U.N. nuclear safety proposals weakened: diplomats [30Aug11] - 0 views

  • Countries with atomic power plants would be encouraged to host international safety review missions, under a draft U.N. action plan that may disappoint those who had hoped for strong measures to prevent a repeat of Japan's nuclear crisis.
  • Seeking the middle ground between states advocating more binding global rules and others wanting to keep safety as a strictly national responsibility, the U.N. nuclear agency appears to have gradually watered down its own proposals.The document from the International Atomic Energy Agency, the third draft presented to IAEA member states over the last few weeks, outlines a series of steps to help improve nuclear safety after the Fukushima accident almost six months ago.
  • The latest version puts increased emphasis on the voluntary nature of the proposals, highlighting resistance among many countries against any move toward mandatory outside inspections of their nuclear energy installations.The changes were made following feedback from member state diplomats of the Vienna-based U.N. body. The 35-nation board of the IAEA is expected to debate the final proposal at a September 12-16 meeting in the Austrian capital.

  • "There has been a weakening," one European diplomat said of the latest draft, dated August 29 and obtained by Reuters on Tuesday. "We are a bit disappointed."Another diplomat from a Western country that also wanted firmer action said: "As thoughts of Fukushima fade slightly, people are less willing to take more concerted action."Japan's emergency prompted a rethink of energy policy worldwide, underlined by Germany's decision to close all its reactors by 2022 and Italy's vote to ban nuclear power for decades.

Acute lymphatic leukemia news caster Otsuka may die in 5 years for 70% [24Nov11] - 0 views

  • Following up to our previous post “JP Gov officially admitted that Japanese food is harmful” Mr. Otsuka Norikazu turned out to have acute lymphatic leukemia. Since 311, he has been “supporting north Japan by eating their food”. The connection between his patriotism and acute lymphatic leukemia is not clear, but German TV introduces like this. German TV piece He declared that he will be back on TV by next March or April, but he has his neck connected to the tube, and they are injecting anticancer drug. Now he is 63 years old. Statistically, even though he goes though the hard time to fight against cancer, the chance of surviving is 30~40% in 5 years. All we could do is to wish him the best luck.

Staff Tells N.R.C. That U.S. Rules Need Overhaul After Fukushima [18Jul11] - 1 views

  • The Nuclear Regulatory Commission’s rules are a patchwork that needs to be reorganized and integrated into a new structure to improve safety, the agency’s staff told the five members of the commission on Tuesday at a meeting.The session was called to consider reforms after a tsunami caused the triple meltdown at the Fukushima Daiichi nuclear plant in Japan. But how speedily the commission will take up the recommendations is not clear.
  • After the terrorist attacks of Sept. 11, 2011, the nuclear industry agreed to bring in assorted extra equipment, including batteries and generators, to cope with circumstances beyond what the plants were designed for. Such preparations are among the reasons that the commission has suggested that American reactors are better protected than Fukushima was. But back then, because their focus was on a potential terrorist attack, much of that equipment was located in spots that were not protected against floods, staff officials said.
  • “The insight that we drew from that is that if you make these decisions in a more holistic way, and you are more cognizant of what kinds of protections you are trying to foster, perhaps you can do them in a more useful way,’’ Gary Holahan, a member of the staff task force that reported to the commission, said on Tuesday. Another likely area of restructuring is to review the distinction that the commission makes between “design basis” and “beyond design basis” accidents. In the 1960s and 1970s, when the commission and a predecessor agency, the Atomic Energy Commission, issued construction permits for the 104 commercial reactors now running, they established requirements for hardware and training based on the safety factors arising from the characteristics of each site, including its vulnerability to flood or earthquake. Those are known as design-basis accidents.A variety of additional requirements involving potential problems that would be more severe but less likely (beyond design-basis accidents) have been added over the years.
  • ...2 more annotations...
  • Yet much more is known today about quake vulnerability, the potential for flooding and other safety factors than when many plants were designed. As a result, according to the task force’s report, sometimes two adjacent reactors that were designed at different times will apply different assumptions about the biggest natural hazard they face.One of the study’s recommendations is that the reactors be periodically re-evaluated for hazards like floods and earthquakes.
  • There are a dozen recommendations in all. The commission’s chairman, Gregory B. Jaczko, said the five commissioners should decide within 90 days (the same period it took to develop the recommendations) whether to accept or reject them, although actually acting on them would take far longer.

Is there a big crack in the ground at Fukushima?[02Aug11] - 1 views

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

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.

Returnees fear Fukushima's invisible touch [08Dec11] - 0 views

  • MINAMISOMA, Japan - The lugubrious notes of Silent Night wafted from an outdoor sound system on the near-empty main street to the station of this coastal city on the northern edge of the 20-kilometer "exclusion zone" around the Fukushima Daiichi nuclear power plant.
  • At a factory that salvages old and wrecked cars just outside the barriers on the road down the coast to the plant, a digital display in the office flashed the numbers -0.10 and 0.22 - highs and lows of micro-sieverts. "That’s well within the safety limit," a young woman in the factory's overseas marketing department assured me. "We are safe here." For all such assurances, though, nobody really believes bad stuff <a href='http://asianmedia.com/GAAN/www/delivery/ck.php?n=a53e495a&cb=INSERT_RANDOM_NUMBER_HERE' target='_blank'> <img src='http://asianmedia.com/GAAN/www/delivery/avw.php?zoneid=36&cb=INSERT_RANDOM_NUMBER_HERE&n=a53e495a' border='0' alt=''></a>  is no longer floating through the clear cold air or lapping up on the innocent looking shores beyond the concrete breakwater over which 40-foot waves surged that day, wiping out an entire district down the slope from the factory.
  • Radioactive substances come from the ground, from the river bottom."
  • ...7 more annotations...
  • Uncertain reports daily fuel the fears. One day people hear of a leak through which radioactive water is pouring into the sea, poisoning the fish that are a staple of everyone's diet. Next, there are stories of emissions of radioactive xenon gas and then a reading of radioactive cesium in powdered milk - enough for the Meiji Company to recall 400,000 cans of it this week "so people can feel their infants are safe".
  • At City Hall, Koshin Ogai, a young tax official, shared his fears. Ogai, originally from Osaka in western Japan, moved here a few years ago after marrying a local woman but sent his wife and their two children to his parents after explosions at the Fukushima first spread the fear of radiation. "I don't permit them to come back," he said. "I don't think the record here is safe." But what about all those assurances about the levels of radioactivity having fallen well within safe limits, I asked him. His answer was prompt. "The government is a liar." And how, I pressed, could he as a government employee, talk so frankly? "I work for the local government," he said, not the national government." One reason Ogai does not hesitate to express such views is that his top boss, Mayor Katsunobu Sakurai, gained fame after the tsunami for pleading with the government to assist with food and medicine.
  • By now the city is on its way to partial recovery. Shops have slowly come to life, schools reopened in October and rail services resumed this month going north. Encouraging though such signs may appear, they suggest only partial recovery. Business is slow. Only a few people drift in and out of food stores. A number of restaurants remain closed or on limited hours. As for the railroad, the trains are not expected for many years to go south to Tokyo, once a three-hour run through a densely populated region. "The railroad fears radioactive substances passing by the Fukushima plant," said one person to whom I spoke. "They can't enter the area."
  • Going north, the trains can only go as far as Soma, about 30 miles up the coast. Beyond that, on the way to the important port city of Sendai, the tsunami tore up the tracks
  • Mayor Sakurai is still asking volunteers to help while accusing central government officials and contractors of moving too slowly. People say TEPCO, the Tokyo Electric Power Company, is slow to provide compensation.
  • The lobby of the City Hall now is crowded with people looking for relief payments while Ogai fends off complaints about taxes the city is still levying on residents.
  • Ogai may be more concerned about the expense of monthly flights from Sendai to Osaka to see his family. "I request compensation from TEPCO. I often call the call center of TEPCO." The operator says, 'I am not sure'," said Ogai. "That is always the answer" - about as vague as responses to when TEPCO will finish cleaning up the nuke plant or what will be the impact of radiation on people 10, 20 or 30 years from now.

N.R.C. Chief Plans Quick Response to Post-Fukushima Study [18Jul11] - 0 views

  • The chairman of the Nuclear Regulatory Commission said Monday that it should decide within 90 days on how to address recommendations to be issued this week by a task force that examined the lessons of the Fukushima Daiichi nuclear accident in Japan. Almost simultaneously, House Republicans and the industry’s trade association warned him not to rush.
  • The chairman, Gregory B. Jaczko, speaking at the National Press Club, cast the March 11 earthquake and tsunami at Fukushima Daiichi, which produced three meltdowns, as a serious challenge for the American nuclear industry. “The history of nuclear power has also been punctuated by several significant events that challenged old truths and upended our understanding of nuclear safety,’’ he said.
  • The task force’s recommendations are to be issued on Tuesday. Mr. Jaczko did not say that the five-member commission should complete its work in 90 days, only that it should give strong direction on each recommendation by then. The work should be finished within five years, he said.
  • ...3 more annotations...
  • That may not sound like an urgent timetable to some people. But to put it into perspective, the commission is still struggling with issues raised by the Browns Ferry fire of 1975.
  • Mr. Jaczko cautioned that the nuclear safety effort should follow a principle used in medicine: first, do no harm. But the commission should exercise leadership promptly, he said. And the commission is trying to stick to its current schedule of issuing its first new construction license by the end of the year. But the industry, group, the Nuclear Energy Institute, took note of something else in the 90-day report: an observaiton that information from Japan was “unavailable, unreliable and ambiguous.”
  • changes in the hardened vents, which are supposed to route hydrogen out of the buildings before it can cause explosions, were premature because no one is sure what went wrong with the ones at Fukushima, Mr. Peterson said. Figuring that out could take years, he said.Meanwhile, leaders of the Republican majority on the House Energy and Commerce Committee released a letter they had sent to Mr. Jaczko warning him that “it is essential that the commission have the benefit of the full and deliberate process of review.’’

Vermont finds contaminated fish as nuclear debate rages [02Aug11] - 0 views

  • Vermont Yankee could close by March 2012 * Entergy fighting for reactor survival NEW YORK, Aug 2 (Reuters) - Vermont health regulators said on Tuesday they found a fish containing radioactive material in the Connecticut River near Entergy's (ETR.N) Vermont Yankee nuclear power plant which could be another setback for Entergy to keep it running. The state said it needs to do more testing to determine the source of the Strontium-90, which can cause bone cancer and leukemia.
  • Vermont Governor Peter Shumlin wants the 620 megawatts reactor shut in March 2012 when its original operating license was to expire. "Today's troubling news from the Vermont Department of Health is another example of Entergy Louisiana putting their shareholders' profits above the welfare of Vermonters," Shumlin said in a statement. "I am asking my Health Department to keep a close eye on test results moving forward to determine the extent of any contamination that has reached the environment."
  • New Orleans-based Entergy, the second biggest nuclear power operator in the United States, however wants to keep the reactor running for another 20 years under a new license. Entergy filed a complaint in federal court to block the state from shutting the reactor next year. Officials at Entergy were not immediately available for comment. "One finding of (Strontium-90) just above the lower limit of detection in one fish sample is notable because it is the first time Strontium-90 has been detected in the edible portion of any of our fish samples," the Vermont Department of Health said on its website. The Health Department said it did not know how the Strontium-90, which is both naturally occurring in the environment and a byproduct of nuclear power production and nuclear weapons testing, got into the fish.
  • ...2 more annotations...
  • "We cannot associate low levels of Strontium-90 in fish in the Connecticut River with Vermont Yankee-related radioactive materials without other supporting evidence," the report said. MORE ANALYSIS NEEDED The Health Department asked for additional analysis on the fish obtained on June 9, 2010 that contained the strontium-90 and also on other fish samples. These analyses will take weeks to complete, the Health Department said, noting it is working to obtain additional fish for testing much farther upstream in the Connecticut River. The Connecticut River divides Vermont and New Hampshire before running through Massachusetts and Connecticut. Vermont Yankee is located in Vernon, Vermont, near the border between Vermont, New Hampshire and Massachusetts about 110 miles northwest of Boston.
  • Strontium-90 and other human made radioactive materials come from the fairly constant release of very low quantities from medical and industrial users of radioactive materials, and from infrequent releases such as above-ground nuclear weapons testing in the 1950s, and the nuclear reactor accidents at Chernobyl in 1986 and Fukushima in 2011. Radioactive materials are nothing new for Vermont Yankee. In January 2010, Entergy said it discovered a radioactive tritium leak at the plant. The company stopped that leak in March 2010 but not before the state Senate, which was then led by now Governor Shumlin, voted to block the state from allowing the plant to run beyond March 2012.

Fukushima N-response centre lost functions [27Sep11] - 1 views

  • A power loss shut down an off-site emergency response centre near the Fukushima No 1 nuclear power plant for half a day after the Great East Japan Earthquake on March 11, delaying the initial response to the nuclear disaster at the power plant, according to sources. According to the Nuclear and Industrial Safety Agency, the centre lost its external power supply immediately after the earthquake, and an emergency diesel generator stopped operating soon after. Due to the power loss, agency officials stationed at the centre were unable to use important equipment such as monitors that show conditions inside the plant. The agency, which believes the earthquake caused the generator to break down, had not taken any anti-seismic reinforcement measures to protect the generator, the agency said.
  • The government panel tasked with investigating the nuclear crisis has begun studying the case, according to the sources. The off-site centre is located in Okumamachi, Fukushima Prefecture, about five kilometres from the nuclear power plant.

"Chim↑Pom" Japanese Art Collective Reflects the Disaster [19Oct11] - 0 views

  • The Fukushima nuclear power plant crisis highlighted not only Japan's dependency on nuclear energy, but also how strongly the public felt about it. Sept. 19 saw the nation's largest-ever antinuclear-energy demonstration in Tokyo's Meiji Park, and other protestors — including musicians, celebrities and artists — have been voicing their opinion through marches, activities and announcements.
  • Artist collective Chim↑Pom have already received a fair amount of press about their activities. They added, guerrilla-style, an image of a burning Fukushima power plant to Taro Okamoto's "Myth of Tomorrow" mural at Shibuya Station in central Tokyo, and then made a sand sculpture of a child wearing a gas mask in a Fukushima Prefecture playground that had been deemed unsafe for children. Now they're making a more intimate statement with "K-I-S-S-I-N-G" at the Container in the Nakameguro district of Tokyo. The exhibition — which manages to squeeze a video installation, a large photograph and a set of drawings into a freight-container space — is, say Chim↑Pom, "an allegory that uses lightbulbs to express the anxiety or loneliness people are still suffering since the earthquake (of March 11)." The door welcomes visitors with a red kiss mark from the lips of Ellie, the only female member of the collective, who has also written "XOXO Chim↑Pom" there in red lipstick. Immediately, there's a sense of intimacy, emphasized further by the tiny exhibition space.
  • "Shaken by anxiety and loneliness, people came to rediscover their close relationships," says Chim↑Pom on discussing the effect of the Great East Japan Earthquake. "There's been an increase in marriage and there may be fewer divorces from now on. Lovers are happy: They are reminded of the fantastic time they can share caring for each other. 'K-I-S-S-I-N-G' conveys those feelings that we can't put into words." The video, which is projected behind a display of broken lightbulbs, shows a pair of lightbulbs circling each other, "courting" and "cuddling." Chim↑Pom say the incandescent bulbs are an obvious reference to electricity issues — because such bulbs are now being replaced by more electricity-efficient LED versions, they serve as a stronger visual link to the nuclear energy that Japan has relied on for decades. The bulbs break and burst into flames when they kiss onscreen.

  • Though the collective claim they can't explain the artwork's true message, their installation does suggest a reliance on what many now see as an unstable and dangerous source of energy, while also referencing our heightened desire for meaningful companionship since the March 11 disaster

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.

Post-Fukushima, Nuclear Power Changes Latitudes - [28Nov11] - 0 views

  • As the full cost of the Fukushima nuclear accident continues to climb—Japanese officials now peg it at $64 billion or more—nuclear power’s future is literally headed south. Developed countries are slowing or shuttering their nuclear-power programs, while states to their south, in the world’s hotspots (think the Middle East and Far East), are pushing to build reactors of their own. Normally, this would lead to even more of a focus on nuclear safety and nonproliferation. Yet, given how nuclear-reactor sales have imploded in the world’s advanced economies, both these points have been trumped by nuclear supplier states’ desires to corner what reactor markets remain.
  • This spring, Germany permanently shut down eight of its reactors and pledged to shutter the rest by 2022. Shortly thereafter, the Italians voted overwhelmingly to keep their country nonnuclear. Switzerland and Spain followed suit, banning the construction of any new reactors. Then Japan’s prime minister killed his country’s plans to expand its reactor fleet, pledging to reduce Japan’s reliance on nuclear power dramatically. Taiwan’s president did the same. Now Mexico is sidelining construction of 10 reactors in favor of developing natural-gas-fired plants, and Belgium is toying with phasing its nuclear plants out, perhaps as early as 2015.
  • China—nuclear power’s largest prospective market—suspended approvals of new reactor construction while conducting a lengthy nuclear-safety review. Chinese nuclear-capacity projections for the year 2020 subsequently tumbled by as much as 30 percent. A key bottleneck is the lack of trained nuclear technicians: to support China’s stated nuclear-capacity objectives, Beijing needs to graduate 6,000 nuclear experts a year. Instead, its schools are barely generating 600.
  • ...7 more annotations...
  • India, another potential nuclear boom market, is discovering a different set of headaches: effective local opposition, growing national wariness about foreign nuclear reactors, and a nuclear liability controversy that threatens to prevent new reactor imports. India was supposed to bring the first of two Russian-designed reactors online this year in tsunami-prone Tamil Nadu state. Following Fukushima, though, local residents staged a series of starvation strikes, and the plant’s opening has now been delayed. More negative antinuclear reactions in the nearby state of West Bengal forced the local government to pull the plug on a major Russian project in Haripur. It’s now blocking an even larger French reactor-construction effort at Jaitapur.
  • These nuclear setbacks come as Prime Minister Manmohan Singh is straining to reconcile India’s national nuclear-accident-liability legislation with U.S. demands that foreign reactor vendors be absolved of any responsibility for harm that might come to property or people outside of a reactor site after an accident
  • n the United States, new-reactor construction has also suffered—not because of public opposition but because of economics
  • persuade his Parliament to cap foreign vendors’ liability to no more than $300 million (even though Japan has pegged Fukushima damages at no less than $64 billion).
  • The bottom line is that in 2007, U.S. utilities applied to the Nuclear Regulatory Commission to build 28 nuclear-power plants before 2020; now, if more than three come online before the end of the decade, it will be a major accomplishment.
  • France—per capita, the world’s most nuclear-powered state. Frequently heralded as a nuclear commercial model for the world, today it’s locked in a national debate over a partial nuclear phaseout.
  • his Socialist opponent, François Hollande, now well ahead in the polls, has proposed cutting nuclear power’s contribution to the electrical grid by more than a third by 2025. Hollande is following a clear shift in French public opinion, from two thirds who backed nuclear power before Fukushima to 62 percent who are now favoring a progressive phaseout. In addition, the French courts just awarded Greenpeace €1.5 million against the French nuclear giant EDF for illegally spying on the group. Public support of this judgment and the French Socialist Party’s wooing of the French Greens makes the likelihood of Hollande backing off his pledge minuscule.

Drinking the Radioactive Kool-Aid: Countries Switching From Coal to Nuclear [02Dec11] - 0 views

  • South Africa, the host of U.N. global climate talks, is faced with a conundrum -- it wants to wean itself off of coal-powered plants seen as primate culprits of greenhouse gas emissions and find a cleaner energy source.It is turning to nuclear power, despite the catastrophic environmental degradation the world witnessed after Japan's Fukushima plant disaster this year.
  • The global climate talks that opened earlier this week in Durban are seeing a widening division on nuclear power, with many advanced economies moving away from it after Fukushima and emerging states heavily reliant on fossil fuels embracing it as a cleaner way to power their development. "If you want to be part of the climate change race and mitigation you basically have renewables and nuclear. Renewables are intermittent and you need a firm and reliable baseload technology. Renewables are not in a position to provide this yet," said H. Holger Rogner, section head of the International Atomic Energy Agency's planning and economic studies section. South Africa, among the world's top 20 emitters per capita of carbon dioxide, and many other emerging countries, see nuclear power as a way to ensure energy security for the coming years and as a bridge to a time when they are rich enough to afford adding more renewables to their power mix.
  • The Fukushima disaster changed the economics of the nuclear industry by drying up markets in developed countries such as Japan and increasing competition among the few global conglomerates who can build nuclear power plants.

Will California close all nuclear plants in 2012? Secretary of State approves ballot in... - 0 views

  • Ballot Initiative to Close Nuclear Plants Gets Go-Ahead for Signature Collection, San Clemente Times by Stacie N. Galang, Nov 22, 2011: California’s Secretary of State approved a ballot initiative November 18 that seeks the closure of San Onofre Nuclear Generating Station and the Diablo Canyon plant. The initiative was filed by Ben Davis Jr. [who] drafted this and an earlier petition that led to the closure of the Rancho Seco power plant in June 1989.
  • As drafted, the latest initiative parallels existing state law prohibiting the creation of new nuclear plants until the federal government finds a solution to dispose of radioactive nuclear waste and reprocess spent fuel rods. If enacted, the initiative would essentially shut down the state’s two remaining nuclear plants by stopping them from creating additional waste until a federal solution arrives. [...] Davis has until April 16, 2012 to collect the 504,760 needed signatures to allow the initiative to go the voters in the fall presidential election. He expected to start the signature drive after the Thanksgiving weekend.

Tepco: 68 tons of nuclear fuel melted at Fukushima Reactor No. 1 [02Dec11] - 0 views

  • All N-fuel may have fallen to outer vessel / TEPCO: Up to 68 tons likely melted in No. 1 reactor, eroding concrete of containment unit, The Yomiuri Shimbun, Dec. 2, 2011: [...] The nuclear fuel at the No. 1 reactor melted as its temperature reached nearly 3,000 C at one time, TEPCO estimated. In the No. 1 reactor, TEPCO believes, almost all of the about 68 tons of fuel melted. [...]
  • TEPCO currently maintains a steady supply of water to the three reactors, enabling the No. 1 reactor to always have about 40 centimeters of cool water at the bottom of the containment vessel, enough to cover the melted fuel, according to the utility. [...]
