U.S. used Hiroshima to bolster support for nuclear power [26Jul11] - 0 views

  • The private notes of the head of a U.S. cultural center in Hiroshima revealed that Washington targeted the city's residents with pro-nuclear propaganda in the mid-1950s after deciding a swing in their opinions was vital to promoting the use of civil nuclear power in Japan and across the world. The organizers of a U.S.-backed exhibition that toured 11 major Japanese cities from November 1955 to September 1957 initially considered opening the first exhibition in Hiroshima.
  • According to the private papers of Abol Fazl Fotouhi, former president of the American Cultural Center in Hiroshima, the idea of choosing the city was proposed at a meeting of officials of the U.S. Information Service in December 1954.
  • The proposal was dropped because officials were worried that it would link nuclear energy too closely with nuclear bombs. Tokyo was chosen to open the tour and three other cities were visited before the exhibition opened at the Hiroshima Peace Memorial Museum, which commemorates the 1945 bombing, on May 27, 1956.

  • However, the city remained at the heart of Washington's drive to directly intervene in the Japanese debate on nuclear energy at a critical time in the relationship between the two nations and the Cold War. Anti-nuclear sentiment in Japan had been aggravated by the contamination of the crew of the Japanese fishing boat Daigo Fukuryu Maru by fallout from the Bikini Atoll nuclear test early in 1954.
  • The previous year, successful hydrogen bomb tests by the Soviet Union had prompted the United States to shift its policy from keeping close control of nuclear technology to bolstering relations with friendly countries by sharing its expertise. The campaign in Japan was just one part of an international effort to promote nuclear energy's peaceful use. Yuka Tsuchiya, a professor of Ehime University and an expert on U.S. public diplomacy, said the U.S. government decided acceptance by Hiroshima residents of peaceful nuclear use would have a major impact on Japanese and world public opinion.
  • Fotouhi, who was in charge of organizing the Hiroshima event, launched an intensive campaign to win over locals.
  • His daughter, who came to Japan with him in 1952 and went to a local elementary school in Hiroshima, said her father invited nearly 100 people to his house to explain its aims. He gathered the support of the city government, the prefectural government, Hiroshima University and local newspapers and managed to stop protests by convincing activists of the event's importance to the peaceful use of nuclear power
  • The exhibition attracted long lines. A remotely operated machine for handling hazardous materials, called Magic Hand, was among the most popular attractions. One 74-year-old woman who had been a victim of the 1945 bombing asked one of the exhibition staff if the machine posed any harm to human health. The staff member said nuclear power could be of great value to human life if used for the public good, according to the woman.
  • On June 18, 1956, the day after the Hiroshima event closed, the U.S. Embassy in Japan reported to Washington that 120,000 visitors had attended over its three-week run.
  • A senior official of the U.S. Atomic Energy Commission said in another report that the event had swayed the Japanese public's views of nuclear energy. No other country was as supportive of U.S. President Dwight Eisenhower's promotion of the peaceful use of nuclear power as Japan, the official said.
  • In total, 2.7 million people visited the exhibitions in the 11 major cities. A scaled-down version of the exhibition later toured rural areas of Japan.
  • Japan's first nuclear reactor, imported from the United States, began operating in Tokai, Ibaraki Prefecture, in August 1957, the month before the end of the exhibition tour.
  •  
    How the U.S., after nuking Japan, launched its nuclear power campaign there to win over public opinion. It worked.

Speaking tour of Japan challenges financing for new U.S. reactors [20Aug10] - 0 views

  • Beyond Nuclear's Kevin Kamps toured Japan from August 2nd to 12th, visiting Tokyo, Fukushima, Fukui, Kansai and Kyushu. A highlight included meeting with officials from the Japan Bank for International Cooperation and the Nippon Export and Investment Insurance agency, where a letter signed by 75 U.S. national and grassroots groups was delivered, urging no Japanese financing for risky new reactors in the U.S. A backgrounder spelled out these risks in detail. Most proposed new U.S. atomic reactors have designs owned by Japanese companies -- either Toshiba (Westinghouse), Hitachi (General Electric), or Mitsubishi. At South Texas Project, Toshiba and Tokyo Electric Power Company are even partners in the venture. In addition, Japan Steel Works would be the primary supplier of large nuclear components, such as reactor pressure vessels and steam generators. The Japanese news media were alerted to the letter and meeting, and the Japanese Prime Minister, Minister of Finance, and Minister of Economy, Trade, and Industry received copies of the letter.

Bloomberg: Crack in reactor containment structure at quake-hit Virginia nuke plant - Pr... - 0 views

  • Dominion Says Crack Found at North Anna Containment Building, Bloomberg, September 2, 2011:
  • Dominion Resources Inc. found a small crack on a wall with “no safety significance” in a room of a containment building at the North Anna nuclear plant [...] Dominion discovered a “cosmetic” crack in a horizontal construction joint on a wall that is in the containment building, [Dan Stoddard, the Dominion's senior vice president for nuclear operations] said. [...] Dominion invited reporters to tour the plant’s control room, transformer and generator areas. Company officials didn’t take the group into the reactor containment structure or the building that houses a cooling pool for spent fuel because that would have been “more complex and more time-consuming,” Stoddard said.

Safecast: Global sensor network collects and shares radiation data via CC0 - Creative C... - 0 views

  • One week after the nuclear disaster at the Fukushima Diachi plant in March, the Safecast project was born to respond to the information needs of Japanese citizens regarding radiation levels in their environment. Safecast, then known as RDTN.org, started a campaign on Kickstarter “to provide an aggregate feed of nuclear radiation data from governmental, non-governmental and citizen-scientist sources.” All radiation data collected via the project would be dedicated to the public domain using CC0, “available to everyone, including scientists and nuclear experts who can provide context for lay people.” Since then, more than 1.25 million data points have been collected and shared; Safecast has been featured on PBS Newshour; and the project aims to expand its scope to mapping the rest of the world.
  • “Safecast supports the idea that more data – freely available data – is better. Our goal is not to single out any individual source of data as untrustworthy, but rather to contribute to the existing measurement data and make it more robust. Multiple sources of data are always better and more accurate when aggregated. While Japan and radiation is the primary focus of the moment, this work has made us aware of a need for more environmental data on a global level and the longterm work that Safecast engages in will address these needs. Safecast is based in the US but is currently focused on outreach efforts in Japan. Our team includes contributors from around the world.”

U.S. nuke regulators weaken safety rules [20Jun11] - 0 views

  • Federal regulators have been working closely with the nuclear power industry to keep the nation's aging reactors operating within safety standards by repeatedly weakening standards or simply failing to enforce them, an investigation by The Associated Press has found.Officials at the U.S. Nuclear Regulatory Commission regularly have decided original regulations were too strict, arguing that safety margins could be eased without peril, according to records and interviews.The result? Rising fears that these accommodations are undermining safety -- and inching the reactors closer to an accident that could harm the public and jeopardize nuclear power's future.
  • Examples abound. When valves leaked, more leakage was allowed -- up to 20 times the original limit. When cracking caused radioactive leaks in steam generator tubing, an easier test was devised so plants could meet standards.Failed cables. Busted seals. Broken nozzles, clogged screens, cracked concrete, dented containers, corroded metals and rusty underground pipes and thousands of other problems linked to aging were uncovered in AP's yearlong investigation. And many of them could escalate dangers during an accident.
  • Despite the problems, not a single official body in government or industry has studied the overall frequency and potential impact on safety of such breakdowns in recent years, even as the NRC has extended dozens of reactor licenses.Industry and government officials defend their actions and insist no chances are being taken. But the AP investigation found that with billions of dollars and 19 percent of America's electricity supply at stake, a cozy relationship prevails between industry and the NRC.Records show a recurring pattern: Reactor parts or systems fall out of compliance. Studies are conducted by industry and government, and all agree existing standards are "unnecessarily conservative."
  • ...14 more annotations...
  • Regulations are loosened, and reactors are back in compliance."That's what they say for everything ...," said Demetrios Basdekas, a retired NRC engineer. "Every time you turn around, they say, 'We have all this built-in conservatism.' "The crisis at the decades-old Fukushima Dai-ichi nuclear facility in Japan has focused attention on nuclear safety and prompted the NRC to look at U.S. reactors. A report is due in July.But the factor of aging goes far beyond issues posed by Fukushima.
  • Commercial nuclear reactors in the United States were designed and licensed for 40 years. When the first were built in the 1960s and 1970s, it was expected that they would be replaced with improved models long before their licenses expired.That never happened. The 1979 accident at Three Mile Island, massive cost overruns, crushing debt and high interest rates halted new construction in the 1980s.Instead, 66 of the 104 operating units have been relicensed for 20 more years. Renewal applications are under review for 16 other reactors.As of today, 82 reactors are more than 25 years old.The AP found proof that aging reactors have been allowed to run less safely to prolong operations.
  • Last year, the NRC weakened the safety margin for acceptable radiation damage to reactor vessels -- for a second time. The standard is based on a reactor vessel's "reference temperature," which predicts when it will become dangerously brittle and vulnerable to failure. Through the years, many plants have violated or come close to violating the standard.As a result, the minimum standard was relaxed first by raising the reference temperature 50 percent, and then 78 percent above the original -- even though a broken vessel could spill radioactive contents."We've seen the pattern," said nuclear safety scientist Dana Powers, who works for Sandia National Laboratories and also sits on an NRC advisory committee. "They're ... trying to get more and more out of these plants."
  • Sharpening the pencilThe AP study collected and analyzed government and industry documents -- some never-before released -- of both reactor types: pressurized water units that keep radioactivity confined to the reactor building and the less common boiling water types like those at Fukushima, which send radioactive water away from the reactor to drive electricity-generating turbines.The Energy Northwest Columbia Generating Station north of Richland is a boiling water design that's a newer generation than the Fukushima plants.Tens of thousands of pages of studies, test results, inspection reports and policy statements filed during four decades were reviewed. Interviews were conducted with scores of managers, regulators, engineers, scientists, whistleblowers, activists and residents living near the reactors at 65 sites, mostly in the East and Midwest.
  • AP reporters toured some of the oldest reactors -- Oyster Creek, N.J., near the Atlantic coast 50 miles east of Philadelphia and two at Indian Point, 25 miles north of New York City on the Hudson River.Called "Oyster Creak" by some critics, this boiling water reactor began running in 1969 and is the country's oldest operating commercial nuclear power plant. Its license was extended in 2009 until 2029, though utility officials announced in December they will shut the reactor 10 years earlier rather than build state-ordered cooling towers. Applications to extend the lives of pressurized water units 2 and 3 at Indian Point, each more than 36 years old, are under NRC review.Unprompted, several nuclear engineers and former regulators used nearly identical terminology to describe how industry and government research has frequently justified loosening safety standards. They call it "sharpening the pencil" or "pencil engineering" -- fudging calculations and assumptions to keep aging plants in compliance.
  • Cracked tubing: The industry has long known of cracking in steel alloy tubing used in the steam generators of pressurized water reactors. Ruptures have been common in these tubes containing radioactive coolant; in 1993 alone, there were seven. As many as 18 reactors still run on old generators.Problems can arise even in a newer metal alloy, according to a report of a 2008 industry-government workshop.
  • Neil Wilmshurst, director of plant technology for the industry's Electric Power Research Institute, acknowledged the industry and NRC often collaborate on research that supports rule changes. But he maintained there's "no kind of misplaced alliance ... to get the right answer."Yet agency staff, plant operators and consultants paint a different picture:* The AP reviewed 226 preliminary notifications -- alerts on emerging safety problems -- NRC has issued since 2005. Wear and tear in the form of clogged lines, cracked parts, leaky seals, rust and other deterioration contributed to at least 26 of the alerts. Other notifications lack detail, but aging was a probable factor in 113 more, or 62 percent in all. For example, the 39-year-old Palisades reactor in Michigan shut Jan. 22 when an electrical cable failed, a fuse blew and a valve stuck shut, expelling steam with low levels of radioactive tritium into the outside air. And a 1-inch crack in a valve weld aborted a restart in February at the LaSalle site west of Chicago.
  • * A 2008 NRC report blamed 70 percent of potentially serious safety problems on "degraded conditions" such as cracked nozzles, loose paint, electrical problems or offline cooling components.* Confronted with worn parts, the industry has repeatedly requested -- and regulators often have allowed -- inspections and repairs to be delayed for months until scheduled refueling outages. Again and again, problems worsened before being fixed. Postponed inspections inside a steam generator at Indian Point allowed tubing to burst, leading to a radioactive release in 2000. Two years later, cracking grew so bad in nozzles on the reactor vessel at the Davis-Besse plant near Toledo, Ohio, that it came within two months of a possible breach, an NRC report said, which could release radiation. Yet inspections failed to catch the same problem on the replacement vessel head until more nozzles were found to be cracked last year.
  • Time crumbles thingsNuclear plants are fundamentally no more immune to aging than our cars or homes: Metals grow weak and rusty, concrete crumbles, paint peels, crud accumulates. Big components like 17-story-tall concrete containment buildings or 800-ton reactor vessels are all but impossible to replace. Smaller parts and systems can be swapped but still pose risks as a result of weak maintenance and lax regulation or hard-to-predict failures.Even mundane deterioration can carry harsh consequences.For example, peeling paint and debris can be swept toward pumps that circulate cooling water in a reactor accident. A properly functioning containment building is needed to create air pressure that helps clear those pumps. But a containment building could fail in a severe accident. Yet the NRC has allowed safety calculations that assume the buildings will hold.
  • In a 2009 letter, Mario V. Bonaca, then-chairman of the NRC's Advisory Committee on Reactor Safeguards, warned that this approach represents "a decrease in the safety margin" and makes a fuel-melting accident more likely.Many photos in NRC archives -- some released in response to AP requests under the federal Freedom of Information Act -- show rust accumulated in a thick crust or paint peeling in long sheets on untended equipment.Four areas stand out:
  • Brittle vessels: For years, operators have rearranged fuel rods to limit gradual radiation damage to the steel vessels protecting the core and keep them strong enough to meet safety standards.But even with last year's weakening of the safety margins, engineers and metal scientists say some plants may be forced to close over these concerns before their licenses run out -- unless, of course, new regulatory compromises are made.
  • Leaky valves: Operators have repeatedly violated leakage standards for valves designed to bottle up radioactive steam in an earthquake or other accident at boiling water reactors.Many plants have found they could not adhere to the general standard allowing main steam isolation valves to leak at a rate of no more than 11.5 cubic feet per hour. In 1999, the NRC decided to allow individual plants to seek amendments of up to 200 cubic feet per hour for all four steam valves combined.But plants have violated even those higher limits. For example, in 2007, Hatch Unit 2, in Baxley, Ga., reported combined leakage of 574 cubic feet per hour.
  • "Many utilities are doing that sort of thing," said engineer Richard T. Lahey Jr., who used to design nuclear safety systems for General Electric Co., which makes boiling water reactors. "I think we need nuclear power, but we can't compromise on safety. I think the vulnerability is on these older plants."Added Paul Blanch, an engineer who left the industry over safety issues, but later returned to work on solving them: "It's a philosophical position that (federal regulators) take that's driven by the industry and by the economics: What do we need to do to let those plants continue to operate?"Publicly, industry and government say that aging is well under control. "I see an effort on the part of this agency to always make sure that we're doing the right things for safety. I'm not sure that I see a pattern of staff simply doing things because there's an interest to reduce requirements -- that's certainly not the case," NRC chairman Gregory Jaczko said in an interview.
  • Corroded piping: Nuclear operators have failed to stop an epidemic of leaks in pipes and other underground equipment in damp settings. Nuclear sites have suffered more than 400 accidental radioactive leaks, the activist Union of Concerned Scientists reported in September.Plant operators have been drilling monitoring wells and patching buried piping and other equipment for several years to control an escalating outbreak.But there have been failures. Between 2000 and 2009, the annual number of leaks from underground piping shot up fivefold, according to an internal industry document.

Reporters at damaged reactor plant told to stay in the bus [14Nov11] - 0 views

  • The most striking feature at this crippled plant was not the blasted-out reactor buildings, or makeshift tsunami walls, but the chaotic mess. The ground around the four hulking reactor buildings was littered with mangled trucks, twisted metal beams and broken building frames, left mostly as they were after Japan's March 11 earthquake and tsunami.
  • The media tour of the site, the first since disaster struck on March 11, appeared to be Tokyo Electric Power Co's way of declaring its confidence that it is close to stabilising the plant. That message was driven home by the minister supervising the government's response to the nuclear accident, Goshi Hosono, who visited the plant at the same time as the journalists
  • Speaking to hundreds of workers, Mr Hosono praised their hard work in difficult and dangerous conditions. But the hopeful talk skims over more troubling truths. Two weeks ago, TEPCO announced it found signs one of the reactor cores may have had a burst of fission, a frightening sign the company might not be as close to a stable shutdown as it said. While no one died in the nuclear accident, the environmental and human costs were clear during the 20 kilometre drive to the plant through the evacuation zone.

  • The dosimeters of the journalists on the bus buzzed constantly, recording levels that ticked up with each passing kilometre: 0.7 microsieverts in Naraha, at the edge of the evacuation zone; 1.5 at Tomioka, where the welcome centre for Fukushima Daiichi told Japanese visitors that nuclear power was safe. Saturday's level was 13 times the recommended maximum annual dosage for civilians. At the plant, journalists, outfitted in full contamination suits, were kept aboard the bus in recognition of the much higher radiation levels there. One worker, Hiroyuki Shida, 57, said ''radiation levels aren't so high outside the buildings. But they are still high within the reactor buildings''.

Press gain access to Fukushima plant / Media get firsthand look at devastation caused b... - 0 views

  • Joining the first press tour to the power plant, eight months after the Great East Japan Earthquake, I headed to the site aboard a bus from J-Village about 20 kilometers south. Originally a sports facility, J-Village is currently used as the base for workers at the crippled plant. Wearing protective gear along with cotton and rubber gloves on each hand, I began to sweat even before being told to put on a full-face mask about three kilometers from the plant. We had to wear the masks to prevent internal radiation exposure, but I had difficulty breathing because the mask stuck to my face every time I inhaled. I imagined it would be quite hard to work in this clothing. Guards in the same outfits stood at the main gate of the plant, keeping an eye on comings and goings.
  • Aboard the bus was a worker tasked with checking radiation, who constantly read out radiation levels. Tension on the bus spiked when he said, "It's 20 microsieverts per hour." I realized how devastating the accident was when we arrived on a hill about 34 meters above sea level to take in a wider view of the site. From the hill, we could see the 45-meter-high No. 4 reactor building in the foreground, which had been severely damaged with only its steel framework remaining. I also spotted a large green crane used to pull nuclear fuel from the pressure vessel--it should not have been visible as it is supposed to be inside the building. Behind the No. 4 reactor building was the No. 3 building, which showed much more severe damage with bent steel beams clearly visible.
  • The reactor buildings, which are the last line of defense to prevent radioactive materials from leaking, have one-meter-thick concrete walls. I was overwhelmed to see the devastating power of the explosions that destroyed such solid walls.
  • ...2 more annotations...
  • It's 40 microsieverts [per hour]," we were told when the bus arrived near the coast, about 10 meters above sea level
  • There were several large trailers stuck in the ground near the No. 3 and No. 4 turbine buildings, and a nearby cafeteria building's first floor was destroyed. The lower part of the turbine buildings, on the other hand, showed almost no damage as they were sturdy enough to withstand the power of the tsunami, but could not prevent the water from leaking in through small openings. Had the emergency generators not been in the basements of the turbine buildings, they would not have been submerged and could have prevented the nuclear crisis from developing.

Don't Be Fooled By the Spin - Radiation is Bad [06Apr11] - 0 views

  • Ziggy Switkowski, former chair of ANSTO (Australian Nuclear Science and Technology Organisation) and a proponent of nuclear power for Australia, claimed "the best place to be whenever there's an earthquake is at the perimeter of a nuclear plant because they are designed so well", and then quickly added: "On the other hand, you know, if the engineers do lose control of the core, then the answer becomes different."
  • Strident nuclear advocate Professor Barry Brook gave assurances in his running commentary that seemed ironically prescient of what was about to happen, stating ''I don't see the ramifications of this as damaging at all to nuclear power's prospects'' and that ''it will provide a great conversation starter for talking intelligently to people about nuclear safety''.
  • Other arguments trotted out by pro-nuclearists about how safe nuclear power is demonstrated their chutzpah more than their good judgment. My favourite: the justification for nuclear power is that it kills fewer people than the coal industry. Ignoring the false choice this proposition entails, what does it say about the safety culture of the nuclear industry when one of its selling points is that it kills fewer people than the competition?
  • ...8 more annotations...
  • But more insidious and objectionable is the creeping misinformation that the nuclear industry has fed into the public sphere over the years. There seems to be a never-ending cabal of paid industry scientific ''consultants'' who are more than willing to state the fringe view that low doses of ionising radiation do not cause cancer and, indeed, that low doses are actually good for you and lessen the incidence of cancer. Canadian Dr Doug Boreham has been on numerous sponsored tours of Australia by Toro Energy, a junior uranium explorer, expounding the view that "low-dose radiation is like getting a suntan". Toro must have liked what it heard because it made him a safety consultant for the company in 2009.
  • Ionising radiation is a known carcinogen. This is based on almost 100 years of cumulative research including 60 years of follow-up of the Japanese atom bomb survivors. The International Agency for Research in Cancer (IARC, linked to the World Health Organisation) classifies it as a Class 1 carcinogen, the highest classification indicative of certainty of its carcinogenic effects.
  • In 2006, the US National Academy of Sciences released its Biological Effects of Ionising Radiation (VII) report, which focused on the health effects of radiation doses at below 100 millisieverts. This was a consensus review that assessed the world's scientific literature on the subject at that time. It concluded: ". . . there is a linear dose-response relationship between exposure to ionising radiation and the development of solid cancers in humans. It is unlikely that there is a threshold below which cancers are not induced."
  • The most comprehensive study of nuclear workers by the IARC, involving 600,000 workers exposed to an average cumulative dose of 19mSv, showed a cancer risk consistent with that of the A-bomb survivors
  • April 26 marks the 25th anniversary of the Chernobyl disaster. The pro-nuclearists have gone into full-spin-ahead mode, misrepresenting the latest UNSCEAR (United Nations Scientific Committee on the Effects of Atomic Radiation) report on Chernobyl.
  • Two days ago on this page, George Monbiot (''How the anti-nuclear lobby misled us all with dodgy claims''), citing the report, wrongly plays down he death toll. He correctly states that the report found 6848 cases of thyroid cancer in children, although he fails to acknowledge it was due to the effects of radioactive iodine in the nuclear fallout. The number of cases will continue to increase, according to the US National Cancer Institute, for a further 10 to 20 years.
  • Thyroid cancer is easy to detect because it is normally a rare cancer. Most other cancers caused by radiation are not that easy to detect above the high background natural rates of cancer. It is the proverbial needle in a haystack scenario - but in this case the needles (radiation-induced cancer) look the same as the hay (other cancers). What the report therefore said was that statistical limitations and large uncertainties precluded being able to single out any radiation-induced cancers. It did not say there have been no cancers, as Monbiot and others claim, or that none will develop, only that it is not possible at this stage to detect them.
  • IARC states that ''by 2065, predictions based on these models indicate that about 16,000 cases of thyroid cancer and 25,000 cases of other cancers may be expected due to radiation from the accident and that about 16,000 deaths from these cancers may occur''. Whether we will be able to detect them when there will also be more than 1 million other cases of cancer over this period is debatable. But every one of these excess cancers is a tragedy for each victim and their family, and is no less so simply because cancer is a common disease. George Monbiot should read properly the BEIR VII report that Helen Caldicott gave him - all 423 pages

In Sweden, A Tempered Approach To Nuclear Waste [28Jul11] - 0 views

  • At least two dozen countries around the globe get energy from nuclear power, yet not one has been able to pull off a permanent disposal site. Finding communities willing to live with such dangerous stuff has been a big sticking point. But in Sweden, two communities have stepped up, and are willing to take the country's waste. Like many countries, Sweden has had its share of political meltdowns over nuclear power. Protests stirred an uproar in the early 1980s when the Swedish nuclear industry simply decided where to begin testing for a possible geologic disposal site.
  • But today, instead of deflecting protesters, the nuclear industry shuttles visitors by the busloads for guided tours of facilities. More than 1,100 feet below the surface, exotic machinery and copper tubes wide enough to fit two men fill an underground cavern carved from crystalline bedrock. In this working lab in eastern Sweden, a private nuclear waste company tests methods for permanently storing used fuel. It plans to encase the fuel rods in copper capsules, then bury them 1,500 feet down in bedrock where it is supposed to sit for the next 100,000 years.
  • how did nuclear waste in Sweden go from a toxic topic to a field trip? People in the area said the industry needed to start over with things like public participation, a transparent, predictable process and trust. The industry took these lessons to heart. "We know that we have to meet people and communicate what we want to do, why we want to do it and how we will find a place for it," says Inger Nordholm, a spokeswoman for the Swedish Nuclear Fuel and Waste Management Company, or SKB.

  • Lilliemark says she learned a lot about the risks of not dealing with the used fuel. And it changed her thinking. "I can't just close my eyes and imagine that the fuel is not here, because it is," she says.
  • "I couldn't see anything that was positive," she says. But then local government officials asked her to lead a community advisory group. She says they told her: "We think you could contribute to the work — we need to open all the questions and be clear and transparent, and we want you to participate if you want to." And she did.
  • Oskarshamn was one of two communities in eastern Sweden that stepped forward after nuclear waste officials asked for volunteers willing to let them start geologic testing. Charlotte Lilliemark, who lives about 12 miles north of the town, was just the kind of person a nuclear power executive would want to avoid. The former Stockholmer moved to the country to raise dressage horses and didn't want a waste dump anywhere near her
  • This spring, Swedish nuclear officials applied for a licensing application to build a geologic vault in the municipality of Osthammar, about a two-hour drive north of Stockholm. If they get it, the facility could open in 2025. "We believe that it will not create a stigma, but on the other hand create an interest in how to solve this very difficult issue that people in Japan and California and Germany must solve in one way or another," says Jacob Spangenberg, the mayor of Osthammar.
  • The community will see some financial benefits: Besides new jobs and infrastructure, Osthammar negotiated a deal with the company to receive approximately $80 million for long-term economic development if the repository is approved
  • Already the community gets money from a national waste fund to help it chart an independent course. It has retained technical consultants and hired five full-time employees. Spangenberg says Osthammar learned how to ask tough questions, press for conditions and also to keep cool.

NISA Says Stress Tests to RestartJapanese Reactors Will Take Months [26Jul11] - 0 views

  • Plant Status After a 6.2 magnitude earthquake struck offshore from Fukushima in the early hours of July 25, Tokyo Electric Power Co. reported there were no problems with any of the systems used to stabilize the reactors at Fukushima Daiichi and no injuries. TEPCO checked the systems for water and nitrogen injection into reactors 1, 2 and 3, the water treatment facility, and the used fuel pool cooling systems for reactors 2 and 3. The Japan Atomic Industry Forum said temperatures at the bottom of Fukushima Daiichi reactor 1 have remained below 100 degrees Celsius (212 Fahrenheit) for six consecutive days through July 24. TEPCO says it achieved the lowered temperature by raising the amount of water injected into the reactor. The company has begun implementing step 2 of its recovery plan for the reactors, which includes maintaining temperatures at the bottom of reactors 1, 2 and 3 below 100 degrees Celsius. The stable operation of the circulatory water injection system is crucial to achieving that goal. TEPCO said a faulty circuit breaker was the cause of a five-hour loss of electrical power to reactors 3 and 4 July 22. Power for contaminated water treatment and for the reactors’ used fuel pool cooling was eventually restored via an alternate source. TEPCO says there was no major increase in the temperature of the pools
  • The company is working to improve switching systems among external power supplies. Industry/Regulatory/Political Issues A July 28 public Nuclear Regulatory Commission meeting will focus on the agency’s near-term task force recommendations for safety enhancements at U.S. nuclear energy facilities after the Fukushima accident. International Atomic Energy Agency Director General Yukiya Amano today toured the Fukushima Daiichi site, where he met with TEPCO personnel and gave an interview on location describing his visit. Amano is to meet Japanese Prime Minister Naoto Kan and government ministers to discuss the outcomes of the June IAEA ministerial conference on nuclear safety. The Nuclear and Industrial Safety Agency said it will take months to complete the first of two-stage “stress tests” it has ordered all Japanese nuclear power reactor operators to conduct before shutdown reactors can restart. NISA said it does not anticipate any of the 22 reactors that were halted for regular safety checks to resume operations this summer. The tests involve computer simulations of the reactors’ responses to emergencies such as earthquakes, tsunamis and loss of off-site power.
  • As TEPCO moves into the second stage of its recovery plan at Fukushima, the joint office it operates with the Japanese government to conduct and review its activities will be restructured. A new radiation and health management team will be established, and two other teams will be incorporated into a “medium-to-long term countermeasures” team. Media Highlights The New York Times editorialized on July 24 on the U.S. response to the Fukushima Daiichi accident. The opinion piece discussed steps taken by the nuclear energy industry and recommendations made by the NRC’s Fukushima-focused task force.

4 Ways the Department of Energy Is Tapping Tech for a Greener Future [03Aug11] - 0 views

  • This week, the U.S. Department of Energy (DOE) re-launched its website, Energy.gov, to provide tools to help individuals and businesses better understand how to save energy and money. You can type your zip code into the site and get hyper-local information about your city, county and state, including information on tax credits, rebates and energy saving tips.
  • The site presents DOE data visually using the open source MapBox suite of tools, and localized data and maps can be shared or embedded on any website or blog. Other data sets the DOE is mapping include alternative fuel locations and per capita energy usage. Anyone can now compare how his state’s energy usage compares with others across the country. In addition to making the data more palatable for the public, the DOE is offering open data sets for others to use.
  • Our goal is simple — to improve the delivery of public services online. We’re using government data to go local in a way that’s never been possible before. We’re connecting the work of the Energy Department with what’s happening in your backyard,” says Cammie Croft, senior advisor and director of new media and citizen engagement at the DOE. “We’re making Energy.gov relevant and accessible to consumers and small businesses in their communities.”

  • How else is the Energy Department working to bring better information about energy, renewable energies and energy technology to the public? Here are a few examples.
  • 1. Your MPG
  • The “Your MPG” feature on the site lets you upload data about your own vehicle’s fuel usage to your “cyber” garage and get a better picture of how your vehicle is doing in terms of energy consumption. The system also aggregates the personal car data from all of the site’s users anonymously so people can share their fuel economy estimates. “You can track your car’s fuel economy over time to see if your efforts to increase MPG are working,” says David Greene, research staffer at Oak Ridge National Lab. “Then you can compare your fuel data with others and see how you are doing relative to those who own the same vehicle.”
  • In the works for the site is a predictive tool you can use when you are in the market for a new or used vehicle to more accurately predict the kind of mileage any given car will give you, based on your particular driving style and conditions. The system, says Greene, reduces the +/- 7 mpg margin of error of standard EPA ratings by about 50% to give you a more accurate estimate of what your MPG will be.
  • Solar Decathlon
  • In response to the White House’s Startup America program supporting innovation and entrepreneurship, the Energy Department launched its own version — America’s Next Top Energy Innovator Challenge. The technology transfer program gives startups the chance to license Energy Department technologies developed at the 17 national laboratories across the country at an affordable price. Entrepreneurs can identify Energy Department technologies through the Energy Innovation Portal, where more than 15,000 patent and patent applications are listed along with more than 450 market summaries describing some of the technologies in layman’s terms.
  • 2. America’s Next Top Energy Innovator
  • 3. Products: Smarter Windows
  • DOE funding, along with private investments, supports a number of companies including the Michigan-based company Pleotint. Pleotint developed a specialized glass film that uses energy generated by the sun to limit the amount of heat and light going into a building or a home. The technology is called Sunlight Responsive Thermochromic (SRT™), and it involves a chemical reaction triggered by direct sunlight that lightens or darkens the window’s tint. Windows made from this glass technology are designed to change based on specific preset temperatures.
  • Another DOE-funded company, Sage ElectroChromics, created SageGlass®, electronically controlled windows that use small electric charges to switch between clear and tinted windows in response to environmental heat and light conditions. And Soladigm has an electronic tinted glass product that is currently undergoing durability testing.
  • Once a company selects the technology of interest to them, they fill out a short template to apply for an option — a precursor to an actual license of the patent — for $1,000. A company can license up to three patents on one technology from a single lab per transaction, and patent fees are deferred for two years. The program also connects entrepreneurs to venture capitalists as mentors.
  • Since 2002, the U.S. Department of Energy’s Solar Decathlon has challenged collegiate students to develop solar-powered, highly efficient houses. Student teams build modular houses on campus, dismantle them and then reassemble the structures on the National Mall. The competition has taken place biennially since 2005. Open to the public and free of charge, the next event will take place at the National Mall’s West Potomac Park in Washington, D.C. from September 23 to October 2, 2011. There are 19 teams competing this year.
  • Teams spend nearly two years planning and constructing their houses, incorporating innovative technology to compete in 10 contests. Each contest is worth 100 points to the winner in the areas of Architecture, Market Appeal, Engineering, Communications, Affordability, Comfort Zone, Hot Water, Appliances, Home Entertainment and Energy Balance. The team with the most points at the end of the competition wins.
  • Since its inception, the Solar Decathlon has seen the majority of the 15,000 participants move on to jobs related to clean energy and sustainability. The DOE’s digital strategy for the Solar Decathlon includes the use of QR codes to provide a mobile interactive experience for visitors to the event in Washington, D.C., as well as Foursquare checkin locations for the event and for each participating house. Many of the teams are already blogging leading up to the event and there are virtual tours and computer animated video walkthroughs to share the Solar Decathlon experience with a global audience. There will be TweetChats using the hashtag #SD2011 and other activities on Twitter, Facebook, Flickr and YouTube.
  • The Future
  • In terms of renewable energies, the DOE tries to stay on the cutting edge. Some of their forward-thinking projects include the Bioenergy Knowledge Discovery Framework (KDF), containing an interactive database toolkit for access to data relevant to anyone engaged with the biofuel, bioenergy and bioproduct industries. Another is an interactive database that maps the energy available from tidal streams in the United States. The database, developed by the Georgia Institute of Technology in cooperation with the Energy Department, is available online. The tidal database gives researchers a closer look at the potential of tidal energy, which is a “predictable” clean energy resource. As tides ebb and flow, transferring tidal current to turbines to become mechanical energy and then converting it to electricity. There are already a number of marine and hydrokinetic energy projects under development listed on the site.

Fukushima's Contamination Produces Some Surprises at Sea [29Sep11] - 0 views

  • Six months after the accident at Fukushima Daiichi, the news flow from the stricken nuclear power plant has slowed, but scientific studies of radioactive material in the ocean are just beginning to bear fruit.The word from the land is bad enough. As my colleague Hiroko Tabuchi reported on Saturday, Japanese officials have detected elevated radiation levels in rice near the crippled reactors. Worrying radiation levels had already been detected in beef, milk, spinach and tea leaves, leading to recalls and bans on shipments.
  • Off the coast, the early results indicate that very large amounts of radioactive materials were released, and may still be leaking, and that rather than being spread through the whole ocean, currents are keeping a lot of the material concentrated. Most of that contamination came from attempts to cool the reactors and spent fuel pools, which flushed material from the plant into the ocean, and from direct leaks from the damaged facilities.
  • Working with a team of scientists from other institutions, including the University of Tokyo and Columbia University, Mr. Buesseler’s Woods Hole group in June spent 15 days in the waters off northeast Japan, studying the levels and dispersion of radioactive substances there and the effect on marine life.The project, financed primarily by the Moore Foundation after governments declined to participate, continued to receive samples from Japanese cruises into July.

  • The leakage very likely isn’t over, either. The Tokyo Electric Power Company, the operator of the plant, said Sept. 20 that it believed that something on the order of 200 to 500 tons a day of groundwater might still be pouring into the damaged reactor and turbine buildings.Ken Buesseler, a scientist at the Woods Hole Oceanographic Institution, who in 1986 studied the effects of the Chernobyl disaster on the Black Sea, said the Fukushima disaster appeared to be by far the largest accidental release of radioactive material into the sea.
  • Chernobyl-induced radiation in the Black Sea peaked in 1986 at about 1,000 becquerels per cubic meter, he said in an interview at his office in Woods Hole, Mass. By contrast, the radiation level off the coast near the Fukushima Daiichi plant peaked at more than 100,000 becquerels per cubic meter in early April.
  • Japanese government and utility industry scientists estimated this month that 3,500 terabecquerels of cesium 137 was released directly into the sea from March 11, the date of the earthquake and tsunami, to late May. Another 10,000 terabecquerels of cesium 137 made it into the ocean after escaping from the plant as steam.
  • While Mr. Buesseler declined to provide details of the findings before analysis is complete and published, he said the broad results were sobering.“When we saw the numbers — hundreds of millions of becquerels — we knew this was the largest delivery of radiation into the ocean ever seen,’’ he said. ‘‘We still don’t know how much was released.’’Mr. Buesseler took samples of about five gallons, filtered out the naturally occurring materials and the materials from nuclear weapon explosions, and measured what was left.
  • The scientists had expected to find ocean radiation levels falling off sharply after a few months, as radioactive substances were dispersed by the currents, because, he said, “The ocean’s solution to pollution is dilution.’’The good news is that researchers found the entire region 20 to 400 miles offshore had radiation levels too low to be an immediate threat to humans.But there was also an unpleasant surprise. “Rather than leveling off toward zero, it remained elevated in late July,’’ he said, up to about 10,000 becquerel per cubic meter. ‘‘That suggests the release problem has not been solved yet.”
  • The working hypothesis is that contaminated sediments and groundwater near the coast are continuing to contaminate the seas, he said.The international team also collected plankton samples and small fish for study. Mr. Buesseler said there were grounds for concern about bioaccumulation of radioactive isotopes in the food chain, particularly in seaweed and some shellfish close to the plants. A fuller understanding of the effect on fish that are commercially harvested will probably take several years of data following several feeding cycles, he said.
  • ‘We also don’t know concentrations in sediments, so benthic biota may be getting higher doses and if consumed (shellfish), could be of concern,’’ he wrote later in an e-mail, referring to organisms that dwell on the sea floor.The study also found that the highest cesium values were not necessarily from the samples collected closest to Fukushima, he said, because eddies in the ocean currents keep the material from being diluted in some spots farther offshore.The overall results were consistent with those previously found by Japanese scientists, Mr. Buesseler said.He said more research was urgently needed to answer several questions, including why the level of contamination offshore near the plant was so high.“Japan is leading the studies, but more work is needed than any one country, or any one lab, can possibly carry out,” he said.

Regulator signs off on threatened nuclear plant [27Jun11] - 0 views

  • A top regulator said on Sunday that a nuclear power plant threatened by flooding from the swollen Missouri River was operating safely and according to standards. "I got to see a lot of efforts they're taking to deal with flooding and the challenges that presents," Gregory Jaczko, the chairman of the federal Nuclear Regulatory Commission, said after touring the Cooper Nuclear Station near the village of Brownville and meeting with plant officials and executives.
  • Right now, we think they're taking an appropriate approach. This is a plant that is operating safely and meeting our standards," he added.The plant is located about 80 miles south of Omaha, where snow melt and heavy rains have forced the waters of the Missouri River over its banks, although they have not flooded the plant and receded slightly on Sunday.Jaczko said he was not doing an official plant inspection. He was briefed by NRC resident inspectors -- the agency staff who work on-site every day -- plant officials and executives, said Mark Becker, a spokesman at the Nebraska Public Power District, the agency that runs the plant.The power plant sat about 4 feet above the river's level on Sunday. The river had surged over its banks near the plant and filled in low-lying land near the Cooper plant.Water levels there are down after upstream levees failed, Becker said, relieving worries that water will rise around the Brownville plant as it has at another nuclear plant north of Omaha in Fort Calhoun.Art Zaremba, director of nuclear safety at Cooper, backed the assessment."The plant is very safe right now, and we've taken a lot of steps to make sure it stays that way," Zaremba said.
