NUCLEAR POWER - Resisting "Rust Belt" reactors' radioactive risks! [04Aug12] - 0 views

  • As if the closing steel mills and automobile manufacturing plants weren't bad enough, some of the oldest, most risky atomic reactors in the U.S. are located in the Midwest. Worse still, they are on the shores of the Great Lakes, putting at risk the drinking water supply for 40 million people downstream in the U.S., Canada, and a large number of Native American First Nations. Altogether, 33 atomic reactors are located on the shorelines of the Great Lakes. Two of the most infamous of these radiologically risky "Rust Belt reactors" are Entergy Nuclear's Palisades in southwest Michigan, and FirstEnergy's Davis-Besse in northwest Ohio.
  • Last month, U.S. Rep. Ed Markey (D-MA), a long-time watchdog on the nuclear industry, wrote the U.S. Nuclear Regulatory Commission (NRC) about an acidic, radioactive leak representing a "crisis in the control room at the Palisades nuclear power plant." The leakage had been ongoing for a year, and was being "contained" in glorified buckets referred to by Entergy PR spokesman Mark Savage as "catch basins." Although the leak came to light when Palisades was forced to shutdown after its rate reached more than 30 gallons per day, it had been ongoing for months at a rate of 15 gallons per day. The tritiated and borated water is leaking from a 300,000 gallon Safety Injection Refueling Water storage tank, which is safety critical for both reactor core and radiological containment cooling. Whistleblowers contacted Washington, D.C. attorney Billie Pirner Garde, who alerted Rep. Markey, who wrote NRC. The NRC Office of Investigations has launched a probe into potential Entergy wrongdoing. On July 17th, NRC issued a "Confirmatory Action Letter" which enables Palisades to keep operating into 2013, even if the leak increases to nearly 38 gallons per day!
  • Markey demanded a copy of an internal Entergy report surveying its own workers on "safety culture" at Palisades. Michigan Radio obtained a copy, which reveals "a lack of accountability at all levels," and a workforce deeply distrustful of management, fearful that they will be harassed and punished if they dare to raise safety concerns.

NRC seeks comment on DTE's proposed new Mich. reactor[28Oct11] - 0 views

  • No environmental impact found to preclude new reactor * DTE has not decided to build new reactor yet * New reactor could cost about $8.5 billion NEW YORK, Oct 28 (Reuters) - The U.S. Nuclear Regulatory Commission (NRC) said Friday it was seeking public input on a draft environmental impact statement for DTE's proposed new reactor at the Fermi nuclear power plant in Michigan. In a release, the NRC said its staff found no environmental impacts in its preliminary findings that would preclude the commission from issuing a combined license (COL) for a new reactor at Fermi. Michigan-based power company DTE submitted its new reactor application to the NRC in September 2008, requesting a license to build and operate an Economic Simplified Boiling Water Reactor (ESBWR) at Fermi next to its existing reactor about 25 miles northeast of Toledo, Ohio.

Medical Journal Article: 14,000 U.S. Deaths Tied to Fukushima Reactor Disaster Fallout ... - 0 views

  • Impact Seen As Roughly Comparable to Radiation-Related Deaths After Chernobyl; Infants Are Hardest Hit, With Continuing Research Showing Even Higher Possible Death Count
  • An estimated 14,000 excess deaths in the United States are linked to the radioactive fallout from the disaster at the Fukushima nuclear reactors in Japan, according to a major new article in the December 2011 edition of the International Journal of Health Services. This is the first peer-reviewed study published in a medical journal documenting the health hazards of Fukushima.Authors Joseph Mangano and Janette Sherman note that their estimate of 14,000 excess U.S. deaths in the 14 weeks after the Fukushima meltdowns is comparable to the 16,500 excess deaths in the 17 weeks after the Chernobyl meltdown in 1986.
  • The rise in reported deaths after Fukushima was largest among U.S. infants under age one. The 2010-2011 increase for infant deaths in the spring was 1.8 percent, compared to a decrease of 8.37 percent in the preceding 14 weeks.The IJHS article will be published Tuesday and will be available online as of 11 a.m. EST at http://www.radiation.org . Just six days after the disastrous meltdowns struck four reactors at Fukushima on March 11, scientists detected the plume of toxic fallout had arrived over American shores. Subsequent measurements by the U.S. Environmental Protection Agency (EPA) found levels of radiation in air, water, and milk hundreds of times above normal across the U.S. The highest detected levels of Iodine-131 in precipitation in the U.S. were as follows (normal is about 2 picocuries I-131 per liter of water): Boise, ID (390); Kansas City (200); Salt Lake City (190); Jacksonville, FL (150); Olympia, WA (125); and Boston, MA (92)

  • Epidemiologist Joseph Mangano, MPH MBA, said: "This study of Fukushima health hazards is the first to be published in a scientific journal. It raises concerns, and strongly suggests that health studies continue, to understand the true impact of Fukushima in Japan and around the world
  • Internist and toxicologist Janette Sherman, MD, said: "Based on our continuing research, the actual death count here may be as high as 18,000, with influenza and pneumonia, which were up five-fold in the period in question as a cause of death. Deaths are seen across all ages, but we continue to find that infants are hardest hit because their tissues are rapidly multiplying, they have undeveloped immune systems, and the doses of radioisotopes are proportionally greater than for adults."Dr. Sherman is an adjunct professor, Western Michigan University, and contributing editor of "Chernobyl - Consequences of the Catastrophe for People and the Environment" published by the NY Academy of Sciences in 2009, and author of "Chemical Exposure and Disease and Life's Delicate Balance - Causes and Prevention of Breast Cancer."The Centers for Disease Control and Prevention (CDC) issues weekly reports on numbers of deaths for 122 U.S. cities with a population over 100,000, or about 25-30 percent of the U.S. In the 14 weeks after Fukushima fallout arrived in the U.S. (March 20 to June 25), deaths reported to the CDC rose 4.46 percent from the same period in 2010, compared to just 2.34 percent in the 14 weeks prior. Estimated excess deaths during this period for the entire U.S. are about 14,000.

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.

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

  • This week, the U.S. Department of Energy (DOE) re-launched its website, Energy.gov, to provide tools to help individuals and businesses better understand how to save energy and money. You can type your zip code into the site and get hyper-local information about your city, county and state, including information on tax credits, rebates and energy saving tips.
  • The site presents DOE data visually using the open source MapBox suite of tools, and localized data and maps can be shared or embedded on any website or blog. Other data sets the DOE is mapping include alternative fuel locations and per capita energy usage. Anyone can now compare how his state’s energy usage compares with others across the country. In addition to making the data more palatable for the public, the DOE is offering open data sets for others to use.
  • Our goal is simple — to improve the delivery of public services online. We’re using government data to go local in a way that’s never been possible before. We’re connecting the work of the Energy Department with what’s happening in your backyard,” says Cammie Croft, senior advisor and director of new media and citizen engagement at the DOE. “We’re making Energy.gov relevant and accessible to consumers and small businesses in their communities.”
  • ...16 more annotations...
  • How else is the Energy Department working to bring better information about energy, renewable energies and energy technology to the public? Here are a few examples.
  • 1. Your MPG
  • The “Your MPG” feature on the site lets you upload data about your own vehicle’s fuel usage to your “cyber” garage and get a better picture of how your vehicle is doing in terms of energy consumption. The system also aggregates the personal car data from all of the site’s users anonymously so people can share their fuel economy estimates. “You can track your car’s fuel economy over time to see if your efforts to increase MPG are working,” says David Greene, research staffer at Oak Ridge National Lab. “Then you can compare your fuel data with others and see how you are doing relative to those who own the same vehicle.”
  • In the works for the site is a predictive tool you can use when you are in the market for a new or used vehicle to more accurately predict the kind of mileage any given car will give you, based on your particular driving style and conditions. The system, says Greene, reduces the +/- 7 mpg margin of error of standard EPA ratings by about 50% to give you a more accurate estimate of what your MPG will be.
  • Solar Decathlon
  • In response to the White House’s Startup America program supporting innovation and entrepreneurship, the Energy Department launched its own version — America’s Next Top Energy Innovator Challenge. The technology transfer program gives startups the chance to license Energy Department technologies developed at the 17 national laboratories across the country at an affordable price. Entrepreneurs can identify Energy Department technologies through the Energy Innovation Portal, where more than 15,000 patent and patent applications are listed along with more than 450 market summaries describing some of the technologies in layman’s terms.
  • 2. America’s Next Top Energy Innovator
  • 3. Products: Smarter Windows
  • DOE funding, along with private investments, supports a number of companies including the Michigan-based company Pleotint. Pleotint developed a specialized glass film that uses energy generated by the sun to limit the amount of heat and light going into a building or a home. The technology is called Sunlight Responsive Thermochromic (SRT™), and it involves a chemical reaction triggered by direct sunlight that lightens or darkens the window’s tint. Windows made from this glass technology are designed to change based on specific preset temperatures.
  • Another DOE-funded company, Sage ElectroChromics, created SageGlass®, electronically controlled windows that use small electric charges to switch between clear and tinted windows in response to environmental heat and light conditions. And Soladigm has an electronic tinted glass product that is currently undergoing durability testing.
  • Once a company selects the technology of interest to them, they fill out a short template to apply for an option — a precursor to an actual license of the patent — for $1,000. A company can license up to three patents on one technology from a single lab per transaction, and patent fees are deferred for two years. The program also connects entrepreneurs to venture capitalists as mentors.
  • Since 2002, the U.S. Department of Energy’s Solar Decathlon has challenged collegiate students to develop solar-powered, highly efficient houses. Student teams build modular houses on campus, dismantle them and then reassemble the structures on the National Mall. The competition has taken place biennially since 2005. Open to the public and free of charge, the next event will take place at the National Mall’s West Potomac Park in Washington, D.C. from September 23 to October 2, 2011. There are 19 teams competing this year.
  • Teams spend nearly two years planning and constructing their houses, incorporating innovative technology to compete in 10 contests. Each contest is worth 100 points to the winner in the areas of Architecture, Market Appeal, Engineering, Communications, Affordability, Comfort Zone, Hot Water, Appliances, Home Entertainment and Energy Balance. The team with the most points at the end of the competition wins.
  • Since its inception, the Solar Decathlon has seen the majority of the 15,000 participants move on to jobs related to clean energy and sustainability. The DOE’s digital strategy for the Solar Decathlon includes the use of QR codes to provide a mobile interactive experience for visitors to the event in Washington, D.C., as well as Foursquare checkin locations for the event and for each participating house. Many of the teams are already blogging leading up to the event and there are virtual tours and computer animated video walkthroughs to share the Solar Decathlon experience with a global audience. There will be TweetChats using the hashtag #SD2011 and other activities on Twitter, Facebook, Flickr and YouTube.
  • The Future
  • In terms of renewable energies, the DOE tries to stay on the cutting edge. Some of their forward-thinking projects include the Bioenergy Knowledge Discovery Framework (KDF), containing an interactive database toolkit for access to data relevant to anyone engaged with the biofuel, bioenergy and bioproduct industries. Another is an interactive database that maps the energy available from tidal streams in the United States. The database, developed by the Georgia Institute of Technology in cooperation with the Energy Department, is available online. The tidal database gives researchers a closer look at the potential of tidal energy, which is a “predictable” clean energy resource. As tides ebb and flow, transferring tidal current to turbines to become mechanical energy and then converting it to electricity. There are already a number of marine and hydrokinetic energy projects under development listed on the site.

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

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

Earless baby bunny near Fukushima Daiichi stokes fears of radiogenic mutation... - 0 views

  • A baby bunny apparently born without ears (photo at left) in the town of Namie, near the massively leaking Fukushima Daiichi nuclear power plant, has raised concerns about mutagenic effects caused by radioactivity in the environment. Naysayers abound, despite evidence of genetic mutations in animals (such as a two headed calf) and plants (including deformed flowers) in the aftermath of the Three Mile Island meltdown collected and documented by Mary Osborn; numerous scientific studies showing adverse impacts on wildlife populations in Chernobyl contaminated regions, such as on birds by Dr. Tim Mousseau of the University of South Carolina; and, further back in time, an epidemic of ewe deaths in southwest Utah immediately downwind of the Nevada Nuclear Weapons Test Site. An excellent book by John G. Fuller, "The Day We Bombed Utah," published in 1984, recounts how Mormon sheep farmers experienced unprecedented sheep and ewe deaths in the early 1950s, shortly after nuclear weapons blasts upwind in Nevada. The farmers sued the Atomic Energy Commission for damages. AEC research scientists swore, under oath, that they had no evidence that radioactivity could cause such a die off in sheep and ewes. However, over a quarter century later, it was shown by the sheep farmers and their attorney that the AEC had lied -- they had conducted experiments on sheep at the Hanford Nuclear Reservation in Washington State: they observed die offs very similar to what occurred in Utah. The same judge who had presided over the original trial heard the new evidence as well, and ruled that the AEC had perpetrated a fraud upon the court. Fuller also wrote "We Almost Lost Detroit," published in 1975, about the 1966 partial meltdown at the Fermi 1 experimental plutonium breeder reactor in Monroe, Michigan.

  • Nov. 3 — “A rare type of radioactive decay, not a renewed chain reaction, appears to have produced the radioactive xenon gas,” reports CNN.
  • According to the report, on Thursday Tepco said “it believed the gases were produced by ‘spontaneous fission’ of uranium, since the shorter-lived isotope persisted after the use of boric acid”.
  • Gary Was, a nuclear engineering professor at the University of Michigan, told CNN that ‘spontaneous’ fission occurs when an element like uranium splits on its own, though it’s an “improbable phenomenon”.

  • Professor Was noted that the detection of xenon happened less than a week after Japan began taking new gas samples from the reactors. It is highly coincidental that so soon after the sampling began an “improbable phenomenon” like ‘spontaneous’ fission would occur.

Japan Gov't on Containing Radiation: "We don't have experience in this field" - "We're ... - 0 views

  • KORIYAMA, Oct. 31 — “Japan still is struggling to figure out how to clean up the mess, exacerbating fears about health risks and fanning mistrust of the government,” reports Yumiko Ono in today’s Wall Street Journal. In fact, government policies may be increasing the spread of radioactive particles: According to the article, “Some experts say some ad hoc cleanup efforts risk spreading radiation further.” For example, Ono says schools “are temporarily storing contaminated soil in holes dug within the school compounds and lined with plastic sheets.”
  • Of this ‘storage’ method, Kimberlee Kearfott, a University of Michigan nuclear-engineering professor who has served on U.S. government panels for nuclear cleanups, says: Plastic isn’t a long-lasting seal against radioactive substances leaking. If radioactive materials get into the ground water and are concentrated there that could be worse than soil contamination because it could spread rapidly. “This type of shallow-pit burial has not been used in the U.S. since the 1960s.” “This is definitely not a good idea.” Officials at Japan’s environment ministry “concede the task is daunting,” according to the Journal article.
  • During an interview, Vice Minister Hideki Minamikawa said: “We don’t have experience in this field.” “We’re talking about such a vast area.” “Currently, there are no clear signs yet on what needs to be done to make decontamination a success.”

Earthquake readiness of U.S. nuclear power plants is unclear [25Aug11] - 0 views

  • Earthquakes are routinely measured by magnitude, or energy released. But the Nuclear Regulatory Commission (NRC)requires the nation's 104 nuclear reactors to withstand a predicted level of ground motion, or acceleration — something called g-force. What does that mean, magnitude-wise?
  • "I don't have what that translates into … unfortunately," NRC spokesman David McIntyre says. The agency released a statement Thursday to clarify its "earthquake measurements and design criteria," but it does not say what ground motion each reactor can handle. This muddiness heightens the concerns of industry critics, who have urged stricter safety rules after reactors at Japan's Fukushima Dai-ichi nuclear plant nearly melted down due to a magnitude-9.0 earthquake and tsunami on March 11.
  • A task force mandated by President Obama recommended in July that each U.S. plant be re-examined, given ongoing NRC research that shows the seismic risks for Eastern and Central U.S. nuclear power plants have increased. "The Virginia earthquake is now our local 911 call to stop delaying the implementation of stricter safety standards," Rep. Edward Markey, D-Mass., wrote in a letter this week to the NRC.

  • He noted that while the North Anna nuclear facility, near the quake's epicenter in Mineral, Va., successfully shut down Tuesday, one of its backup generators failed to work. The plant declared an "alert" — the second lowest of NRC's four emergency classifications. It regained its electricity seven hours later but is not yet back in operation. Twelve other nuclear power plants along the East Coast and upper Midwest declared an "unusual event," the lowest classification. They resumed normal operations by the end of Tuesday.

Cook and Palisades in Michigan.
  • "It's unclear how they (U.S. reactors) would stand up," says Edwin Lyman of the Union of Concerned Scientists, a non-profit group critical of nuclear energy. He says the lack of transparency about their preparedness "provides an additional smokescreen" that implies the public should just trust them. "It's not 'trust us.' It's a regulatory process," says Steve Kerekes, spokesman of the Nuclear Energy Institute, an industry group. He says each plant looks at historic seismic activity in its area, designs against that and upgrades systems as needed. Last year alone, he says, the industry spent about $7 billion on capital improvements.
  • Yet not all that money was spent on safety, and the regulatory process is "based on industry self-assessment," says Robert Alvarez, scholar at the Institute for Policy Studies and former senior adviser at the Department of Energy. "You can imagine the conflicts of interest that arise." So how prepared each nuclear plant is for an earthquake, he says, is "pretty much what the operators say it is."
  • Jim Norvelle, spokesman of Dominion Virginia Power, which operates the North Anna plant, says its two reactors were built to withstand ground motion of 0.12g to 0.18g, depending on soil composition. He says that translates into magnitudes of 5.9 to 6.2. He says that although one backup diesel generator leaked when Tuesday's quake cut off power, the plant had a spare generator and redundant safety systems to keep the reactors' radioactive cores cool.
