Japan - check begins on 13 idled reactors [08Sep11] - 0 views

  • Thirteen of the nearly 30 reactors nationwide idled for regular checks have entered the first stage of the safety evaluation process, one of the conditions for restarting them following the Fukushima nuclear crisis, sources said Wednesday.
  • Kansai Electric Power Co. and Shikoku Electric Power Co. plan to submit evaluation reports on their six idled reactors to the Nuclear and Industrial Safety Agency by the end of this month. The other four utilities hoping to restart the remaining seven reactors are also accelerating their efforts, aiming to resume operations of their units as early as the end of the year
  • The stress tests were set up by the government in July as a precondition for restarting reactors following the crisis at the Fukushima No. 1 power plant. Prime Minister Yoshihiko Noda has shown support for restarting idled reactors to ensure a stable supply of electricity. However, it remains uncertain whether local governments will give their approval to restart reactors, another requirement for their resumption. The 13 reactors are units 1 and 2 at Hokkaido Electric Power Co.'s Tomari plant; the No. 1 unit at Tohoku Electric Power Co.'s Higashidori plant; the No. 2 unit at Hokuriku Electric Power Co.'s Shiga plant; Kansai Electric's units 1 and 3 at its Mihama plant and units 1 and 3 at its Oi plant as well as the No. 1 unit at its Takahama plant; the No. 3 unit at Shikoku Electric's Ikata plant; and Kyushu Electric Power Co.'s units 2 and 3 at its Genkai plant and the No. 1 unit at its Sendai plant

  • "The market's background radiation was said to be about 39 CPMs. The two peaches, thus, had significantly high radiation contamination equaling over two times site background levels," stated reported EnviroReporter, the  independent news source created by Michael Collins and Denise Anne Duffield in May 2006 featuring work of Collins, a multi-award-winning investigative journalist who specializes in environmental issues and served sic years as a Director of the Los Angeles Press Club and five years as its Judging Chair
  • "What makes this discovery especially significant is that the 2X background radioactivity detected in these peaches was likely significantly attenuated by their water content; when eaten the exposure rate may be significantly higher.

U.S. secretly asked Japan to help dump nuclear reactors [27Sep11] - 0 views

  • The United States secretly sought Japan's support in 1972 to enable it to dump decommissioned nuclear reactors into the world's oceans under the London Convention, an international treaty being drawn up at the time. Countries working on the wording of the pact wanted to specifically prohibit the dumping of radioactive waste at sea.
  • But Washington wanted to incorporate an exceptional clause in the case of decommissioned nuclear reactors. These facts came to light in diplomatic records held by the Foreign Ministry in Tokyo and released at the request of The Asahi Shimbun.
  • The documents obtained by The Asahi Shimbun were signed by Japan's ambassador to Britain and designated as top secret. According to the records, a U.S. State Department official who was part of the U.S. delegation discussing the terms of the treaty, met his Japanese counterpart in November 1972. In that meeting, the official explained that the United States had a number of early-stage nuclear reactors which had reached their life spans. He said Washington was facing problems disposing of them.
  • ...6 more annotations...
  • Since Japan, a key U.S. ally, had already started its own nuclear power generation program, Washington did not hesitate to seek Tokyo's backing for its request. It was apparent that the United States constructed nuclear reactors without having decided on disposal methods, forcing it to consider dumping them at sea after they were decommissioned.
  • Japan did not offer a clear answer when it was approached by the United States on the issue. Eventually, however, Washington succeeded in incorporating the clause into the treaty. In 1972, the United States was already dismantling early-stage nuclear reactors that had been used for testing. However, the disposal method of large-scale nuclear reactors for commercial purposes had not been decided although it was an issue that could not be shelved indefinitely.
  • The official noted that any attempt to bury the reactors on land would invite a public backlash. He also pointed to the financial difficulty of scientifically processing the reactors until the risk of radioactive contamination was totally eliminated. Then, the official said the only other option was to dump them at sea, and asked Japan for cooperation.
  • According to Kumao Kaneko, now aged 74 and then a member of the Foreign Ministry team involved in the negotiations, Japan did not take specific steps to assist the United States in this delicate matter. Eventually, during the general meeting of countries for the London Convention, the United States proposed incorporating a clause that would enable it to dump nuclear reactors at sea in exceptional cases in which all other means of disposal presented a risk to human health.
  • When presenting the proposal, the United States made no mention of its intention to dump its nuclear reactors at sea far into the future. The proposal was accepted. In the early 1970s, sea pollution was a huge international issue. Against that backdrop, countries worked feverishly to put the finishing touches on the London Convention. The treaty designated high-level radioactive substances as well as other materials, including mercury and cadmium, as waste whose dumping at sea is prohibited.
  • In 1993 revisions to the London Convention, the dumping of radioactive waste at sea was totally prohibited. However, the clause that approved of dumping in exceptional cases remained. For this reason, under the London Convention, it is possible for member countries of the treaty to dump radioactive waste at sea if they obtain the OK from the other parties as well as the International Atomic Energy Agency. According to the IAEA, the United States has not dumped radioactive waste at sea since 1970. Instead, it buries decommissioned nuclear reactors underground.

New Reactor in Tennessee: Safety Concerns Cloud US Nuclear Renaissance [22Jul11] - 0 views

  • Watts Bar 2, the US's newest nuclear power plant, is being built in Tennessee and is expected to go online next year. It has a history of safety concerns that goes back decades. Nevertheless, many local people support nuclear power and are welcoming the reactor with open arms.
  • Mansour Guity was the chief witness against the American nuclear industry. He crippled entire power plants almost single-handedly. But now the 30-year war he has been waging is coming to an end. They are now putting the finishing touches on the second reactor at the Watts Bar Nuclear Generating Station in the Tennessee River valley, less than 50 kilometers (31 miles) from Guity's house. After construction was stopped more than two decades ago and resumed in 2007, the reactor is now expected to go online next year. Mansour Guity isn't doing too well at the moment.
  • In the 1960s, 1970s and 1980s, he gradually discovered that so many shortcuts were taken, and some of the work was so shoddy, during the construction of the nuclear plants along the Tennessee River that it made a mockery of any notion of nuclear safety. Guity was a nuclear engineer at the Tennessee Valley Authority (TVA), a large, long-established government-owned company that operates the Browns Ferry, Sequoyah, Bellefonte and Watts Bar nuclear power plants. When the plants were built, there was talk of thousands of clear violations of plans and building regulations, with the most serious infractions occurring at Watts Bar.
  • ...6 more annotations...
  • A nuclear engineer who was born in Iran in 1942, Guity is a disappointed American today. "Time bombs," he says, sounding very bitter. "We are sitting on a bunch of ticking time bombs."
  • Not Up to Standard
  • The plant's two units were built at the same time in the 1970s and 80s. Only Unit 1 was placed into operation, after a dramatic delay, while Unit 2 remained unfinished until construction was resumed a few years ago. If Guity had his way, the entire plant, including both units and everything else associated with it, would disappear from the map as soon as possible.
  • The reason Guity still has trouble sleeping at night is his belief that all of these old mistakes and violations can never be completely corrected.
  • One of the reasons Guity is so upset is that there is no public debate in the United States over Watts Bar, or nuclear energy in general. It is a non-issue throughout the country, even though, according to Guity, there are plenty of reasons that it should be discussed. The United States has 104 nuclear reactors in operation, more than any other country in the world. Many plants are alarmingly dated -- some are 40 years old or even older. Some 65,000 tons of nuclear waste have accumulated over the decades. As unbelievable as it sounds, the country doesn't even have a long-term plan for the storage and disposal of the nuclear waste being generated every day.
  • If the second unit at Watts Bar, America's last reactor still under construction, really does go online next year, almost 40 years after building work began, parts of the unit will still date from the time when so many criteria were being violated. In fact, no one, not even the TVA, knows exactly the nature and scope of these violations.

Japan Nuclear Disaster Models From 2002 [26Aug11] - 0 views

  • A Japan Atomic Energy Institute paper from 2002 recently surfaced online. This paper was the technical estimations of what would happen if a nuclear reactor on the Pacific coast of Japan were to have a catastrophic accident. The models included radiation dispersal under a variety of scenarios and also illness and death rates under multiple scenarios. The plant for the experiment is  “1100MWe BWR5 with Mark-II type containment– One of the most common plant type in Japan“. Based on the location on the maps included in the paper the reactor used was either unit 6 at Fukushima Daiichi or one of units 1-4 at Fukushima Daini. The scenario is for one reactor failure, not 3 reactor failures plus spent fuel pools as was experienced at Fukushima Daiichi. Of the included reactor scenarios the one that closest resembles the Fukushima disaster is failure of cooling + overpressure damage. Below are two graphs, one in English, another in Japanese. They show the reactor damage scenarios, distance from the plant and mortality.
  • 20 km away will cause max. 1 out of 500 deaths, an exclusion zone of 100 km will cause max. 1 out of 5000 deaths. The diagram may explain the 20 km exclusion zone. all curves go down beond 20 km away from the plant. Acute deaths = deaths for direct exposure to NPP wave radiaton + explosion deaths. The two sharply-dropping lines on the Japanese chart show acute death. Please make note that at 100 Km. distance values are not 0. Moreover X axis is logarithmic. Tokio-Fuku distance= 230 Km. Our estimate for 230 Km. death rate ~ 10*-4.Tokio Metropolis population 34,500,000 (2007)34500000/10000.  3450 deaths in Tokio only. Again, this is based on this model scenario, not exact situations currently going on. These mortality models include late onset cancers and also survivable cancers based on the details in the report.
  • Some interpretations of the data in this report using the closest to Fukushima Daiichi model available. These do not mean specifically these things will happen, this is what the model shows under the scenario details they used: The model used does not differentiate between a unit 2 style containment failure and a unit 3 or Chernobyl style containment failure. A containment failure can vary greatly in how much of the nuclear fuel is released into the environment. The containment system in the model reactor is newer, technically improved and larger than the containment used in units 1-4 at Fukushima Daiichi. Unit 1 at Fukushima Daiichi has a slightly smaller containment than units 2-4. There have been concerns expressed that the smaller containment had less volume, making it more prone to failure. These slight differences in the reactors would result in changes to the amount of radiation released and would then change all these other outcomes.

  • There’s the MOX factor to consider too, the addition of MOX fuel is not included in the model. MOX fuel in reactor 3 may have played a role in the speed of the meltdown and adds plutonium and related isotopes into the releases different than what would be seen with uranium fuel. The report in English, includes a series of PowerPoint slides at the end. *This report also talks at length about ways radiation is absorbed by people, they may not be included in the Japanese language report.

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.

Oldbury 1 to shut down in early 2012 [23Oct11] - 0 views

  • After 44 years of operation, unit 1 of the UK's Oldbury nuclear power plant will be permanently shut down in February 2012, ten months earlier than expected, Magnox Ltd announced.
  • The company said that further operation of the 217 MWe Magnox reactor was "no longer economically viable." The decision to shut down the unit - the only operational reactor at the site - was taken "after careful consideration by operators Magnox and the site owners the Nuclear Decommissioning Authority (NDA), in conjunction with independent regulators the Office for Nuclear Regulation (ONR)."   Built in the 1960s and among the first generation of UK reactors, both of the gas-cooled, graphite-moderated first generation reactors at Oldbury were originally scheduled to shut down at the end of 2008. However, the NDA requested permission from the regulator to operate beyond that date, earning revenue to help pay for decommissioning. While unit 2 was eventually shut down in June 2011, unit 1 was expected to close at the end of 2012. To date, the site has generated over 130 terawatt-hours (TWh) of electricity.  
  • Oldbury site director Phil Sprague said, "Oldbury's excellent generation history is a terrific success story, especially as the site was originally planned to close in 2008. As a result of excellent teamwork between Magnox, the NDA and ONR the site's operational life was extended until February 2012, and it is a testament to the skills and dedication of the workforce who have operated and maintained the reactors to such a high standard that it has been able to continue to generate safely."   Magnox Ltd noted that since their originally planned shut down date of 2008, the two units have generated an additional 7 TWh, worth an estimated £300 million ($478 million) to the British taxpayer. This extra generation, it added, also saved some six million tonnes of carbon from being released into the atmosphere.   NDA executive director for delivery Mark Lesinski commented: "The income from electricity sales has provided an important contribution to the funding for our decommissioning program. Magnox and NDA will now work with stakeholders to ensure a smooth transition into the next stage for the site which will involve defueling and subsequent decommissioning."
  • ...1 more annotation...
  • Under current plans, the operation to remove the fuel from both units should be completed in 2013. After most of the structures at Oldbury have been removed, the site will enter the 'care and maintenance' stage of decommissioning around 2027, after which the reactor is left to cool. Final site clearance activities are scheduled between 2092 and 2101.   The last two remaining Magnox reactors currently in operation in the UK are at Wylfa site. The two 490 MWe units there are scheduled to shut down at the end of 2012.   Horizon Nuclear Power - a 50-50 joint venture between RWE nPower and EOn UK - plans to submit a planning application for a new nuclear power plant at Oldbury around 2014. According to the company, "Given the right market conditions, and subject to a final investment decision, preliminary works could begin in 2016, followed by main construction from 2019." Horizon is yet to decide which of the two available reactor designs - Areva's EPR or Westinghouse's AP1000 - it would like to build.

95% disagree with "Beyond Nuclear". Let's make it 99% [23Oct11] - 0 views

  • Perhaps this October 12, 2011 post titled Oyster Creek Response that was published on Clean Energy Insight has something to do with the way the results are shaping up with 1029 out of 1080 respondents (95.3%) saying that Oyster Creek should not stop operating. Here is one more example of how inbred the group of antinuclear activists has become. I am talking here about the people who are so adamantly opposed to using nuclear energy that they do not even want existing nuclear plants to keep on producing clean, emission free, low cost electricity. Michael Mariotte of NIRS makes the following extraordinary claim: Ninety-five percent of the people in the world know about Fukushima, Michael Mariotte of the Nuclear Information and Resource Service said.

  • NOTHING happend to the fuel in the pools at Fukushima. I would like to see some evidence other than the word of an activist who frightens kids for a living to support Gunter’s rant about peices of fuel being ejected miles away. From the looks of that video, the fuel didn’t move an inch. There is also a poll associated with the article. The poll discloses that it is completely unscientific, since it allows anyone to vote and is not based on randomly selected participants. However, I think that the results as of 0315 this morning are pretty amusing since the antinuclear opinion piece has been posted for nearly a week.

Something has to be done to make sure that never happens again.” I could not let that one pass without a comment; I am quite sure that Mariotte has once again fallen victim to the fact that he surrounds himself with people who echo his own prejudices. Here is my response.
  • Marriotte makes an interesting statement by he claiming that “95% of the people in the world” know about Fukushima. That statement might be true about the people in the United States, where advertiser-supported television news programs covered the events with breathless hype for several months. I am pretty sure that you would have a difficult time finding anyone in China, central Africa, the Asian subcontinent, South America or the Middle East who can even pronounce Fukushima, much less know anything about GE Mark 1 containments. Most of them would not even know that they should be worried about radiation because they have never been taught to be afraid of something that they cannot smell, feel, taste, or hear especially when it occurs at levels that have no chance of making them sick within their expected lifetime. Mariotte, Gunter, Kamps, Katz and Bridenbaugh are all members of a vocal, but tiny group of people who have been carrying the water of the fossil fuel industry for decades by opposing nuclear energy, the only real competitor it has. They are victims of groupthink who believe that their neighbors in Takoma Park are representative of the whole world.
  • Just before making this comment, I voted in the unscientific poll associated with the article. 95% say that Oyster Creek should keep on powering New Jersey homes and businesses. They are not impressed by the Beyond Nuclear FUD; they like clean electricity.

    Video - New TEPCO data measured on August 19 & 20 shows severe damage to the spent fuel in Fukushima Daiichi Units 1, 2, and 3. The adjacent TEPCO table posted on the front page shows incredibly high levels of Cesium 137 and Cesium 134 in all three spent fuel pools of Units 1, 2, & 3. This TEPCO data clearly contradicts and refutes the July assertion by the NRC the Fukushima Daiichi spent fuel pools were not damaged in this tragic accident. Crytome (cry to me) has a new high resolution photo, also uploaded, that shows the extensive damage of the Unit 3 spent fuel pool and the reactor building.

TEPCO : Press Release | Nuclide Analysis Results of Radioactive Materials in Seawater t... - 0 views

  • At around 9:30 am on April 2, 2011, we detected water containing radiation dose over 1,000 mSv/h in the pit* where power supply cables are stored near the intake channel of Unit 2. Furthermore, there was a crack of about 20 cm length on the concrete lateral of the pit, from where the water in the pit was flowing out to the ocean. At around 12:20 pm on April 2, we reaffirmed the event at the scene. We have implemented sampling of the water in the pit of Unit 2, together with the seawater in front of the bar screen near the pit of Unit 2. These samples were sent to Fukushima Daini Nuclear Power Station for analyses. At around 5:38 am on April 6, we observed stoppage of spilling of water to the ocean from the crack on the concrete lateral of the pit.
  • On May 11, 2011, responding to out-flow leakage of contaminated water from the intake canal of Unit 3, from May 12th, we additionally conducted the sampling of the seawater inside and outside of the silt fence in front of the bar screen near the pit of Unit 1, 3 and 4. (Previously announced) On September 22, 2011, we conducted sampling of the seawater near the intake canal of Units 1 to 4 of Fukushima Daiichi Nuclear Power Station and analyzed the samples. As a result, some radioactive materials were detected as described in the appendix. We informed Nuclear and Industrial Safety Agency (NISA) and the government of Fukushima Prefecture of the results above today. We will continue to conduct same kind of samplings. * Pit: vertical shaft made of concrete

Nuclear generation rise in 2010 [15Jun11] - 0 views

  • The total amount of electricity generated by nuclear powers plants around the world increased in 2010 following three consecutive years of decline. However, a sharp drop in output is foreseen for 2011 as a result of the Fukushima accident.    Global nuclear electricity generation in 2010 totalled 2630 TWh, according to figures from the International Atomic Energy Agency (IAEA), representing a 2.8% increase from the 2558 TWh generated in 2009 and taking it close to a peak value in 2006. The energy availability factor of the plants operating in 2010 was 81%, up from 79.4% in 2009.
  • New reactors amounting to 3722 MWe net boosted the 2010 figure, including Russia's Rostov 2, India's Rajasthan 6, China's Ling Ao 3 and Qinshan II-3, and South Korea's Shin Kori 1.   Just one small reactor - France's 130 MWe Phenix prototype fast reactor - was officially shut down in 2010, although the unit actually ceased power generation in 2009.
  • Construction of 16 new reactors, with a combined capacity of 15,846 MWe net, started in 2010, according to the IAEA. Ten of these are in China (Ningde units 3 and 4, Taishan 2, Changjiang 1 and 2, Haiyang 2, Fangchenggang 1 and 2, Yangjiang 3 and Fuqing 3). In Russia, the construction of two new units also began (Leningrad II unit 2 and Rostov 4), while two more started construction in India (Kakrapar 3 and 4). In Brazil, work also started on building the Angra 3 unit. Meanwhile, the stalled construction of Japan's 1383 MWe Ohma unit also got back underway in 2010 after re-engineering work for enhanced earthquake protection.
  • ...4 more annotations...
  • Assuming about five years for construction it can be expected that reactors will be coming online around 2012 at double today's rate of five per year, with this to rise to one per month around 2015.
  • Fukushima impact
  • Despite a return to form for nuclear power in 2010, the impact of the Fukushima accident, not only in Japan but around the world, will significantly reduce the amount of electricity generated by nuclear power plants in 2011.
  • According to data released by the Japan Atomic Industry Forum (JAIF), only 17 of Japan's 54 nuclear power reactors were in operation in mid-May. They represented around 15,500 MWe, or 31%, of the country's total nuclear generating capacity.

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.

Is nuclear energy different than other energy sources? [08Sep11] - 0 views

  • Nuclear power proponents claim: It has low carbon emissions. It is the peaceful face of the atom and proliferation problems are manageable. It is compact -- so little uranium, so much energy. Unlike solar and wind, it is 24/7 electricity. It reduces dependence on oil. Let's examine each argument.
  • 1. Climate. Nuclear energy has low carbon emissions. But the United States doesn't lack low-carbon energy sources: The potential of wind energy alone is about nine times total US electricity generation. Solar energy is even more plentiful. Time and money to address climate change are in short supply, not low carbon dioxide sources. Instead of the two large reactors the United States would require every three months to significantly reduce carbon dioxide emissions, all the breathless pronouncements from nuclear advocates are only yielding two reactors every five years -- if that. Even federal loan guarantees have not given this renaissance momentum. Wall Street won't fund them. (Can nuclear power even be called a commercial technology if it can't raise money on Wall Street?) Today, wind energy is far cheaper and faster than nuclear. Simply put: Nuclear fares poorly on two crucial criteria -- time and money.
  • 2. Proliferation. President Eisenhower spoke of "Atoms for Peace" at the United Nations in 1953; he thought it would be too depressing only to mention the horrors of thermonuclear weapons. It was just a fig leaf to mask the bomb: Much of the interest in nuclear power is mainly a cover for acquiring bomb-making know-how. To make a real dent in carbon dioxide emissions, about 3,000 large reactors would have to be built worldwide in the next 40 years -- creating enough plutonium annually to create 90,000 bombs, if separated. Two or three commercial uranium enrichment plants would also be needed yearly -- and it has only taken one, Iran's, to give the world a nuclear security headache.
  • ...3 more annotations...
  • 4. Consistency. Solar and wind power are intermittent. But the wind often blows when the sun doesn't shine. Existing hydropower and natural gas plants can fill in the gaps. Denmark manages intermittency by relying on Norwegian hydropower and has 20 percent wind energy. Today, compressed-air energy storage is economical, and sodium sulfur batteries are perhaps a few years from being commercial. Smart grids and appliances can communicate to alleviate intermittency. For instance, the defrost cycle in one's freezer could, for the most part, be automatically deferred to wind or solar energy surplus periods. Likewise, icemakers could store coldness to provide air-conditioning during peak hot days. The United States is running on an insecure, vulnerable, 100-year-old model for the grid -- the equivalent of a punch-card-mainframe computer system in the Internet age. It's a complete failure of imagination to say wind and solar intermittency necessitates nuclear power.
  • 3. Production. Nuclear power does produce electricity around the clock -- until it doesn't. For instance, the 2007 earthquake near the seven-reactor Kashiwazaki Kariwa plant in Japan turned 24/7 electricity into a 0/365 shutdown in seconds. The first of those reactors was not restarted for nearly two years. Three remain shut down. Just last month, an earthquake in Virginia shut down the two North Anna reactors. It is unknown when they will reopen. As for land area and the amount of fuel needed, nuclear proponents tend to forget uranium mining and milling. Each ton of nuclear fuel creates seven tons of depleted uranium. The eight total tons of uranium have roughly 800 tons of mill tailings (assuming ore with 1 percent uranium content) and, typically, a similar amount of mine waste. Nuclear power may have a much smaller footprint than coal, but it still has an enormous waste and land footprint once uranium mining and milling are considered.
  • 5. Oil. The United States uses only a tiny amount of oil in the electricity sector. But with electric vehicles, solar- and wind-generated electricity can do more for "energy independence" now than nuclear can, as renewable energy plants can be built quickly. Luckily, this is rapidly becoming a commercial reality. Parked electric vehicles or plug-in hybrids in airports, large businesses, or mall parking lots could help solve intermittency more cheaply and efficiently. Ford is already planning to sell solar panels to go with their new all-electric Ford Focus in 2012. We don't need a costly, cumbersome, water-intensive, plutonium-making, financially risky method to boil water. Germany, Italy, and Switzerland are on their way to non-nuclear, low-carbon futures. Japan is starting down that road. A new official commission in France (yes, France!) will examine nuclear and non-nuclear scenarios. So, where is the Obama administration?

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.

Wondering why still no radiation casualties at Fukushima? A prominent radiation epidemi... - 0 views

  • It has been 208 days since the Fukushima nuclear meltdown. The casualty count from atomic radiation is today exactly what it was the day before the Great East Japan Earthquake launched a tsunami that killed thousands and wrecked three reactors at the nuclear plant. That is, the number of radiation casualties is still zero. On May 13, sixty-three days after the quake and tsunami hit, John Boice, a professor of Radiation Epidemiology at Vanderbilt University, told a U.S. congressional committee why.
  • This is something that a lot of people (including me; see article) predicted on the first day of the nuclear situation. Nuclear meltdowns have never lived up to their pop-culture billing. The three major meltdowns in the history of the nuclear age—Chalk River in 1952, Three Mile Island in 1979, and of course Fukushima—resulted in zero casualties and negligible environmental damage. This is because they simply did not release enough radiation to kill anyone or harm the environment. Nevertheless, the term “nuclear meltdown” holds irresistible drawing power for media headline writers. Why is this? Because very few people understand nuclear radiation, much less its units of measure. So when faced with a barrage of reporting about radiation measurements—expressed in terms of picocuries, becquerels, rads, and microsieverts—most people have no way of evaluating that information. Therefore it all sounds kind of scary.
  • This may be why Dr. Boice also told the representatives this: There is a pressing need to learn more about the health consequences of radiation in humans when exposures are spread over time at low levels and not received briefly at high doses such as in atomic bomb survivors. When he gives radiation measurements, Dr. Boice oscillates between common and international (SI) units. When describing radioactivity, e.g. in bananas, he uses becquerels (SI units). When describing absorbed dose measurements, Dr. Boice uses millirems, which are common units. Most people use sieverts to describe absorbed dose. To convert millirems to microsieverts, multiply by ten. Click here for an excellent web-based radiation unit coverter.

  • Reading Dr. Boice’s testimony will take around ten minutes of your time. It is well worth your while. Here is part of Dr. Boice’s summary: The lasting effects [of the Fukushima meltdown] upon the Japanese population will most likely be psychological with increased occurrence of stress-related mental disorders and depression associated not necessarily with the concern about reactor radiation, but with the horrific loss of life and disruption caused by the tsunami and earthquake. In the headline-driven hysteria that has characterized coverage of the Fukushima issue, the tens of thousands killed and hundreds of thousands made homeless by the quake and tsunami have been all but forgotten by the western media.

Major Study: Reactor No. 5 releases may explain why so much radioactive xenon... - 0 views

  • “Fortunately, due to the maintenance outage and the survival of one diesel generator, it seems that unit 5 reactor cores as well as spent fuel ponds have not suffered major fuel damage,” says the study. Though, Reactor No. 5 is mentioned again several pages later: “Total a posteriori [experienced levels] 133Xe emissions are 16.7 EBq, one third more than the a priori value [predicted levels] of 12.6 EBq (which is equal to the estimated inventory) and 2.5 times the estimated Chernobyl source term of 6.5 EBq.
  • If there was only 12.6 EBq of xenon-133 inventory that could be emitted from reactors 1-3 and spent fuel pool No. 4 — yet 16.7 EBq was experienced — where did the extra xenon come from, according to the study? “There is the possibility of additional releases from unit 5.” Another possibility is that recriticality has occurred in one of the reactor units. The study says the a priori emissions could have been overestimated, but discounts the notion that the initial 12.6 EBq figure so poorly underestimated the amount of xenon in Reactors 1-3 and SFP 4, “It is unlikely that the 133Xe inventories of the reactor units 1–3 were one third higher than estimated.”

Damage to both reactor units? | unit, reactor, plant - Nuclear leak [03Feb12] - 0 views

  • As workers began inspecting a leaky tube in one of the San Onofre nuclear plant's reactors Thursday, federal regulators said more than 800 tubes in a second, offline reactor showed wear and thinning, although they are only two years old.And plant officials confirmed that sensors showed a tiny amount of radioactive gas may have leaked out of a building next to the first reactor before the reactor was shut down late Tuesday.
  • All four of the plant's steam generators and their tubes are about two years old, installed after being delivered to the West Coast by the Japanese manufacturer of the generators, Mitsubishi Heavy Industries.Some 9,700 tubes carry water from the reactor and through each generator."They have inspected 80 percent of the tubes in one of the steam generators at unit 2," said Victor Dricks, spokesman for the Nuclear Regulatory Commission. "Two of the tubes have thinning so extensive that they need to be plugged and taken out of service. Sixty nine other tubes have thinning greater than 20 percent of the wall thickness, and a larger number have thinning greater than 10 percent of wall thickness."The tubes with 10 percent thinning number more than 800, he said.

San Onofre nuclear power plant unit shut down after potential leak [30Jan12] - 0 views

  • Officials at the San Onofre nuclear power plant shut down one of the facility's two units Tuesday evening after a sensor detected a possible leak in a steam generator tube.The potential leak was detected about 4:30 p.m., and the unit was completely shut down about an hour later, Southern California Edison said. "The potential leak poses no imminent danger to the plant workers or the public," utility spokeswoman Jennifer Manfre told The Times. She said there were no evacuations and that crews were assessing the situation to determine if a leak had occurred.
