Spent Nuclear Fuel Reprocessing Facilities, Reulations [10Jun11] - 0 views

  • The NRC has the authority under the Atomic Energy Act to license commercial spent fuel reprocessing facilities. Currently, Title 10 of the Code of Federal Regulations (10 CFR) Part 50, ``Domestic Licensing of Production and Utilization Facilities,'' provides the licensing framework for production and utilization facilities. Although a reprocessing facility is one type of production facility, its industrial processes are more akin to fuel cycle processes. This framework was established in the 1970's to license the first U.S. reprocessing facilities. The policy decision by the Carter Administration to cease reprocessing initiatives was based, in part, on the proliferation risks posed by the early reprocessing technology. While that policy was reversed during the Reagan Administration, until recently there was no commercial interest in reprocessing and, hence, no need to update the existing reprocessing regulatory framework in 10 CFR part 50.
  • Although commercial reprocessing interest waned, the Department of Energy (DOE) continued to pursue reprocessing technology development through the National Laboratories. The DOE has sought to decrease proliferation risk and spent fuel high-level waste through developing more sophisticated reprocessing technologies. During the Bush Administration, the Global Nuclear Energy Partnership (GNEP) renewed interest in commercial reprocessing. The GNEP sought to expand the use of civilian nuclear power globally and close the nuclear fuel cycle through reprocessing spent fuel and deploying fast reactors to burn long-lived actinides. In response to these initiatives, the Commission directed the staff to complete an analysis of 10 CFR part 50 to identify regulatory gaps for licensing an advanced reprocessing facility.
  • In mid-2008, two nuclear industry companies informed the NRC of their intent to seek a license for a reprocessing facility in the U.S. An additional company expressed its support for updating the regulatory framework for reprocessing, but stopped short of stating its intent to seek a license for such a facility. At the time, the NRC staff also noted that progress on some GNEP initiatives had waned and it appeared appropriate to shift the focus of the NRC staff's efforts from specific GNEP-facility regulations to a more broadly applicable framework for commercial reprocessing facilities.

  • In SECY-08-0134, the staff discussed the shift in its approach to developing the regulatory framework for commercial reprocessing facilities. The staff noted that it would defer additional work on regulatory framework development efforts for advanced recycling reactors and focus on the framework revisions necessary to license a commercial reprocessing facility. As a result of this shift, an additional review of the initial gap analysis was warranted. The NRC staff further refined the regulatory gap analysis by focusing on commercial reprocessing and recycling using existing reactor technology. The staff summarized this analysis in SECY-09-0082. The staff's gap analysis identified 14 ``high'' priority gaps that must be resolved to establish an effective and efficient regulatory framework. The NRC staff's regulatory gap analysis considered several documents in its analysis, including: NUREG-1909, a white paper authored by the Advisory Committee on Nuclear Waste and Materials, titled ``Background, Status and Issues Related to the Regulation of Advanced Spent Nuclear Fuel Recycle Facilities,'' issued June 2008; correspondence from the Union of Concerned Scientists titled, ``Revising the Rules for Materials Protection, Control and Accounting;'' and a Nuclear Energy Institute white [[Page 34009]] paper titled, ``Regulatory Framework for an NRC Licensed Recycling Facility.''

Unstoppable leakage of medical staff in Fukushima [24Nov11] - 0 views

  • Japanese government lifted evacuating area from Minami soma shi on 9/30/2011. However,about 30,000 of 71500 people have not come back yet. Medical staff escaped too. Hospitals are suffering from shortage of man power though they should evacuate actually. Minamisoma city hospital is one of the major hospitals ,where is only 23 km from the Fukushima plants.
  • In this hospital ,doctors and nurse evacuated too. Full time doctor ; 14 → 8 Nurse ; 136 → 100 Beds ; 230 → 100 Apart from Minami soma city hospital , 2 of 8 hospitals were closed , 13 of 39 clinics were closed too.
  • There were about 900 medical staff but now it’s only 300 in total. Remaining medical staff are thinking that’s because the national support is not enough. Fukushima local government therefore has decided to spend 2 billion of 12 billion yen of tax allocation grant for medical care on these areas. It will be spent to re-employ evacuated doctors or hire new doctors.

  • Fukushima local government can not let citizens leak out of the boarder because they lose their tax income. Thus they try to keep the citizens remaining in the area to keep paying tax.
  • Yamashita Shunichi rejected to conduct blood test and urine test for Fukushima children , he decided to do only echo screening test though it does never work until the children actually have tumor ,which is likely in 4~5 years from now.

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

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

'Very Strange': Fukushima worker concerned about withdrawal from plant - Japan nuke com... - 0 views

  • Actual Fukushima worker concerns about sub-contract companies’ withdrawal, Fukushima Diary, January 5, 2012 [Emphasis Added]:
  • An Actual Fukushima worker, Happy20790, stated one of the worst risks about the plants on his tweets on 12/30/2011.
  • @Happy20790 Not even trying to come up with a good reason, major nuclear companies in japan, are starting to shift their staff away from 1F to other plants. Since building new reactors in Japan seems problematic right now, they start to focus on plants from foreign countries

  • @Happy20790 As usual, problems with water decontamination continue on site. i wish we could soon switch to permanent gear.. how long will it still be ok with all that temporary pipes and stuffs. what i’m being most afraid of is that general contractor and plant maker may decide to either reduce the amount of work done at fukushima daiichi (1F) or even worse, decide to evacuate the facility and stop employing people altogether.
  • @Happy20790 Despite Fukushima Daiichi plant still being in such a grave state, shifting staff away now, while work toward recovery is still taking place, looks very strange. Thinking that even at best times, there was simply just not enough capable hands.. [...]

Vancouver Aquarium 'alarmed' at mass die-off of starfish on B.C. ocean floor [07Oct13] - 0 views

  •  
    [...] aquarium staff don't know just how far-reaching the "alarming" epidemic has been, and whether this and other sea star species will recover. "They're gone. It's amazing," said Donna Gibbs, a research diver and taxonomist on the aquarium's Howe Sound Research and Conservation group. "Whatever hit them, it was like wildfire and just wiped them out." [...] Aquarium staff don't know the cause because they have had trouble gathering specimens for testing, as starfish that looked healthy in the ocean turned up as goo at the lab. [...] "We're just not sure yet if it's all the same thing," Gibbs said. "They're dying so fast." [...] The collaboration came about after a graduate student collected starfish for a research project and then watched as they "appeared to melt" in her tank. [...] Global News, Oct. 3, 2013: [...] starfish wasting or completely disintegrating ever since early September. "Now they are gone. They have disintegrated, and now there is just goo left," says research diver and taxonomist Donna Gibbs. "So we are trying to see as much as we can really fast and get reports from divers in other areas to see how widespread this is." […] "It is shocking to see them all dead. They are just gone. And, are they coming back? We want them back. B.C. is known for its sea stars. We have more species here than anywhere else in the world." [...]

CPS must die [24Oct07} - 0 views

  • Collectively, Texas eats more energy than any other state, according to the U.S. Department of Energy. We’re fifth in the country when it comes to our per-capita energy intake — about 532 million British Thermal Units per year. A British Thermal Unit, or Btu, is like a little “bite” of energy. Imagine a wooden match burning and you’ve got a Btu on a stick. Of course, the consumption is with reason. Texas, home to a quarter of the U.S. domestic oil reserves, is also bulging with the second-highest population and a serious petrochemical industry. In recent years, we managed to turn ourselves into the country’s top producer of wind energy. Despite all the chest-thumping that goes on in these parts about those West Texas wind farms (hoist that foam finger!), we are still among the worst in how we use that energy. Though not technically “Southern,” Texans guzzle energy like true rednecks. Each of our homes use, on average, about 14,400 kilowatt hours per year, according to the U.S. Energy Information Administration. It doesn’t all have to do with the A/C, either. Arizonans, generally agreed to be sharing the heat, typically use about 12,000 kWh a year; New Mexicans cruise in at an annual 7,200 kWh. Don’t even get me started on California’s mere 6,000 kWh/year figure.
  • Let’s break down that kilowatt-hour thing. A watt is the energy of one candle burning down. (You didn’t put those matches away, did you?) A kilowatt is a thousand burnin’ candles. And a kilowatt hour? I think you can take it from there. We’re wide about the middle in Bexar, too. The average CPS customer used 1,538 kilowatt hours this June when the state average was 1,149 kWh, according to ERCOT. Compare that with Austin residents’ 1,175 kWh and San Marcos residents’ 1,130 kWh, and you start to see something is wrong. So, we’re wasteful. So what? For one, we can’t afford to be. Maybe back when James Dean was lusting under a fountain of crude we had if not reason, an excuse. But in the 1990s Texas became a net importer of energy for the first time. It’s become a habit, putting us behind the curve when it comes to preparing for that tightening energy crush. We all know what happens when growing demand meets an increasingly scarce resource … costs go up. As the pressure drop hits San Anto, there are exactly two ways forward. One is to build another massively expensive power plant. The other is to transform the whole frickin’ city into a de-facto power plant, where energy is used as efficiently as possible and blackouts simply don’t occur.
  • Consider, South Texas Project Plants 1&2, which send us almost 40 percent of our power, were supposed to cost $974 million. The final cost on that pair ended up at $5.5 billion. If the planned STP expansion follows the same inflationary trajectory, the price tag would wind up over $30 billion. Applications for the Matagorda County plants were first filed with the Atomic Energy Commission in 1974. Building began two years later. However, in 1983 there was still no plant, and Austin, a minority partner in the project, sued Houston Power & Lighting for mismanagement in an attempt to get out of the deal. (Though they tried to sell their share several years ago, the city of Austin remains a 16-percent partner, though they have chosen not to commit to current expansion plans).

  • CPS didn’t just pull nukes out of a hat when it went looking for energy options. CEO Milton Lee may be intellectually lazy, but he’s not stupid. Seeking to fulfill the cheap power mandate in San Antonio and beyond (CPS territory covers 1,566 square miles, reaching past Bexar County into Atascosa, Bandera, Comal, Guadalupe, Kendall, Medina, and Wilson counties), staff laid natural gas, coal, renewables and conservation, and nuclear side-by-side and proclaimed nukes triumphant. Coal is cheap upfront, but it’s helplessly foul; natural gas, approaching the price of whiskey, is out; and green solutions just aren’t ready, we’re told. The 42-member Nuclear Expansion Analysis Team, or NEAT, proclaimed “nuclear is the lowest overall risk considering possible costs and risks associated with it as compared to the alternatives.” Hear those crickets chirping?
  • NEAT members would hold more than a half-dozen closed-door meetings before the San Antonio City Council got a private briefing in September. When the CPS board assembled October 1 to vote the NRG partnership up or down, CPS executives had already joined the application pending with the U.S. Nuclear Regulatory Commission. A Supplemental Participation Agreement allowed NRG to move quickly in hopes of cashing in on federal incentives while giving San Antonio time to gather its thoughts. That proved not too difficult. Staff spoke of “overwhelming support” from the Citizen’s Advisory Board and easy relations with City staff. “So far, we haven’t seen any fatal flaws in our analysis,” said Mike Kotera, executive vice president of energy development for CPS. With boardmember and Mayor Phil Hardberger still in China inspecting things presumably Chinese, the vote was reset for October 29.
  • No one at the meeting asked about cost, though the board did request a month-by-month analysis of the fiasco that has been the South Texas Project 1&2 to be delivered at Monday’s meeting. When asked privately about cost, several CPS officers said they did not know what the plants would run, and the figure — if it were known — would not be public since it is the subject of contract negotiations. “We don’t know yet,” said Bob McCullough, director of CPS’s corporate communications. “We are not making the commitment to build the plant. We’re not sure at this point we really understand what it’s going to cost.” The $206 million outlay the board will consider on Monday is not to build the pair of 1,300-megawatt, Westinghouse Advanced Boiling Water Reactors. It is also not a contract to purchase power, McCullough said. It is merely to hold a place in line for that power.
  • It’s likely that we would come on a recurring basis back to the board to keep them apprised of where we are and also the decision of whether or not we think it makes sense for us to go forward,” said Larry Blaylock, director of CPS’s Nuclear Oversight & Development. So, at what point will the total cost of the new plants become transparent to taxpayers? CPS doesn’t have that answer. “At this point, it looks like in order to meet our load growth, nuclear looks like our lowest-risk choice and we think it’s worth spending some money to make sure we hold that place in line,” said Mark Werner, director of Energy Market Operations.
  • Another $10 million request for “other new nuclear project opportunities” will also come to the board Monday. That request summons to mind a March meeting between CPS officials and Exelon Energy reps, followed by a Spurs playoff game. Chicago-based Exelon, currently being sued in Illinois for allegedly releasing millions of gallons of radioactive wastewater beneath an Illinois plant, has its own nuclear ambitions for Texas. South Texas Project The White House champions nuclear, and strong tax breaks and subsidies await those early applicants. Whether CPS qualifies for those millions remains to be seen. We can only hope.
  • CPS has opted for the Super Honkin’ Utility model. Not only that — quivering on the brink of what could be a substantial efficiency program, CPS took a leap into our unflattering past when it announced it hopes to double our nuclear “portfolio” by building two new nuke plants in Matagorda County. The utility joined New Jersey-based NRG Energy in a permit application that could fracture an almost 30-year moratorium on nuclear power plant creation in the U.S.
  • After Unit 1 came online in 1988, it had to be shut down after water-pump shaft seared off in May, showering debris “all over the place,” according to Nucleonics Week. The next month two breakers failed during a test of backup power, leading to an explosion that sheared off a steam-generator pump and shot the shaft into the station yard. After the second unit went online the next year, there were a series of fires and failures leading to a half-million-dollar federal fine in 1993 against Houston Power. Then the plant went offline for 14 months. Not the glorious launch the partnership had hoped for. Today, CPS officials still do not know how much STP has cost the city, though they insist overall it has been a boon worth billions. “It’s not a cut-and-dried analysis. We’re doing what we can to try to put that in terms that someone could share and that’s a chore,” said spokesman McCollough. CPS has appealed numerous Open Records requests by the Current to the state Attorney General. The utility argues that despite being owned by the City they are not required to reveal, for instance, how much it may cost to build a plant or even how much pollution a plant generates, since the electricity market is a competitive field.
  • How do we usher in this new utopia of decentralized power? First, we have to kill CPS and bury it — or the model it is run on, anyway. What we resurrect in its place must have sustainability as its cornerstone, meaning that the efficiency standards the City and the utility have been reaching for must be rapidly eclipsed. Not only are new plants not the solution, they actively misdirect needed dollars away from the answer. Whether we commit $500 million to build a new-fangled “clean-coal” power plant or choose to feed multiple billions into a nuclear quagmire, we’re eliminating the most plausible option we have: rapid decentralization.
  • A 2003 study at the Massachusetts Institute of Technology estimates the cost of nuclear power to exceed that of both coal and natural gas. A U.S. Energy Information Administration report last year found that will still be the case when and if new plants come online in the next decade. If ratepayers don’t pay going in with nuclear, they can bet on paying on the way out, when virtually the entire power plant must be disposed of as costly radioactive waste. The federal government’s inability to develop a repository for the tens of thousands of tons of nuclear waste means reactors across the country are storing spent fuel in onsite holding ponds. It is unclear if the waste’s lethality and tens of thousands of years of radioactivity were factored into NEAT’s glowing analysis.
  • The federal dump choice, Nevada’s Yucca Mountain, is expected to cost taxpayers more than $60 billion. If it opens, Yucca will be full by the time STP 3&4 are finished, requiring another federal dump and another trainload of greenbacks. Just the cost of Yucca’s fence would set you back. Add the price of replacing a chain-link fence around, let’s say, a 100-acre waste site. Now figure you’re gonna do that every 50 years for 10,000 years or more. Security guards cost extra. That is not to say that the city should skip back to the coal mine. Thankfully, we don’t need nukes or coal, according to the American Council for an Energy-Efficient Economy, a D.C.-based non-profit that champions energy efficiency. A collection of reports released this year argue that a combination of ramped-up efficiency programs, construction of numerous “combined heat and power” facilities, and installation of on-site renewable energy resources would allow the state to avoid building new power plants. Texas could save $73 billion in electric generation costs by spending $50 billion between now and 2023 on such programs, according to the research group. The group also claims the efficiency revolution would even be good for the economy, creating 38,300 jobs. If ACEEE is even mostly right, plans to start siphoning millions into a nuclear reservoir look none too inspired.
  • To jump tracks will take a major conversion experience inside CPS and City Hall, a turning from the traditional model of towering plants, reels of transmission line, and jillions of dependent consumers. CPS must “decentralize” itself, as cities as close as Austin and as far away as Seattle are doing. It’s not only economically responsible and environmentally sound, but it is the best way to protect our communities entering what is sure to be a harrowing century. Greening CPS CPS is grudgingly going greener. In 2004, a team of consultants, including Wisconsin-based KEMA Inc., hired to review CPS operations pegged the utility as a “a company in transition.” Executives interviewed didn’t understand efficiency as a business model. Even some managers tapped to implement conservation programs said such programs were about “appearing” concerned, according to KEMA’s findings.
  • While the review exposed some philosophical shortcomings, it also revealed for the first time how efficiency could transform San Antonio. It was technically possible, for instance, for CPS to cut electricity demand by 1,935 megawatts in 10 years through efficiency alone. While that would be accompanied with significant economic strain, a less-stressful scenario could still cut 1,220 megawatts in that period — eliminating 36 percent of 2014’s projected energy use. CPS’s current plans call for investing $96 million to achieve a 225-megawatt reduction by 2016. The utility plans to spend more than four times that much by 2012 upgrading pollution controls at the coal-fired J.T. Deely power plant.
  • In hopes of avoiding the construction of Spruce 2 (now being built, a marvel of cleanliness, we are assured), Citizen Oversight Committee members asked KEMA if it were possible to eliminate 500 megawatts from future demand through energy efficiency alone. KEMA reported back that, yes, indeed it was possible, but would represent an “extreme” operation and may have “unintended consequences.” Such an effort would require $620 million and include covering 90 percent of the cost of efficiency products for customers. But an interesting thing happens under such a model — the savings don’t end in 2012. They stretch on into the future. The 504 megawatts that never had to be generated in 2012 end up saving 62 new megawatts of generation in 2013 and another 53 megawatts in 2014. With a few tweaks on the efficiency model, not only can we avoid new plants, but a metaphorical flip of the switch can turn the entire city into one great big decentralized power generator.
  • Even without good financial data, the Citizen’s Advisory Board has gone along with the plan for expansion. The board would be “pennywise and pound foolish” not to, since the city is already tied to STP 1&2, said at-large member Jeannie O’Sullivan. “Yes, in the past the board of CPS had been a little bit not as for taking on a [greater] percentage of nuclear power. I don’t know what their reasons were, I think probably they didn’t have a dialogue with a lot of different people,” O’Sullivan said.
  • For this, having a City-owned utility offers an amazing opportunity and gives us the flexibility to make most of the needed changes without state or federal backing. “Really, when you start looking, there is a lot more you can do at the local level,” said Neil Elliott of the ACEEE, “because you control building codes. You control zoning. You can control siting. You can make stuff happen at the local level that the state really doesn’t have that much control of.” One of the most empowering options for homeowners is homemade energy provided by a technology like solar. While CPS has expanded into the solar incentives field this year, making it only the second utility in the state to offer rebates on solar water heaters and rooftop panels, the incentives for those programs are limited. Likewise, the $400,000 CPS is investing at the Pearl Brewery in a joint solar “project” is nice as a white tiger at a truck stop, but what is truly needed is to heavily subsidize solar across the city to help kickstart a viable solar industry in the state. The tools of energy generation, as well as the efficient use of that energy, must be spread among the home and business owners.
  • Joel Serface, with bulb-polished pate and heavy gaze, refers to himself as a “product of the oil shock” who first discovered renewables at Texas Tech’s summer “geek camp.” The possibilities stayed with him through his days as a venture capitalist in Silicon Valley and eventually led him to Austin to head the nation’s first clean-energy incubation center. Serface made his pitch at a recent Solar San Antonio breakfast by contrasting Texas with those sun-worshipping Californians. Energy prices, he says, are “going up. They’re not going down again.” That fact makes alternative energies like solar, just starting to crack the 10-cent-per-killowatt barrier, financially viable. “The question we have to solve as an economy is, ‘Do we want to be a leader in that, or do we want to allow other countries [to outpace us] and buy this back from them?’” he asked.
  • To remain an energy leader, Texas must rapidly exploit solar. Already, we are fourth down the list when it comes not only to solar generation, but also patents issued and federal research awards. Not surprisingly, California is kicking silicon dust in our face.

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.

Oak Ridge National Laboratory: Advancing The Nuclear Enterprise Through Better Computin... - 0 views

  • In the area of nuclear energy, the Nuclear Modeling staff specializes in developing and applying computational methods and software for simulating radiation in order to support the design and safety of nuclear facilities, improve reactor core designs and nuclear fuel performance, and ensure the safety of nuclear materials, such as spent nuclear fuel. The Nuclear Modeling staff is internationally known for developing and maintaining SCALE, a comprehensive nuclear analysis software package originally developed for the Nuclear Regulatory Commission with signature capabilities in the criticality safety, reactor physics and radiation shielding areas. In recent years, ORNL has placed an emphasis on transforming its current capabilities through high-performance computing, as well as the development of new and novel computational methods
  • Scientists at the Nuclear Science and Technology Division of the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL) are merging decades of nuclear energy and safety expertise with high-performance computing to effectively address a range of nuclear energy- and security-related challenges.
  • John Wagner, Technical Integration Manager for Nuclear Modeling within ORNL's Nuclear Science and Technology Division (NSTD), says one of the goals of his organization is to integrate existing nuclear energy and nuclear national security modeling and simulation capabilities and associated expertise with high-performance computing to solve problems that were previously unthinkable or impractical in terms of the computing power required to address them.

  • "Traditionally, reactor models for radiation dose assessments have considered just the reactor core, or a small part of the core," Wagner says. "However, we're now simulating entire nuclear facilities, such as a nuclear power reactor facility with its auxiliary buildings and the ITER fusion reactor, with much greater accuracy than any other organization that we're aware of." More accurate models enable nuclear plants to be designed with more accurate safety margins and shielding requirements, which helps to improve safety and reduce costs. The technology that makes this sort of leading-edge simulation possible is a combination of ORNL's Jaguar, the world's fastest supercomputer; advanced transport methods; and a next-generation software package called Denovo

Commissioning of Nuclear Power Plants: Training and Human Resource Considerations PDF - 0 views

  •  
    A pdf, won't highlight - from the Intro - The IAEA Technical Working Group on Training and Qualification of Nuclear Power Plant Personnel (TWG-T&Q) recommended that the Agency develop a publication on experiences gained regarding commissioning training for nuclear power plant projects This recommendation was made in recognition that in many of the Member States with operating nuclear power plants it has been some years since an NPP has been commissioned, and most of the staff with experience in commissioning have since retired. Additionally, in a number of Member States serious consideration is being given to initiating new nuclear power programmes. This publication is intended to provide useful information for both of these situations.

U.S. nuclear group backs 5-year safety timeline [26Jul11] - 0 views

  • WASHINGTON (MarketWatch) -- The head of the nuclear power industry's trade group on Tuesday said U.S. plants should move within five years to implement safety measures as a result of lessons learned from Japan's nuclear crisis. Marvin Fertel, president and CEO of the Nuclear Energy Institute, said the five-year timeline put forward last week by U.S. Nuclear Regulatory Commission Chairman Gregory Jaczko was "reasonable."
  • An NRC staff task force this month recommended a host of changes to U.S. regulations based on observations of Japan's Fukuhsima Daiichi plant, which has struggled to safely shut down and control radiation after a March 11 earthquake and tsunami. In addition to saying any changes should be fully implemented within five years, Jaczko has also said the five-member commission should decide within 90 days whether it would support the staff recommendations. Fertel did not endorse Jaczko's 90-day proposal. He said acting too quickly could have unintended consequences. "We also don't want to divert operations to areas that maybe are important to safety but not as important as something else that needs to be done right now," he said.

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.
  • ...9 more annotations...
  • 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.

  • Germany's ZDF Television is here. Said 35,000 becquerels/kg [of radioactive cesium, most likely] has been found in the soil of a rice paddy planted with rice, and asked if the government does any thorough check.

Secret US-Israeli Nuke Weapons Transfers Led To Fukushima Blasts [03Oct11] - 0 views

  • Sixteen tons and what you get is a nuclear catastrophe. The explosions that rocked the Fukushima No.1 nuclear plant were more powerful than the combustion of hydrogen gas, as claimed by the Tokyo Electric Power Company. The actual cause of the blasts, according to intelligence sources in Washington, was nuclear fission of. warhead cores illegally taken from America's sole nuclear-weapons assembly facility. Evaporation in the cooling pools used for spent fuel rods led to the detonation of stored weapons-grade plutonium and uranium.   The facts about clandestine American and Israeli support for Japan's nuclear armament are being suppressed in the biggest official cover-up in recent history. The timeline of events indicates the theft from America's strategic arsenal was authorized at the highest level under a three-way deal between the Bush-Cheney team, Prime Minister Shinzo Abe and Elhud Olmert's government in Tel Aviv.
  • Tokyo's Strangelove   In early 2007, Vice President Dick Cheney flew to Tokyo with his closest aides. Newspaper editorials noted the secrecy surrounding his visit - no press conferences, no handshakes with ordinary folks and, as diplomatic cables suggest, no briefing for U.S. Embassy staffers in Tokyo.   Cheney snubbed Defense Minister Fumio Kyuma, who was shut out of confidential talks. The pretext was his criticism of President George Bush for claiming Iraq possessed weapons of mass destruction. The more immediate concern was that the defense minister might disclose bilateral secrets to the Pentagon. The Joint Chiefs of Staff were sure to oppose White House approval of Japan's nuclear program.
  • Abe has wide knowledge of esoteric technologies. His first job in the early 1980s was as a manager at Kobe Steel. One of the researchers there was astrophysicist Hideo Murai, who adapted Soviet electromagnetic technology to "cold mold" steel. Murai later became chief scientist for the Aum Shinrikyo sect, which recruited Soviet weapons technicians under the program initiated by Abe's father. After entering government service, Abe was posted to the U.S. branch of JETRO (Japan External Trade Organization). Its New York offices hosted computers used to crack databases at the Pentagon and major defense contractors to pilfer advanced technology. The hacker team was led by Tokyo University's top gamer, who had been recruited into Aum.   After the Tokyo subway gassing in 1995, Abe distanced himself from his father's Frankenstein cult with a publics-relations campaign. Fast forward a dozen years and Abe is at Camp David. After the successful talks with Bush, Abe flew to India to sell Cheney's quadrilateral pact to a Delhi skeptical about a new Cold War. Presumably, Cheney fulfilled his end of the deal. Soon thereafter Hurricane Katrina struck, wiping away the Abe visit from the public memory.

  • Since the Liberal Democratic Party selected him as prime minister in September 2006, the hawkish Abe repeatedly called for Japan to move beyond the postwar formula of a strictly defensive posture and non-nuclear principles. Advocacy of a nuclear-armed Japan arose from his family tradition. His grandfather Nobusuke Kishi nurtured the wartime atomic bomb project and, as postwar prime minister, enacted the civilian nuclear program. His father Shintaro Abe, a former foreign minister, had played the Russian card in the 1980s, sponsoring the Russo-Japan College, run by the Aum Shinrikyo sect (a front for foreign intelligence), to recruit weapons scientists from a collapsing Soviet Union.   The chief obstacle to American acceptance of a nuclear-armed Japan was the Pentagon, where Pearl Harbor and Hiroshima remain as iconic symbols justifying American military supremacy.The only feasible channel for bilateral transfers then was through the civilian-run Department of Energy (DoE), which supervises the production of nuclear weapons.
  • Camp David Go-Ahead   The deal was sealed on Abe's subsequent visit to Washington. Wary of the eavesdropping that led to Richard Nixon's fall from grace, Bush preferred the privacy afforded at Camp David. There, in a rustic lodge on April 27, Bush and Abe huddled for 45 minutes. What transpired has never been revealed, not even in vague outline.   As his Russian card suggested, Abe was shopping for enriched uranium. At 99.9 percent purity, American-made uranium and plutonium is the world's finest nuclear material. The lack of mineral contaminants means that it cannot be traced back to its origin. In contrast, material from Chinese and Russian labs can be identified by impurities introduced during the enrichment process.
  • The flow of coolant water into the storage pools ceased, quickening evaporation. Fission of the overheated cores led to blasts and mushroom-clouds. Residents in mountaintop Iitate village overlooking the seaside plant saw plumes of smoke and could "taste the metal" in their throats.   Guilty as Charged   The Tohoku earthquake and tsunami were powerful enough to damage Fukushima No.1. The natural disaster, however, was vastly amplified by two external factors: release of the Stuxnet virus, which shut down control systems in the critical 20 minutes prior to the tsunami; and presence of weapons-grade nuclear materials that devastated the nuclear facility and contaminated the entire region.   Of the three parties involved, which bears the greatest guilt? All three are guilty of mass murder, injury and destruction of property on a regional scale, and as such are liable for criminal prosecution and damages under international law and in each respective jurisdiction.
  • An unannounced reason for Cheney's visit was to promote a quadrilateral alliance in the Asia-Pacific region. The four cornerstones - the US, Japan, Australia and India - were being called on to contain and confront China and its allies North Korea and Russia.. From a Japanese perspective, this grand alliance was flawed by asymmetry: The three adversaries were nuclear powers, while the U.S. was the only one in the Quad group.   To further his own nuclear ambitions, Abe was playing the Russian card. As mentioned in a U.S. Embassy cable (dated 9/22), the Yomiuri Shimbun gave top play to this challenge to the White House : "It was learned yesterday that the government and domestic utility companies have entered final talks with Russia in order to relegate uranium enrichment for use at nuclear power facilities to Atomprom, the state-owned nuclear monopoly." If Washington refused to accept a nuclear-armed Japan, Tokyo would turn to Moscow.
  • Throughout the Pantex caper, from the data theft to smuggling operation, Bush and Cheney's point man for nuclear issues was DoE Deputy Director Clay Sell, a lawyer born in Amarillo and former aide to Panhandle district Congressman Mac Thornberry. Sell served on the Bush-Cheney transition team and became the top adviser to the President on nuclear issues. At DoE, Sell was directly in charge of the U.S. nuclear weapons complex, which includes 17 national laboratories and the Pantex plant. (Another alarm bell: Sell was also staff director for the Senate Energy subcommittee under the late Sen. Ted Stevens of Alaska, who died in a 2010 plane crash.)   An Israeli Double-Cross   The nuclear shipments to Japan required a third-party cutout for plausible deniability by the White House. Israel acted less like an agent and more like a broker in demanding additional payment from Tokyo, according to intelligence sources. Adding injury to insult, the Israelis skimmed off the newer warhead cores for their own arsenal and delivered older ones. Since deteriorated cores require enrichment, the Japanese were furious and demanded a refund, which the Israelis refused. Tokyo had no recourse since by late 2008 principals Abe had resigned the previous autumn and Bush was a lame duck.
  • The Japanese nuclear developers, under the Ministry of Economy, Trade and Industry, had no choice but to enrich the uranium cores at Fukushima No.1, a location remote enough to evade detection by nonproliferation inspectors. Hitachi and GE had developed a laser extraction process for plutonium, which requires vast amounts of electrical power. This meant one reactor had to make unscheduled runs, as was the case when the March earthquake struck.   Tokyo dealt a slap on the wrist to Tel Aviv by backing Palestinian rights at the UN. Not to be bullied, the Israeli secret service launched the Stuxnet virus against Japan's nuclear facilities.   Firewalls kept Stuxnet at bay until the Tohoku earthquake. The seismic activity felled an electricity tower behind Reactor 6. The power cut disrupted the control system, momentarily taking down the firewall. As the computer came online again, Stuxnet infiltrated to shut down the back-up generators. During the 20-minute interval between quake and tsunami, the pumps and valves at Fukushima No.1 were immobilized, exposing the turbine rooms to flood damage.
  • The Texas Job   BWXT Pantex, America's nuclear warhead facility, sprawls over 16,000 acres of the Texas Panhandle outside Amarillo. Run by the DoE and Babcock & Wilson, the site also serves as a storage facility for warheads past their expiration date. The 1989 shutdown of Rocky Flats, under community pressure in Colorado, forced the removal of those nuclear stockpiles to Pantex. Security clearances are required to enter since it is an obvious target for would-be nuclear thieves.   In June 2004, a server at the Albuquerque office of the National Nuclear Security System was hacked. Personal information and security-clearance data for 11 federal employees and 177 contractors at Pantex were lifted. NNSA did not inform Energy Secretary Samuel Bodman or his deputy Clay Sell until three months after the security breach, indicating investigators suspected an inside job.
  • The White House, specifically Bush, Cheney and their co-conspirators in the DoE, hold responsibility for ordering the illegal removal and shipment of warheads without safeguards.   The state of Israel is implicated in theft from U.S. strategic stockpiles, fraud and extortion against the Japanese government, and a computer attack against critical infrastructure with deadly consequences, tantamount to an act of war.   Prime Minister Abe and his Economy Ministry sourced weapons-grade nuclear material in violation of constitutional law and in reckless disregard of the risks of unregulated storage, enrichment and extraction. Had Abe not requested enriched uranium and plutonium in the first place, the other parties would not now be implicated. Japan, thus, bears the onus of the crime.
  • The International Criminal Court has sufficient grounds for taking up a case that involves the health of millions of people in Japan, Canada, the United States, Russia, the Koreas, Mongolia, China and possibly the entire Northern Hemisphere. The Fukushima disaster is more than an human-rights charge against a petty dictator, it is a crime against humanity on par with the indictments at the Nuremberg and Tokyo tribunals. Failure to prosecute is complicity.   If there is a silver lining to every dark cloud, it's that the Tohoku earthquake and tsunami saved the world from even greater folly by halting the drive to World War III.

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.

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.

Jiji: Footage reveals Tepco made plans to evacuate Fukushima Daiichi [19Aug12] - 0 views

  • Tokyo Electric Power Co. was considering detailed plans to pull workers from its crippled Fukushima No. 1 nuclear power plant at the outset of the crisis there in March 2011, video footage of the company’s accident response shows. The footage, released to journalists, shows teleconferences between the plant in Fukushima Prefecture, TEPCO’s head office in Tokyo and the company’s off-site crisis management center near the plant. On March 14, 2011, after hydrogen explosions at the plant’s Nos. 1 and 3 reactor buildings, officials at the TEPCO head office were frustrated with unsuccessful efforts to vent steam from the No. 2 reactor to prevent it from blowing up.
  • At the off-site center, TEPCO Managing Executive Officer Akio Komori ordered plans to be prepared to evacuate workers from the plant, which he said would be needed at some point. Later in the day, what appears to be a TEPCO staff member reported progress in making the pullout plans, including a plan to begin preparations to withdraw 1-1/2 hours before an expected meltdown at the No. 2 reactor and to evacuate 30 minutes later. The official also explained plans to move to a TEPCO building near the Fukushima No. 1 plant or the neighboring No. 2 plant. Ten buses were said to be available for evacuation, although they would not be enough to pull out all 850 plant workers at one time.

Report doesn't answer blast, radiation leak mysteries [07Dec11] - 0 views

  • Why did such massive amounts of radioactive substances escape from the crippled Fukushima No. 1 nuclear power plant? Why did explosions tear through its reactor buildings? Tokyo Electric Power Co.'s interim report on the accident at the nuclear plant shed some light on some causes of the nation's worst-ever nuclear crisis, but these and other crucial questions remain unanswered. The release of radioactive substances is believed to have peaked on the morning of March 15. As radiation spewed from the plant's reactors, residents in an extensive area--even as far as Iitatemura, Fukushima Prefecture, about 30 kilometers from the plant--were forced to evacuate.
  • The report said the air pressure in the containment vessel of the plant's No. 2 reactor dropped drastically that morning. However, TEPCO says the causal relationship between the pressure drop and the radioactive release is "unclear at this moment." It had been assumed that a blast in the pressure control chamber below the No. 2 reactor's containment vessel caused the increase in radiation leaked into the environment. Analysis of data from a seismometer and other equipment at the complex later showed this hypothesis was incorrect.
  • The report's verification of TEPCO's initial response to the nuclear accident also lacked details. After a hydrogen blast wrecked the No. 1 reactor building shortly after 3:30 p.m. on March 12--a development nobody had anticipated--TEPCO scrambled to prevent similar blasts from occurring at the other reactors.

  • The utility arranged to have a hydraulic device break open holes in the reactor buildings to release hydrogen from inside. But shortly after 11 a.m. on March 14, before the device arrived, a hydrogen blast ripped through the No. 3 reactor. The report did not specify why TEPCO failed to prevent this blast, which happened nearly two days after the first explosion. TEPCO Vice President Masao Yamazaki said: "It was difficult to obtain equipment due to bad road conditions and other problems after the [March 11] earthquake. We'll look into the matter further for the final report." There also are some loose ends regarding the injection of cooling water into the reactors.
  • Even after the huge tsunami triggered by the March 11 earthquake hit the power plant and knocked out its cooling systems, the emergency water injection system functioned for about three days at the No. 2 reactor and about 1-1/2 days at the No. 3 reactor. TEPCO had time to prepare substitute water injection methods, such as stationing fire engines at the plant. Its failure to do so eventually resulted in core meltdowns at the Nos. 1-3 reactors. The report says TEPCO's response was delayed because valves to reduce pressure in the reactors could not be operated due to a lack of electricity and "TEPCO workers had to remove batteries from staff cars to collect enough power to conduct the operation." The report did not clarify why TEPCO did not prepare more power sources while the emergency water injection system was in operation.
