to handle, the NRC said. Dominion Virginia Power acknowledges that the force from the earthquake exceeded the plant's theoretical design strength. The 5.8-magnitude earthquake caused only minor damage that did not affect nuclear safety, the company said. The quake also caused 25 of the 115-ton steel casks storing highly radioactive used fuel rods to shift as much as 4½ inches out of position on their concrete storage pad.
  • No U.S. nuclear power plant has been tripped off-line by an earthquake before, the NRC said.
  • ...8 more annotations...
  • We don't have a lot of experience in this area," said Eric J. Leeds, director of the NRC's Office of Nuclear Reactor Regulation. "It looks like we'll see a lot of each other over the next few weeks — hopefully not months."
  • Dominion Virginia Power is eager to get the plant, which can generate enough electricity to power 450,000 homes, operating again. The Richmond-based company is the state's largest electric utility, serving 2.3 million customers.
  • The NRC began assessing the safety implications of increased plant earthquake hazards in 2005. According to the agency, the potential earthquake hazards for some nuclear power plants in the central and eastern U.S. may be slightly larger than previously estimated.
  • The earthquake appears to have produced a peak acceleration — its shaking force — of about 0.26 g approximately 24 miles from its epicenter, the NRC said. G is the unit of measurement for acceleration based on the force of gravity. North Anna's rock-based structures are designed to withstand 0.12 g. The power station is about 11 miles from the quake's epicenter. The plant experienced earthquake forces an average of 21 percent greater than it was designed for, according to Dominion Virginia Power. The strong motion passed quickly, lasting no more than 3.1 seconds and reducing its impact, the company told NRC officials Thursday.
  • North Anna can handle shaking forces higher than 0.12 g in the critical lower frequencies, Dominion Virginia Power said. Most of the plant's critical safety components can actually resist shaking of 0.3 g, the company said, and relatively less-sturdy structures can withstand 0.16 g. "Consequently, safe shutdown components are capable of surviving seismic accelerations in excess of the … design criteria," Eric Hendrixson, Dominion Virginia Power's director of nuclear engineering, told federal regulators.
  • Based on results to date, Dominion Virginia Power believes all tests and repairs will be completed on Unit 1 by Sept. 22, said Eugene Grecheck, the company's vice president for nuclear development. Unit 2 is going into a planned refueling outage, and the company hopes it could be restarted by Oct. 13. But, warned Jack Grobe, deputy director of NRC's Office of Nuclear Reactor Regulation, "We're probably going to have to have a series of meetings. I guarantee you're going to get a lot of questions." Among the questions will be the shaking force of the earthquake on the plant.
  • Dominion Virginia Power still does not know exactly what caused the reactors to trip off-line, officials said Thursday. "There were diverse and redundant trips coming in in milliseconds," said N. Larry Lane, Dominion Virginia Power's site vice president for the power station.
  • Knowing precisely what prompted the shutdown is critical for validating the safety of the plant's design.

Federation of American Scientists :U.S. Leadership Essential for International Nuclear ... - 0 views

  • Global growth in the civilian nuclear energy sector represents an annual trade market estimated at $500 billion to $740 billion over the next 10 years.  As new nations consider nuclear energy technology to produce low-carbon electricity, the United States should take a leadership role that will enhance the safety and nuclear nonproliferation regimes globally, while creating tens of thousands of new American jobs. The United States is the world leader in safe and efficient operation of nuclear power plants, with an average capacity factor of 90 percent or higher in each of the past 10 years.  When ranked by 36-month unit capability factor, the United States has the top three best performing nuclear reactors in the world, seven of the top 10, and 16 of the top 20.  Nuclear energy facilities produce electricity in 31 states and have attained a four-fold improvement in safety during the past 20 years.  This underpinning in safety and reliability is one reason why America generates more electricity from nuclear energy than the next two largest nuclear programs combined.
  • Bilateral agreements on nuclear energy cooperation are vital to advancing global nonproliferation and safety goals as well as America’s interests in global nuclear energy trade.  A 123 agreement, named after section 123 of the Atomic Energy Act, establishes an accord for cooperation as a prerequisite for nuclear energy trade between the United States and other nations.  The agreement contains valuable nonproliferation controls and commitments.  One of the most significant elements of U.S. agreements is approval granted by our government as to how other countries process uranium fuel after it is used in a commercial reactor.  Under U.S. agreements, these nations cannot reprocess the fuel—chemically separating the uranium and plutonium—without U.S. notification and consent to do so.  This is a significant safeguard against the potential misuse of low-enriched uranium from the commercial sector.
  • Several public policy considerations must be weighed in evaluating the impact of 123 agreements, including those related to national security, economic development, energy production, and environmental protection. In the competitive global marketplace for commercial nuclear technology, inconsistent bilateral agreements will have unintended consequences for U.S. suppliers.  Imposing overly restrictive commercial restrictions or conditions in U.S. 123 agreements that are not matched by other nations’ bilateral agreements may significantly bias the country against selecting U.S.-based suppliers, even if the agreements don’t have malicious intentions. 
  • ...4 more annotations...
  • The imposition of requirements that seem unnecessary and unfair can affect commercial decision-making by the affected country.  Such conditions put U.S. commercial contracts and jobs at risk. Moreover, if the country does not use U.S.-based technology, fuels or services, the value of conditions in the 123 agreement (i.e., consent rights) would be lost. Some U.S. leaders are proposing a prohibition on uranium enrichment and reprocessing as part of all bilateral nuclear energy agreements for cooperation.  Ensuring enrichment technology and reprocessing technology are used only for peaceful purposes is a paramount goal for government and industry. But U.S. 123 agreements are neither the best, nor in most cases, the appropriate mechanism to achieve that goal. 
  • Multilateral agreements are more appropriate mechanisms for policy regarding the global challenge of nuclear proliferation.  Promising mechanisms include the decision by the International Atomic Energy Agency to establish a uranium fuel bank, potential nuclear fuel lease/takeback contracts, and other multilateral, institutional nonproliferation arrangements.  In addition, the Nuclear Suppliers Group (an international body of 46 nuclear technology supplier nations that sets standards for commercial nuclear trade) recently adopted new clear and strict criteria for the transfer of nuclear energy technology.  These institutional controls do not require the receiving country to cede sovereign rights, which the U.S. government and other countries with civilian nuclear energy programs would never give up. 
  • Fast-growing electricity needs in developing countries and concern about air quality and climate change are stimulating significant global demand for nuclear energy.  Sixty-six plants are being built worldwide and another 154 are in the licensing and advanced planning stage. U.S. suppliers are vying for business around the world – including China, Poland and India.  Continued U.S. leadership in global nuclear safety and nonproliferation matters go hand-in-hand with a strong presence in the global marketplace.  Both are critical to our national and global security.  We must continue to participate in worldwide trade and nonproliferation policy discussions, or cede leadership in these areas to other governments and industrial competitors.  Unless we choose engagement, America will lose tens of thousands of jobs and other benefits such trade has for our economy while forfeiting the nonproliferation benefits that 123 agreements are intended to achieve.

Today's plants far safer than Fukushima: US expert [14Sep11] - 1 views

  • The first of Fukushima Dai-ichi's six nuclear reactors came online in 1970, a full nine years before the Three-Mile Island crisis in the United States and 16 years before Chernobyl, the world's worst nuclear disaster. "The Fukushima plants were early plants, and so... more modern designs would be much more robust in their capability to deal with the situation" that Japan faced, said former US Nuclear Regulatory Commission chairman Richard Meserve. "Plants are much safer in their designs today." On March 11, a 9.0-magnitude quake rocked Fukushima, and the resulting 14-meter (46-foot) ocean wave drowned the plant, knocking out the power supply, the reactor cooling systems and back-up diesel generators.
  • Meserve said Fukushima's designers should have looked at historical data which showed a similar-sized tsunami hit the area in the year 869. The plant, he said, was designed to be able to accommodate a 5.7-meter tsunami. Meserve, an advisor to the UN's International Atomic Energy Agency, said plant developers in the United States always look at "what's the maximum probable event in that environment," and design accordingly. "It appears that this was not the case with regard to the Fukushima plant," he said. While its layout and design would not be considered by today's builders, Meserve stressed that Fukushima, for its day, was not seen as unsafe.
  • Designs have improved substantially in large part because engineers are "continuously learning from what has happened in the past and making sure that you learn from experience so that history is not repeated." Aside from advances like high-quality construction and passive safety systems that override human failures, today's designers incorporate what's known as "probabalistic risk assessment," which looks at the likelihood of events that could cause damage.

Fuku I Worker Who Pointed Finger at Livecam: Why He Did It, In His Own Words [05Oct11] - 0 views

  • My Requests and The Reasons Why I Pointed My Finger at TEPCO and the GovernmentI would like to request that TEPCO and the government improve in a tangible way how they contract work to subcontractors and how they monitor the employment situation.As has been much reported, some workers have been forced to work here by the outlaw element [i.e. "yakuza" or the Japanese mafia]. Such workers are disguised as being employed by legitimate contractors but have to accept an unfair or severe employment conditions. Sometimes even the legitimate contractors who post recruitment information at employment Offices don't know who their workers' true contractors are. The excessive multi-layered subcontracting leads to various problems such as lower wages, no insurance, and no contract document, as has been reported.In addition, I would like to share a few stories from my own experience
  • At the inn where I stayed, there were days when I could not sleep during the daytime before my nighttime shift, because my roommates' work shifts are different. Before work, the workers had to fill in the form to declare their health condition. On one of such sleep-starved days, I honestly declared that I had slept for 4 hours. But while I was looking away, one of my seniors rewrote it to 6 hours. I assume it was because workers who were not capable of managing their own health would put a bad face on the company.There is another problem. Even if we only worked for the prescribed hours, we had to spend huge amount of extra time taking care of the newcomers and registering them. Therefore, we sometimes ended up working or driving a car with only 1 or 2 hours of sleep.The subcontractors are competing with each other for more work and trying to show how much they could do even if they have to strain their workers a little. The contractors would benefit from the low-cost, high-efficiency work. However, by the very nature of the whole setup, minor troubles or problems will not be reported to the higher hierarchy. They are causing negative effects everywhere, and I am worried that they might eventually lead to a serious accident.

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.

Gemma Reguera on cleaning up nuclear waste with bacteria [03Oct11] - 0 views

  • Gemma Reguera at Michigan State University leads a team that found the normal digestive processes of a common type of bacteria – known as Geobacter – can reduce levels of uranium waste. She spoke with EarthSky:
  • geobacter
  • She said these bacteria don’t make radioactive material less radioactive. But they do immobilize it by converting it into a solid that’s more easily contained – so we can remove it and store it safely. Her group found that, when Geobacter come into contact with free-floating uranium – uranium dissolved in water, let’s say – the bacteria zap the uranium with small blasts of electricity. They do this naturally, as part of their digestive processes. This electricity causes the uranium to mineralize – in other words, they turn the uranium into something like a rock. Radioactive material is much less potent in this solid form, Reguera said, and easier to remove from the environment. She said:

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.
  • ...12 more annotations...
  • 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."

  • 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.

Japan Re-thinks its Energy Future. Nuclear Power Risks "too intense" [15Jul11] - 0 views

  • Saying that using nuclear power involves technology that is beyond the control of Japan’s conventional concept of safety, Kan said that following the disaster, he had come to realize that “the risk of nuclear energy is too intense. And while denying that he had called for an immediate stop to nuclear power, he did admit that previously chalked out plans that had aimed at increasing Japan’s use of nuclear to 50 percent by 2030 had been scrapped.
  • Nuclear Energy Worldwide
  • Germany derives 23% of its power from its 17 reactors. Calling the nuclear disaster and radiation leaks that took place in Japan a “catastrophe of apocalyptic dimensions”, Germany announced, in the latter part of March, that they would be looking at completely replacing energy produced by these nuclear power plants with renewable sources. Around the same time, Italy declared that they would be suspending their plans to revive nuclear energy for a year given the scale of radiation leaks that took place at the Fukushima reactors. Nuclear policies of India and China, the world’s two most populous nations, which had elaborate plans of expanding nuclear power capabilities, were also left shaken, with many experts stating that it would be difficult to get these countries to go ahead with expanding nuclear power facilities following the Japan disaster.

  • India had declared plans of spending $175 billion by 2030 on nuclear generation. In December, India had signed an agreement with France last December, which assigned $9.3 billion towards building two nuclear plants with the help of Areva, a Paris-based company. However, following the earthquake, concerned officials said that they would need to “revisit the entire thing” including their plans for setting up the new reactor plans.

TEPCO checking for gas leak from No.3 reactor [16Jul11] - 0 views

  • The operator of the Fukushima Daiichi nuclear power plant is checking for gas leaks in the No. 3 reactor, into which nitrogen is being injected to prevent a hydrogen explosion. Tokyo Electric Power Company has injected more than 200 cubic meters of nitrogen into the reactor's containment vessel since Thursday evening. But it says the interior air pressure has increased very little. TEPCO says gas may be leaking from a damaged part of the container. Also on Friday, TEPCO restarted a system for decontaminating highly radioactive water after a 9-hour stoppage to vent air from a pipe that was slowing down operations. But it says the system's capability is still more than 20 percent lower than the target figure. Nitrogen injection and the operation of the water decontamination system are essential for TEPCO to complete the first step of its plan to bring the plant under control. The utility is still suffering 1 problem after another, with just 2 days left before the first target date of July 17th. Friday, July 15, 2011 20:14 +

Magnox waste contract for Babcock [11Feb11] - 0 views

  • Babcock has been awarded a framework contract for the management of intermediate-level waste (ILW) at all of the UK's Magnox plant sites.
  • It and five other companies will bid for portions of a £300 million ($480 million) work program.
  • The owner of the UK's Magnox plants, the Nuclear Decommissioning Authority (NDA), has mandated the implementation of the 'Mini Store' option of managing its ILW. Under this option - which is more cost-effective than other options - the waste is placed in cast iron, self-shielding boxes weighing 18 tonnes and capable of holding almost three cubic-metres of waste. A concrete waste store approach had previously been chosen.

1 MW E-Cat Cold Fusion Device Test Successful [28Oct11] - 0 views

  • Well, the big day has come and gone. Andrea Rossi's one-megawatt-capable E-Cat cold fusion device has been tested in Bologna, Italy; and the unknown customer, who ran the test, is apparently happy.
  • There were some issues, so it couldn't be run at full power in self-looped mode, but what it did do was plenty impressive.
  • It ran for 5.5 hours producing 479 kW, while in self-looped mode. That means no substantial external energy was required to make it run, because it kept itself running, even while producing an excess of nearly half a megawatt. Rossi explained the reasons for this in the presentation he gave, which I videotaped and will be posting later.

  • That's half the rated capacity, but it is still a major accomplishment for the device that was completed earlier this week -- the first of its kind on the planet.

UCS Nuclear Power Safety & Security Recommendations | Union of Concerned Scientists [14... - 0 views

  • Download: U.S. Nuclear Power after Fukushima | U.S. Nuclear Power after Fukushima -- Summary
  • The report outlines and explains 23 specific recommendations, listed below.   = Key recommendation that the NRC should make a top priority. Preventing and Mitigating the Effects of Severe Accidents Extend the scope of regulations to include the prevention and mitigation of severe accidents. Require reactor owners to develop and test emergency procedures for situations when no AC or DC power is available for an extended period. Modify emergency planning requirements to ensure that everyone at significant risk from a severe accident--not just the people within the arbitrary 10-mile planning zone--is protected.
  • Improving the Safety and Security of Spent Fuel The NRC should require plant owners to move spent fuel at reactor sites from storage pools to dry casks when it has cooled enough to do so. The NRC should require reactor owners to improve the security of existing dry cask storage facilities. The NRC should require plant owners to significantly improve emergency procedures and operator training for spent fuel pool accidents Making Existing Reactors Safer The NRC should enforce its fire protection regulations and compel the owners of more than three dozen reactors to comply with regulations they currently violate.
  • ...2 more annotations...
  • Making Existing Reactors More Secure against Terrorist Attacks The NRC should revise its assumptions about terrorists' capabilities to ensure nuclear plants are adequately protected against credible threats, and these assumptions should be reviewed by U.S. intelligence agencies. The NRC should modify the way it judges force-on-force security exercises by assessing a plant's "margin to failure," rather than whether the plant merely passes or fails. The U.S. government should establish a program for licensing private security guards that would require successful completion of a federally supervised training course and periodic recertification. Making New Reactors More Secure against Terrrorist Attacks The NRC should require new reactor designs to be safer than existing reactors. The NRC should require new reactor designs to be more secure against land- and water-based terrorist attacks.
  • Improving the NRC's Cost-Benefit and Risk-Informed Analyses The NRC should increase the value it assigns to a human life in its cost-benefit analyses so the value is consistent with other government agencies. The NRC should require plant owners to calculcate the risk of fuel damage in spent fuel pools as well as reactor cores in all safety analyses. The NRC should not make decisions about reactor safety using probabilistic risk assessments (PRAs) until it has corrected its flawed application of this tool. Ensuring Public Participation The NRC should fully restore the public's right to obtain information and question witnesses in hearings about changes to existing power plant licenses and applications for new licenses.

U.S. Industry Taking Steps to Learn Lessons from Japan, Enhance Safety at America's Nuc... - 0 views

  • The nuclear energy industry will continue to work with the Nuclear Regulatory Commission as it considers forthcoming recommendations of an agency task force on new procedures and regulations in light of the accident at Fukushima Daiichi.  We have undertaken significant work in the past 90 days to examine our facilities and take the steps necessary to enhance safety.  We will continue to work with the Nuclear Regulatory Commission to understand any potential gaps in safety and fill those gaps. Prompted by the Fukushima accident, the NRC staff has been developing recommendations to enhance safety at America’s reactors. The task force is expected to release its report to the NRC commissioners within the next week. In their interim reports, NRC officials have emphasized that issues identified during the recent inspections will not impede the facilities’ ability to maintain safety even in the face of extreme events.
  • These NRC’s inspections complement industry efforts begun within days of the Fukushima Daiichi accident. Each of the nation’s 104 nuclear energy facilities has been subjected to a comprehensive verification of preparedness to maintain safety during a severe event, regardless of the cause. As a result of these self-inspections, facility operators have made immediate enhancements or developed plans to enhance safety. The vast majority of the items identified by the industry are enhancements to safety measures already in place.
  • The NRC has also made clear that issues identified during its post-Fukushima inspections at each plant do not undermine any facility’s ability to respond to extreme events. This conclusion is based upon exemplary levels of safe operation and the multiple layers of protection that exist at each nuclear energy facility in the country.   Moreover, in its annual reports to Congress, the NRC has listed only one “abnormal occurrence” over the past decade—an incident nine years ago that did not result in the release of radiation. Over the last 10 years, the NRC has not identified any negative trends in safety at America’s nuclear facilities. In the wake of the tragedy in Japan, Americans are concerned about whether U.S. reactors face the same risks.  The fact is, American nuclear facilities are subject to more regulatory scrutiny and requirements than in any other country.  American nuclear energy facilities are equipped and employees are trained to manage severe events. Since the terrorist attacks of Sept. 11, 2001, the industry has made significant improvements in physical structures and emergency response capabilities.

  • Commitment to Continuous Learning, Safety
  • The U.S. industry—through its commitment to continuous learning and relentless pursuit of excellence in safe operations—has taken significant action to ensure that American reactors are operated safety and securely. This includes actions in the following areas: Command and control: key operational and response decisions remain with shift supervisor—Decision-making remains on site with licensed operators. Reactor operators drill on accident scenarios several times each year and are prepared to respond to a wide range of potential severe events.
  • Operator licensing and training—U.S. reactor operators are licensed by the NRC and must re-qualify for their license every two years. U.S. reactor operators spend one week out of six in simulator training, which is more continuous training than pilots and doctors. Safety culture—The industry’s safety culture is transparent and encourages and facilitates the reporting of problems or concerns by employees through several channels. A commitment to safety culture is evidenced by employees who embrace continuous learning and maintain a questioning attitude regarding safety. This attitude gives rise to tools like corrective actions programs.
  • Independent regulator that includes resident inspectors—The NRC is an independent agency whose sole mission is protection of public health and safety. NRC inspectors located at each of America’s nuclear energy facilities have unfettered access to workers and data as part of their daily inspections. Creation of the Institute of Nuclear Power Operations—INPO was formed by the industry after the Three Mile Island accident to drive industry toward operational excellence and above and beyond NRC requirements. Post 9/11 security contingency measures—The NRC and industry took several actions after 9/11 to enhance security at America’s nuclear energy facilities. These features also would help mitigate extreme events, such as large fires or explosions.

Intelligent absorbent removes radioactive material from water 01Nov11[ - 0 views

  • Nuclear power plants are located close to sources of water, which is used as a coolant to handle the waste heat discharged by the plants. This means that water contaminated with radioactive material is often one of the problems to arise after a nuclear disaster. Researchers at Australia's Queensland University of Technology (QUT) have now developed what they say is a world-first intelligent absorbent that is capable of removing radioactive material from large amounts of contaminated water, resulting in clean water and concentrated waste that can be stored more efficiently. The new absorbent, which was developed by a QUT research team led by Professor Huai-Yong Zhu working in collaboration with the Australian Nuclear Science and Technology Organisation (ANSTO) and Pennsylvania State University, uses titanate nanofiber and nanotube technology. Unlike current clean-up methods, such as a layered clays and zeolites, the new material is able to efficiently lock in deadly radioactive material from contaminated water and the used absorbents can then be safely disposed of without the risk of leakage - even if the material were to become wet.
  • When the contaminated water is run through the fine nanotubes and fibers, the radioactive Cesium (Cs+) ions are trapped through a structural change. Additionally, by adding silver oxide nanocrystals to the outer surface, the nanostructures are able to capture and immobilize radioactive iodine (I-) ions used in treatments for thyroid cancer, in probes and markers for medical diagnosis, and also found in leaks of nuclear accidents. "One gram of the nanofibres can effectively purify at least one ton of polluted water," Professor Zhu said. "This saves large amounts of dangerous water needing to be stored somewhere and also prevents the risk of contaminated products leaking into the soil." "Australia is one of the largest producers of titania that are the raw materials used for fabricating the absorbents of titanate nanofibres and nanotubes. Now with the knowledge to produce the adsorbents, we have the technology to do the cleaning up for the world," added Professor Zhu.

BP gets Gulf oil drilling permit amid 28,000 unmonitored abandoned wells [25Oct11] - 0 views

  • Since BP’s catastrophic Macondo Blowout in the Gulf of Mexico last year, the Obama Administration has granted nearly 300 new drilling permits [1] and shirked plans to plug 3,600 of more than 28,000 abandoned wells, which pose significant threats to the severely damaged sea. Among those granted new permits for drilling in the Gulf, on Friday Obama granted BP permission to explore for oil in the Gulf, allowing it to bid on new leases that will be sold at auction in December. Reports Dow Jones: “The upcoming lease sale, scheduled for Dec. 14 in New Orleans, involves leases in the western Gulf of Mexico. The leases cover about 21 million acres, in water depths of up to 11,000 feet. It will be the first lease auction since the Deepwater Horizon spill.” [2]
  • Massachusetts Rep. Ed Markey objected to BP’s participation in the upcoming lease sale, pointing out that: “Comprehensive safety legislation hasn’t passed Congress, and BP hasn’t paid the fines they owe for their spill, yet BP is being given back the keys to drill in the Gulf.” Environmental watchdog, Oceana, added its objection to the new permits, saying that none of the new rules implemented since April 2010 would have prevented the BP disaster. “Our analysis shows that while the new rules may increase safety to some degree, they likely would not have prevented the last major oil spill, and similarly do not adequately protect against future ones.” [3]
  • Detailing the failure of the Dept. of Interior’s safety management systems, Oceana summarizes: Regulation exemptions (“departures”) are often granted, including one that arguably led to the BP blowout; Economic incentives make violating rules lucrative because penalties are ridiculously small; Blowout preventers continue to have critical deficiencies; and Oversight and inspection levels are paltry relative to the scale of drilling operation. Nor have any drilling permits been denied [4] since the BP catastrophe on April 20, 2010, which still spews oil today [5].

  • 28,079 Abandoned Wells in Gulf of Mexico In an explosive report at Sky Truth, John Amos reveals from government data that “there are currently 24,486 known permanently abandoned wells in the Gulf of Mexico, and 3,593 ‘temporarily’ abandoned wells, as of October 2011.” [6] TA wells are those temporarily sealed so that future drilling can be re-started. Both TA wells and “permanently abandoned” (PA) wells endure no inspections.
  • Not only cement, but seals, valves and gaskets can deteriorate over time. A 2000 report by C-FER Technologies to the Dept. of Interior identified several  different points where well leaks can occur, as this image (p. 26) reveals.  To date, no regulations prescribe a maximum time wells may remain inactive before being permanently abandoned. [13] “The most common failure mechanisms (corrosion, deterioration, and malfunction) cause mainly small leaks [up to 49 barrels, or 2,058 gallons]. Corrosion is historically known to cause 85% to 90% of small leaks.” Depending on various factors, C-FER concludes that “Shut-In” wells reach an environmental risk threshhold in six months, TA wells in about 10-12 years, and PA wells in 25 years.  Some of these abandoned wells are 63 years old.
  • Leaking abandoned wells pose a significant environmental and economic threat. A three-month EcoHearth investigation revealed that a minimum of 2.5 million abandoned wells in the US and 20-30 million worldwide receive no follow up inspections to ensure they are not leaking. Worse: “There is no known technology for securely sealing these tens of millions of abandoned wells. Many—likely hundreds of thousands—are already hemorrhaging oil, brine and greenhouse gases into the environment. Habitats are being fundamentally altered. Aquifers are being destroyed. Some of these abandoned wells are explosive, capable of building-leveling, toxin-spreading detonations. And thanks to primitive capping technologies, virtually all are leaking now—or will be.” [11] Sealed with cement, adds EcoHearth, “Each abandoned well is an environmental disaster waiting to happen. The triggers include accidents, earthquakes, natural erosion, re-pressurization (either spontaneous or precipitated by fracking) and, simply, time.”
  • Over a year ago, the Dept. of Interior promised to plug the “temporarily abandoned” (TA) wells, and dismantle another 650 production platforms no longer in use. [7] At an estimated decommissioning cost of $1-3 billion [8], none of this work has been started, though Feds have approved 912 permanent abandonment plans and 214 temporary abandonment plans submitted since its September 2010 rule. [9] Over 600 of those abandoned wells belong to BP, reported the Associated Press last year, adding that some of the permanently abandoned wells date back to the 1940s [10].  Amos advises that some of the “temporarily abandoned” wells date back to the 1950s. “Experts say abandoned wells can repressurize, much like a dormant volcano can awaken. And years of exposure to sea water and underground pressure can cause cementing and piping to corrode and weaken,” reports AP.
  • As far back as 1994, the Government Accountability Office warned that there was no effective strategy in place to inspect abandoned wells, nor were bonds sufficient to cover the cost of abandonment. Lease abandonment costs estimated at “$4.4 billion in current dollars … were covered by only $68 million in bonds.” [12] The GAO concluded that “leaks can occur… causing serious damage to the environment and marine life,” adding that “MMS has not encouraged the development of nonexplosive structure removal technologies that would eliminate or minimize environmental damage.”
  • The AP noted that none of the 1994 GAO recommendations have been implemented. Abandoned wells remain uninspected and pose a threat which the government continues to ignore. Agency Reorganization The Minerals Management Service (MMS) was renamed the Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE) last May after MMS drew heavy fire for malfeasance, including allowing exemptions to safety rules it granted to BP. An Office of Inspector General investigation revealed that MMS employees accepted gifts from the oil and gas industry, including sex, drugs and trips, and falsified inspection reports. [14] Not only was nothing was done with the 1994 GAO recommendations to protect the environment from abandoned wells, its 2003 reorganization recommendations [15] were likewise ignored.  In a June 2011 report on agency reorganization in the aftermath of the Gulf oil spill, the GAO reports that “as of December 2010,” the DOI “had not implemented many recommendations we made to address numerous weaknesses and challenges.” [16] Reorganization proceeded.  Effective October 1, 2011, the Dept. of the Interior split BOEMRE into three new federal agencies: the Office of Natural Resources Revenue to collect mineral leasing fees, the Bureau of Safety and Environmental Enforcement (BSEE) and the Bureau of Ocean Energy Management (BOEM) “to carry out the offshore energy management and safety and environmental oversight missions.” The DOI admits:
  • “The Deepwater Horizon blowout and resulting oil spill shed light on weaknesses in the federal offshore energy regulatory system, including the overly broad mandate and inherently conflicted missions of MMS which was charged with resource management, safety and environmental protection, and revenue collection.” [17] BOEM essentially manages the development of offshore drilling, while BSEE oversees environmental protection, with some eco-protection overlap between the two agencies. [18] Early this month, BSEE Director Michael R. Bromwich spoke at the Global Offshore Safety Summit Conference in Stavanger, Norway, sponsored by the International Regulators Forum. He announced a new position, Chief Environmental Officer of the BOEM:
  • This person will be empowered, at the national level, to make decisions and final recommendations when leasing and environmental program heads cannot reach agreement. This individual will also be a major participant in setting the scientific agenda for the United States’ oceans.” [19] Bromwich failed to mention anything about the abandoned wells under his purview. Out of sight, out of mind. Cost of the Macondo Blowout
  • On Monday, the GAO published its final report of a three-part series on the Gulf oil disaster. [20]  Focused on federal financial exposure to oil spill claims, the accountants nevertheless point out that, as of May 2011, BP paid $700 million toward those spill claims out of its $20 billion Trust established to cover that deadly accident. BP and Oxford Economics estimate the total cost for eco-cleanup and compensatory economic damages will run to the “tens of billions of dollars.” [21] On the taxpayer side, the GAO estimates the federal government’s costs will exceed the billion dollar incident cap set by the Oil Pollution Act of 1990 (as amended). As of May 2011, agency costs reached past $626 million. The Oil Spill Liability Trust Fund’s income is generated from an oil barrel tax that is set to expire in 2017, notes GAO.
  • With Monday’s District Court decision in Louisiana, BP also faces punitive damages on “thousands of thousands of thousands of claims.” U.S. District Judge Carl Barbier denied BP’s appeal that might have killed several hundred thousand claims, among them that clean up workers have still not been fully paid by BP. [22] Meanwhile, destroying the planet for profit continues unabated. It’s time to Occupy the Gulf of Mexico: No more oil drilling in our food source.

Swedish focus on earthquake protection [04Nov11] - 0 views

  • Swedish nuclear power plant operators will incorporate improvements highlighted by stress tests with a pre-existing program to standardise safety in earthquake scenarios. 
  • Some 34 countries are participating in a project led by the European Commission to put nuclear power plants through paper-based analyses where they are subjected to extreme circumstances and events such as natural disasters. The aim is to find the ultimate resilience of procedures and safety engineering and identify any 'cliff-edge' effects where the loss of a certain system may make a serious accident unavoidable.   On a common schedule, many of the countries have in recent days confirmed that their nuclear power plants are properly sited, designed and managed. However, a statement from the Swedish Radiation Safety Authority (SSM) frankly pointed out that: "What we can already see is that some plants do not fully meet requirements in the case of earthquakes. Here we will need to take action."   Jan Hanberg, SSM's head of radiation protection who led the stress test program, explained to World Nuclear News that there were no specific earthquake requirements in the early days of the Swedish nuclear program. The country relied on the intrinsic strength of each design in scenarios of strong earthquakes, which are highly unlikely due to Sweden's geology. Of the country's ten reactors, only Oskarshamn 3 and Forsmark 3 were licensed to specific earthquake resistance standards.
  • This potential gap in safety was addressed during 2005 by new earthquake-specific regulation imposed in a way that gave operators until 2013 to ensure their existing plants met requirements. Stress tests, however, had to be conducted based on the plant status as of 1 July this year. Hanberg told WNN that nuclear plant operators will continue to work towards the 2013 deadline, but may introduce additional safety measures in light of what has been learned through the stress tests. That may require a revision of the 2013 deadline, he said, depending on the programs of work agreed by SSM and the operators over the next month.   Some work will also be needed to ensure safety in scenarios involving a site with multiple reactors challenged simultaneously. SSM wants to be certain there will be sufficient command, control and fire-fighting capability.   Separately, SSM noted that Swedish nuclear power plants have excellent protection against radioactive release during accident scenarios. As part of learning from the 1979 accident at Three Mile Island in the USA all Swedish nuclear power plants were required to have filters to reduce the amount of radioactive material that would be released in an accident.
