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.''

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.
  • 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.

  • 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.
  • 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).
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.

Scientists Radically Raise Estimates of Fukushima Fallout [25Oct11] - 0 views

  • The disaster at the Fukushima Daiichi nuclear plant in March released far more radiation than the Japanese government has claimed. So concludes a study1 that combines radioactivity data from across the globe to estimate the scale and fate of emissions from the shattered plant. The study also suggests that, contrary to government claims, pools used to store spent nuclear fuel played a significant part in the release of the long-lived environmental contaminant caesium-137, which could have been prevented by prompt action. The analysis has been posted online for open peer review by the journal Atmospheric Chemistry and Physics.
  • Andreas Stohl, an atmospheric scientist with the Norwegian Institute for Air Research in Kjeller, who led the research, believes that the analysis is the most comprehensive effort yet to understand how much radiation was released from Fukushima Daiichi. "It's a very valuable contribution," says Lars-Erik De Geer, an atmospheric modeller with the Swedish Defense Research Agency in Stockholm, who was not involved with the study. The reconstruction relies on data from dozens of radiation monitoring stations in Japan and around the world. Many are part of a global network to watch for tests of nuclear weapons that is run by the Comprehensive Nuclear-Test-Ban Treaty Organization in Vienna. The scientists added data from independent stations in Canada, Japan and Europe, and then combined those with large European and American caches of global meteorological data.
  • Stohl cautions that the resulting model is far from perfect. Measurements were scarce in the immediate aftermath of the Fukushima accident, and some monitoring posts were too contaminated by radioactivity to provide reliable data. More importantly, exactly what happened inside the reactors — a crucial part of understanding what they emitted — remains a mystery that may never be solved. "If you look at the estimates for Chernobyl, you still have a large uncertainty 25 years later," says Stohl. Nevertheless, the study provides a sweeping view of the accident. "They really took a global view and used all the data available," says De Geer.

  • Challenging numbers Japanese investigators had already developed a detailed timeline of events following the 11 March earthquake that precipitated the disaster. Hours after the quake rocked the six reactors at Fukushima Daiichi, the tsunami arrived, knocking out crucial diesel back-up generators designed to cool the reactors in an emergency. Within days, the three reactors operating at the time of the accident overheated and released hydrogen gas, leading to massive explosions. Radioactive fuel recently removed from a fourth reactor was being held in a storage pool at the time of the quake, and on 14 March the pool overheated, possibly sparking fires in the building over the next few days.
  • But accounting for the radiation that came from the plants has proved much harder than reconstructing this chain of events. The latest report from the Japanese government, published in June, says that the plant released 1.5 × 1016 bequerels of caesium-137, an isotope with a 30-year half-life that is responsible for most of the long-term contamination from the plant2. A far larger amount of xenon-133, 1.1 × 1019 Bq, was released, according to official government estimates.
  • Stohl believes that the discrepancy between the team's results and those of the Japanese government can be partly explained by the larger data set used. Japanese estimates rely primarily on data from monitoring posts inside Japan3, which never recorded the large quantities of radioactivity that blew out over the Pacific Ocean, and eventually reached North America and Europe. "Taking account of the radiation that has drifted out to the Pacific is essential for getting a real picture of the size and character of the accident," says Tomoya Yamauchi, a radiation physicist at Kobe University who has been measuring radioisotope contamination in soil around Fukushima. Click for full imageStohl adds that he is sympathetic to the Japanese teams responsible for the official estimate. "They wanted to get something out quickly," he says. The differences between the two studies may seem large, notes Yukio Hayakawa, a volcanologist at Gunma University who has also modelled the accident, but uncertainties in the models mean that the estimates are actually quite similar.
  • The new study challenges those numbers. On the basis of its reconstructions, the team claims that the accident released around 1.7 × 1019 Bq of xenon-133, greater than the estimated total radioactive release of 1.4 × 1019 Bq from Chernobyl. The fact that three reactors exploded in the Fukushima accident accounts for the huge xenon tally, says De Geer. Xenon-133 does not pose serious health risks because it is not absorbed by the body or the environment. Caesium-137 fallout, however, is a much greater concern because it will linger in the environment for decades. The new model shows that Fukushima released 3.5 × 1016 Bq caesium-137, roughly twice the official government figure, and half the release from Chernobyl. The higher number is obviously worrying, says De Geer, although ongoing ground surveys are the only way to truly establish the public-health risk.
  • The new analysis also claims that the spent fuel being stored in the unit 4 pool emitted copious quantities of caesium-137. Japanese officials have maintained that virtually no radioactivity leaked from the pool. Yet Stohl's model clearly shows that dousing the pool with water caused the plant's caesium-137 emissions to drop markedly (see 'Radiation crisis'). The finding implies that much of the fallout could have been prevented by flooding the pool earlier. The Japanese authorities continue to maintain that the spent fuel was not a significant source of contamination, because the pool itself did not seem to suffer major damage. "I think the release from unit 4 is not important," says Masamichi Chino, a scientist with the Japanese Atomic Energy Authority in Ibaraki, who helped to develop the Japanese official estimate. But De Geer says the new analysis implicating the fuel pool "looks convincing".
  • The latest analysis also presents evidence that xenon-133 began to vent from Fukushima Daiichi immediately after the quake, and before the tsunami swamped the area. This implies that even without the devastating flood, the earthquake alone was sufficient to cause damage at the plant.

    The Japanese government's report has already acknowledged that the shaking at Fukushima Daiichi exceeded the plant's design specifications. Anti-nuclear activists have long been concerned that the government has failed to adequately address geological hazards when licensing nuclear plants (see Nature 448, 392–393; 2007), and the whiff of xenon could prompt a major rethink of reactor safety assessments, says Yamauchi.

  • The model also shows that the accident could easily have had a much more devastating impact on the people of Tokyo. In the first days after the accident the wind was blowing out to sea, but on the afternoon of 14 March it turned back towards shore, bringing clouds of radioactive caesium-137 over a huge swathe of the country (see 'Radioisotope reconstruction'). Where precipitation fell, along the country's central mountain ranges and to the northwest of the plant, higher levels of radioactivity were later recorded in the soil; thankfully, the capital and other densely populated areas had dry weather. "There was a period when quite a high concentration went over Tokyo, but it didn't rain," says Stohl. "It could have been much worse."

Quake risk to reactors greater than thought - USA - [02Sept11] - 0 views

  • WASHINGTON (AP) — The risk that an earthquake would cause a severe accident at a U.S. nuclear plant is greater than previously thought, 24 times as high in one case, according to an AP analysis of preliminary government data. The nation's nuclear regulator believes a quarter of America's reactors may need modifications to make them safer.The threat came into sharp focus last week, when shaking from the largest earthquake to hit Virginia in 117 years appeared to exceed what the North Anna nuclear power plant northwest of Richmond was built to sustain.
  • The two North Anna reactors are among 27 in the eastern and central U.S. that a preliminary Nuclear Regulatory Commission review has said may need upgrades. That's because those plants are more likely to get hit with an earthquake larger than the one their design was based on. Just how many nuclear power plants are more vulnerable won't be determined until all operators recalculate their own seismic risk based on new assessments by geologists, something the agency plans to request later this year. The NRC on Thursday issued a draft of that request for public comment.
  • The NRC and the industry say reactors are safe as they are, for now. The average risk to U.S. reactors of core damage from a quake remains low, at one accident every 500 years, according to the AP analysis of NRC data.The overall risk at a typical reactor among the 27 remains very slight. If the NRC's numbers prove correct, that would mean no more than one core accident from an earthquake in about 30,000 years at the typical reactor among the 27 with increased risk.
  • ...3 more annotations...
  • The review, launched well before the East Coast quake and the Japan nuclear disaster in March, marks the first complete update to seismic risk in years for the nation's 104 existing reactors, despite research showing greater hazards
  • But emails obtained in a more than 11,000-page records request by The Associated Press show that NRC experts were worried privately this year that plants needed stronger safeguards to account for the higher risk assessments.
  • The nuclear industry says last week's quake proved reactors are robust. When the rumbling knocked out off-site power to the North Anna plant in Mineral, Va., the reactors shut down and cooled successfully, and the plant's four locomotive-sized diesel generators turned on. The quake also shifted about two dozen spent fuel containers, but Dominion Virginia Power said Thursday that all were intact.Still, based on the AP analysis of NRC data, the plant is 38 percent more likely to suffer core damage from a rare, massive earthquake than it appeared in an analysis 20 years ago.

One week delay in revealing whether quake exceeded North Anna's design basis - Seismic ... - 0 views

  • At North Anna nuclear plant, reassurances but no final data on quake impact, Washington Post by Brian Vastag, September 2, 2011:
  • [...] Yet nearly two weeks after the quake, Dominion officials were unable to say whether the quake shook the facility more than it was designed to handle. “I don’t have those numbers,” Daniel Stoddard, Dominion’s senior vice president for nuclear operations, said repeatedly. It will be another week before final analysis of the “shake plates,” which recorded ground motion at the site, is finished, he said, although a Dominion spokesman had promised that analysis by Friday. In the control room, a 1970s-era seismic detector failed to record data for a critical eight seconds when primary power went down, slowing the company’s analysis. The company has added a battery backup to the unit to prevent a recurrence. [...]

Kashiwa City's Radioactive Dirt: 276,000 Bq/Kg of Cesium [22Oct11] - 0 views

  • The highly radioactive dirt in Kashiwa City in Chiba, which measured 57.5 microsieverts/hr 30 centimeters below the surface, was not from radium after all or any other nuclides that are used in industrial or medical use (some suggested cobalt-60, for example). It was from radioactive cesium.On October 22 Kashiwa City announced the result of the analysis of three dirt samples from the location at different depth (one on the surface, two at 30 centimeter deep). The analysis was done on October 22. The unit is becquerels per kilogram:Sample A (surface dirt)Radioactive iodine: NDCesium-134: 70,200Cesium-137: 85,100Total cesium: 155,300
  • Sample B1 (30 centimeters below the surface)Radioactive iodine: NDCesium-134: 87,000Cesium-137: 105,000Total cesium: 192,000Sample B2 (30 centimeters below the surface)Radioactive iodine: NDCesium-134: 124,000Cesium-137: 152,000Total cesium: 276,000The address of the location is announced by the city as: 柏市根戸字高野台457番3地先. According to the residents, the place is a strip of open space between the residential area and the industrial area, and is used as playground by many residents, young and old.
  • On receiving the result of the analysis, the Ministry of Education and Science, who had expressed doubt that this high radiation spot in Kashiwa had anything to do with the Fukushima I Nuclear Power Plant accident, now says it cannot deny that it is the result of the accident. The ratio of cesium-134 and cesium-137 is consistent with the radio from the accident.Some speculate that someone in the city cleaned out his house and dumped the resulting radioactive sludge and dirt in this location.What I find it odd is the mismatch of the radiation on the dirt surface, 57.5 microsieverts/hour, and the density of radioactive cesium, maximum 276,000 becquerels/kilogram. The density is too low to account for the extremely high radiation. Cesium alone may not account for the high radiation, but There's no mention in the city's announcement whether it is going to test for other gamma nuclides not to mention alpha and beta.

  • Fish taken from a lake in northern Vermont had similar levels of strontium-90 and cesium-137 as fish taken from the Connecticut River near Vermont Yankee nuclear power plant in Vernon. During a Feb. 3 meeting of the House Fish, Wildlife and Water Resources Committee in the Vermont Statehouse, committee members heard from Bill Irwin, chief of radiological health for the Vermont Department of Health. "We got preliminary results from our fish sample analysis from Lake Carmi in northern Franklin County," Irwin told the Reformer on Monday. Irwin said Lake Carmine, in Enosburg Falls, is about as far away from Yankee as you can get and still be in the Green Mountain State. "The results are that cesium-137 and strontium-90 in Lake Carmi fish is in the same range as Connecticut River fish," said Irwin. "We take this as some evidence that all fish in Vermont are likely to have radioactive cesium and strontium at these levels and that, as we've hypothesized, it is from nuclear weapons fallout and the releases of Chernobyl. All of us are glad to have proof and not just conjecture." The fish taken from Lake Carmi were small-mouth bass, he said, and were taken from the lake by Vermont Fish and Wildlife fisheries personnel. Cesium was found in both edible and inedible portions of the bass, he said, while strontium was found only in inedible portions, which include bones, the head, fins and scales. "There's no danger in eating the fish," said Irwin. "Should we ever find that there are reasons to restrict diet from any sampling for any kind of radioactive or toxicological events, we would keep in mind different cultures have different diets."
  • In the same analyses, the fish had almost 500 times more potassium-40 in them than they do cesium-137, he said. Potassium-40 is a naturally occurring radioactive material that is in nearly everything and was created when the planet was formed billions of years ago, said Irwin. A fish taken from the Connecticut River in 2010 had the highest levels of strontium-90 in bone that his department has seen in any samples. "In that same sample we did find very low but measurable amounts of strontium-90 in the meat of the fish," said Irwin, which could have been a sampling or contamination error. "But we don't know that." The sampling is part of an ongoing multi-state operation to help determine what is the level of the two radioactive isotopes in fish in Vermont, New Hampshire, Massachusetts and New York. "We hope to further populate this data with fish taken from waters unaffected by nuclear power plants," said Irwin. The states are also working with the a Food and Drug Administration laboratory in Winchester, Mass., to develop sampling and analysis protocols. When more data has been assembled from around the region, Irwin said they hope to publish it in scientific journals. The results of the sampling from Lake Carmi will be posted soon on DOH's website, he said. When this year's fishing season begins, Fish and Wildlife personnel will be taking more fish for the Department of Health.

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

  • Vermont Yankee could close by March 2012 * Entergy fighting for reactor survival NEW YORK, Aug 2 (Reuters) - Vermont health regulators said on Tuesday they found a fish containing radioactive material in the Connecticut River near Entergy's (ETR.N) Vermont Yankee nuclear power plant which could be another setback for Entergy to keep it running. The state said it needs to do more testing to determine the source of the Strontium-90, which can cause bone cancer and leukemia.
  • Vermont Governor Peter Shumlin wants the 620 megawatts reactor shut in March 2012 when its original operating license was to expire. "Today's troubling news from the Vermont Department of Health is another example of Entergy Louisiana putting their shareholders' profits above the welfare of Vermonters," Shumlin said in a statement. "I am asking my Health Department to keep a close eye on test results moving forward to determine the extent of any contamination that has reached the environment."
  • New Orleans-based Entergy, the second biggest nuclear power operator in the United States, however wants to keep the reactor running for another 20 years under a new license. Entergy filed a complaint in federal court to block the state from shutting the reactor next year. Officials at Entergy were not immediately available for comment. "One finding of (Strontium-90) just above the lower limit of detection in one fish sample is notable because it is the first time Strontium-90 has been detected in the edible portion of any of our fish samples," the Vermont Department of Health said on its website. The Health Department said it did not know how the Strontium-90, which is both naturally occurring in the environment and a byproduct of nuclear power production and nuclear weapons testing, got into the fish.

  • "We cannot associate low levels of Strontium-90 in fish in the Connecticut River with Vermont Yankee-related radioactive materials without other supporting evidence," the report said. MORE ANALYSIS NEEDED The Health Department asked for additional analysis on the fish obtained on June 9, 2010 that contained the strontium-90 and also on other fish samples. These analyses will take weeks to complete, the Health Department said, noting it is working to obtain additional fish for testing much farther upstream in the Connecticut River. The Connecticut River divides Vermont and New Hampshire before running through Massachusetts and Connecticut. Vermont Yankee is located in Vernon, Vermont, near the border between Vermont, New Hampshire and Massachusetts about 110 miles northwest of Boston.
  • Strontium-90 and other human made radioactive materials come from the fairly constant release of very low quantities from medical and industrial users of radioactive materials, and from infrequent releases such as above-ground nuclear weapons testing in the 1950s, and the nuclear reactor accidents at Chernobyl in 1986 and Fukushima in 2011. Radioactive materials are nothing new for Vermont Yankee. In January 2010, Entergy said it discovered a radioactive tritium leak at the plant. The company stopped that leak in March 2010 but not before the state Senate, which was then led by now Governor Shumlin, voted to block the state from allowing the plant to run beyond March 2012.

Columbia River Area To Be Contaminated With Nuclear Waste for Millennia [10Feb10] - 0 views

  • given the fact that a new study reports that the Columbia River will be contaminated with nuclear waste from a nuclear weapons plant for thousands—yes, thousands—of years. Even though the government has already spent billions of dollars on cleanup.
  • The Oregonian reports that the Hanford Nuclear Reservation, formerly a nuclear weapons production site, sits on 586 square miles of land next to the Columbia. And it has already leaked and spilled some waste into the river, contaminating the water and surrounding environment with such fun things as strontium, cesium, tritium, and plutonium. The federal government did an analysis of the damage to determine if capping and sealing off the waste would stop more of it from getting out, and also, if more waste could be imported to the site to be buried along with the original waste.
  • The analysis also shows that the U.S. energy department's plan to import low-level and midlevel radioactive waste from other sites to Hanford after 2022 poses "completely unacceptable" risks, [assistant director of the Oregon Department of Energy Ken] Niles said. Washington is also raising concerns about importing more waste. […] Health risks from Hanford's contamination are long-term, not immediate. They're expressed in terms of cancer cases after a lifetime of drinking well water from the site, with a one in 10,000 risk considered high. But many of the contaminant levels at the site exceed health benchmarks by wide margins.

Battling for nuclear energy by exposing opposition motives [19Jul11] - 0 views

  • In the money-driven battle over our future energy supply choices, the people who fight nuclear energy have imagination on their side. They can, and often do, invent numerous scary tales about what might happen without the need to actually prove anything.
  • One of the most powerful weapons in their arsenal is the embedded fantasy that a nuclear reactor accident can lead to catastrophic consequences that cannot be accepted. This myth is doubly hard to dislodge because a large fraction of the nuclear energy professionals have been trained to believe it. When you want to train large numbers of slightly above average people to do their job with great care and attention to detail, it can be useful to exaggerate the potential consequences of a failure to perform. It is also a difficult myth to dislodge because the explanation of why it is impossible requires careful and often lengthy explanations of occasionally complex concepts.
  • The bottom lines of both Chernobyl and Fukushima tell me that the very worst that can realistically happen to nuclear fission reactors results in acceptable physical consequences when compared to the risk of insufficient power or the risk of using any other reliable source of power. The most negative consequences of both accidents resulted from the way that government leaders responded, both during the crisis stage and during the subsequent recoveries.

  • Instead of trying to explain the basis for those statements more fully, I’ll try to encourage people to consider the motives of people on various sides of the discussion. I also want to encourage nuclear energy supporters to look beyond the financial implications to the broader implications of a less reliable and dirtier electrical power system. When the focus is just on the finances, the opposition has an advantage – the potential gains from opposing nuclear energy often are concentrated in the hands of extremely interested parties while the costs are distributed widely enough to be less visible. That imbalance often leads to great passion in the opposition and too much apathy among the supporters. Over at Idaho Samizdat, Dan Yurman has written about the epic battle of political titans who are on opposing sides of the controversy regarding the relicensing and continued operation of the Indian Point Nuclear Power Station. Dan pointed out that there is a large sum of money at stake, but he put it in a way that does not sound too terrible to many people because it spreads out the pain.
  • In round numbers, if Indian Point is closed, wholesale electricity prices could rise by 12%.
  • A recent study quoted in a New York Times article put the initial additional cost of electricity without Indian Point at about $1.5 billion per year, which is a substantial sum of money if concentrated into the hands of a few thousand victors who tap the monthly bills of a few million people. Here is a comment that I added to Dan’s post:Dan – thank you for pointing out that the battle is not really a partisan one determined by political party affiliation. By my analysis, the real issue is the desire of natural gas suppliers to sell more gas at ever higher prices driven by a shift in the balance between supply and demand.
  • They never quite explain what is going to happen as we get closer and closer to the day when even fracking will not squeeze any more hydrocarbons out of the drying sponge that is the readily accessible part of the earth’s crust.The often touted “100 – year” supply of natural gas in the US has a lot of optimistic assumptions built in. First of all, it is only rounded up to 100 years – 2170 trillion cubic feet at the end of 2010 divided by 23 trillion cubic feet per year leaves just 94 years.
  • Secondly, the 2170 number provided by the Potential Gas Committee report includes all proven, probable, possible and speculative resources, without any analysis of the cost of extraction or moving them to a market. Many of the basins counted have no current pipelines and many of the basins are not large enough for economic recovery of the investment to build the infrastructure without far higher prices.Finally, all bets are off with regard to longevity if we increase the rate of burning up the precious raw materia
  • BTW – In case your readers are interested in the motives of a group like Riverkeepers, founded and led by Robert F. Kennedy, Jr., here is a link to a video clip of him explaining his support for natural gas.http://atomicinsights.com/2010/11/power-politics-rfk-jr-explains-how-pressure-from-activists-to-enforce-restrictions-on-coal-benefits-natural-gas.html
  • The organized opposition to the intelligent use of nuclear energy has often painted support for the technology as coming from faceless, money-hungry corporations. That caricature of the support purposely ignores the fact that there are large numbers of intelligent, well educated, responsible, and caring people who know a great deal about the technology and believe that it is the best available solution for many intransigent problems. There are efforts underway today, like the Nuclear Literacy Project and Go Nuclear, that are focused on showcasing the admirable people who like nuclear energy and want it to grow rapidly to serve society’s never ended thirst for reliable power at an affordable price with acceptable environmental impact.
  • The exaggerated, fanciful accident scenarios painted by the opposition are challenging to disprove.
  • I just read an excellent post on Yes Vermont Yankee about a coming decision that might help to illuminate the risk to society of continuing to let greedy antinuclear activists and their political friends dominate the discussion. According to Meredith’s post, Entergy must make a decision within just a week or so about whether or not to refuel Vermont Yankee in October. Since the sitting governor is dead set against the plant operating past its current license expiration in the summer of 2012, the $100 million dollar expense of refueling would only result in about 6 months of operation instead of the usual 18 months.Meredith has a novel solution to the dilemma – conserve the fuel currently in the plant by immediately cutting the power output to 25%.

Quake's jolts were double nuke plant's design - North Anna Plant, USA [08Sep11] - 5 views

shared by D'coda Dcoda on 08 Sep 11 - No Cached
  • The magnitude-5.8 earthquake last month in Virginia caused about twice as much ground shaking as a nearby nuclear power plant was designed to withstand, according to a preliminary federal analysis.
  • Parts of the North Anna Power Station in Mineral, Va., 11 miles from its epicenter, endured jolts equal to 26% of the force of gravity (0.26g) from some of the higher-frequency vibrations unleashed by the quake, said Scott Burnell, spokesman of the Nuclear Regulatory Commission.
  • An NRC document says the reactors' containment structure was built to withstand 12% of the force of gravity (0.12g.) Dominion, the power company that operates the plant, says parts of the plant can handle up to 0.18g.STORY: Quake readiness of nuclear power plants unclear
  • ...4 more annotations...
  • "It's the things inside the buildings that may have been shaken more than the design called for," Burnell said, adding that the buildings themselves appear to have been less affected. He said the analysis is based on a seismograph reading taken about 30 miles away by the U.S. Geological Survey.
  • Whatever the final numbers on shaking or ground motion, the plant withstood the jolts, Burnell said, indicating there's a "great deal" of safety margin."That margin was certainly enough for North Anna this time," he said.
  • "Maybe you shouldn't rely on the margin," said Edwin Lyman at the Union of Concerned Scientists, an organization critical of nuclear energy. "The jury is still out," he said, on whether the plant was adequately designed.The two reactors at the North Anna plant, which began operation in 1978 and 1980, have remained closed since the Aug. 23 quake. They automatically shut down after losing off-site power. Backup diesel generators kept their cores cool until electricity was restored several hours later.
  • Dan Stoddard, Dominion's senior vice president of operations, said Friday that initial readings from the facility's scratch plates and other monitors indicate its shaking during the quake exceeded its design, but he declined to give numbers. Dominion officials plan to brief the NRC today on those findings.

University of Tokyo and Japan Atomic Energy Agency Support POTRBLOG Analysis On Fukushi... - 0 views

  • On May 4th 2011 the Potrblog team described the Fukushima 3 explosion and spent fuel rod ejections as the result of spent fuel cooling water becoming supersaturated with hydrogen
  • "It is also likely that the water in the fuel cooling pond was supersaturated with hydrogen. When the explosion occurred, the hydrogen in solution in the cooling pond water would have frothed up, burned, and deflagrated, sending the fuel rods out of the top of the holding pond. Visualize a bottle of Coke dropping; the resultant the carbon dioxide coming out of solution and shooting out of the end; now instead of carbon dioxide picture it as burning hydrogen shooting out"
  • Empirical lab research by the University of Tokyo and the Japanese Atomic Energy Agency now confirms the generation of hydrogen in such fuel pools. They attribute the explosion in Fukushima 4 to hydrogen generated in fuel pools. The POTRBLOG team suspects that unlike Fukushima 3, the Fukushima 4 explosion did not manifest a large BLACK mushroom cloud because the Fukushima 4 explosion triggered before the fuel pools could become supersaturated with Hydrogen and Oxygen.This early triggering, as compared to Fukushima 3, would have limited damage to the roof line of the Fukushima 4 building. For POTRBLOG's full analysis on the Unit 3 explosion see:Was the Fukushima Daiichi #3 EXPLOSION a detonation or deflagration?
