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.''

Senate Appropriators on Nuclear Energy [16Sep11] - 0 views

shared by D'coda Dcoda on 09 Oct 11 - No Cached
  • The Senate Energy and Water Development Appropriations Subcommittee included extensive language in their FY 2012 committee report about nuclear energy.  They wrote of being “extremely concerned that the United States continues to accumulate spent fuel from nuclear reactors without a comprehensive plan to collect the fuel or dispose of it safely, and as a result faces a $15,400,000,000 liability by 2020,” called for the development of “consolidated regional storage facilities,” and mandated research on dry cask storage, advanced fuel cycle options, and disposal in geological media.  The appropriators provided no funding for the Next Generation Nuclear Plant program or Light Water Reactor Small Modular Reactor Licensing Technical Support.  In a separate section, they direct the Nuclear Regulatory Commission to contract with the National Academy of Sciences for a study on the lessons learned from the Fukushima nuclear disaster, and discuss beyond design-basis events and mitigating impacts of earthquakes. Language from the committee report 112-75 follows, with page number references to the pdf version of this document.
  • Nuclear Energy The FY 2011 appropriation was $732.1 million The FY 2012 administration request was $754.0 million The FY 2012 House-passed bill provides $733.6 million, an increase of $1.5 million or 0.2 percent from the current budget. The Senate Appropriations Committee bill provides $583.8 million, a decline of $148.3 million or 20.3 percent.
  • “The Committee has provided more than $500,000,000 in prior years toward the Next Generation Nuclear Plant [NGNP] program.  Although the program has experienced some successes, particularly in the advanced research and development of TRISO [tristructural-isotropic] fuel, the Committee is frustrated with the lack of progress and failure to resolve the upfront cost-share issue to allocate the risk between industry and the Federal Government. Although the Committee has provided sufficient time for these issues to be resolved, the program has stalled. Recognizing funding constraints, the Committee cannot support continuing the program in its current form. The Committee provides no funding to continue the existing NGNP program, but rather allows the Department to continue high-value, priority research and development activities for high-temperature reactors, in cooperation with industry, that were included in the NGNP program.”

  • “While the Nuclear Regulatory Commission has found that spent nuclear fuel can be stored safely for at least 60 years in wet or dry cask storage beyond the licensed life of the reactor, the Committee has significant questions on this matter and is extremely concerned that the United States continues to accumulate spent fuel from nuclear reactors without a comprehensive plan to collect the fuel or dispose of it safely, and as a result faces a $15,400,000,000 liability by 2020. The Committee approved funding in prior years for the Blue Ribbon Commission on America’s Nuclear Future [BRC], which was charged with examining our Nation’s policies for managing the back end of the nuclear fuel cycle and recommending a new plan. The BRC issued a draft report in July 2011 with recommendations, which is expected to be finalized in January 2012. The Committee directs prior existing funding, contingent on the renewal of its charter, to the BRC to develop a comprehensive revision to Federal statutes based on its recommendations, to submit to Congress for its consideration.
  • “The Committee directs the Department to develop and prepare to implement a strategy for the management of spent nuclear fuel and other nuclear waste within 3 months of publication of the final report of the Blue Ribbon Commission on America’s Nuclear Future.  The strategy shall reduce long-term Federal liability associated with the Department’s failure to pick up spent fuel from commercial nuclear reactors, and it should propose to store waste in a safe and responsible manner. The Committee notes that a sound Federal strategy will likely require one or more consolidated storage facilities with adequate capacity to be sited, licensed, and constructed in multiple regions, independent of the schedule for opening a repository. The Committee directs that the Department’s strategy include a plan to develop consolidated regional storage facilities in cooperation with host communities, as necessary, and propose any amendments to Federal statute necessary to implement the strategy.
  • “Although successfully disposing of spent nuclear fuel permanently is a long-term effort and will require statutory changes, the Committee supports taking near- and mid-term steps that can begin without new legislation and which provide value regardless of the ultimate policy the United States adopts. The Committee therefore includes funding for several of these steps in the Nuclear Energy Research and Development account, including the assessment of dry casks to establish a scientific basis for licensing; continued work on advanced fuel cycle options; research to assess disposal in different geological media; and the development of enhanced fuels and materials that are more resistant to damage in reactors or spent fuel pools.
  • (Page 80) “The events at the Fukushima-Daiichi facilities in Japan have resulted in a reexamination of our Nation’s policies regarding the safety of commercial reactors and the storage of spent nuclear fuel.  These efforts have been supported by appropriations in this bill, and the Committee provides funding for continuation and expansion of these activities.
  • The report also contains extensive language regarding Nuclear Energy Research and Development: “Use of Prior Existing Balances. - If the Secretary renews the charter of the Blue Ribbon Commission, the Department is directed to use $2,500,000 of prior existing balances appropriated to the Office of Civilian Radioactive Waste Management to develop a comprehensive revision to Federal statutes based on its recommendations.  The recommendation should be provided to Congress not later than March 30, 2012 for consideration.
  • “Nuclear Energy Enabling Technologies. - The Committee recommends $68,880,000 for Nuclear Energy Enabling Technologies, including $24,300,000 for the Energy Innovation Hub for Modeling and Simulation, $14,580,000 for the National Science User Facility at Idaho National Laboratory, and $30,000,000 for Crosscutting research.  The Committee does not recommend any funding for Transformative research. The Committee recommends that the Department focus the Energy Innovation Hub on the aspects of its mission that improve nuclear powerplant safety.
  • Light Water Reactor Small Modular Reactor Licensing Technical Support. - The Committee provides no funding for Light Water Reactor Small Modular Reactor Licensing Technical Support. “Reactor Concepts Research, Development, and Demonstration. - The Committee provides $31,870,000 for Reactor Concepts Research, Development and Demonstration. Of this funding, $21,870,000 is for Advanced Reactor Concepts activities. The Committee does not include funding for the Next Generation Nuclear Plant Demonstration project. The Department may, within available funding, continue high-value, priority research and development activities for high-temperature reactor concepts, in cooperation with industry, that were conducted as part of the NGNP program.  The remaining funds, $10,000,000, are for research and development of the current fleet of operating reactors to determine how long they can safely operate.
  • “Fuel Cycle Research and Development. - The Committee recommends $187,917,000 for Fuel Cycle Research and Development.  Within available funds, the Committee provides $10,000,000 for the Department to expand the existing modeling and simulation capabilities at the national laboratories to assess issues related to the aging and safety of storing spent nuclear fuel in fuel pools and dry storage casks. The Committee includes $60,000,000 for Used Nuclear Fuel Disposition, and directs the Department to focus research and development activities on the following priorities: $10,000,000 for development and licensing of standardized transportation, aging, and disposition canisters and casks; $3,000,000 for development of models for potential partnerships to manage spent nuclear fuel and high level waste; and $7,000,000 for characterization of potential geologic repository media.
  • “The Committee provides funding for evaluation of standardized transportation, aging and disposition cask and canister design, cost, and safety characteristics, in order to enable the Department to determine those that should be used if the Federal Government begins transporting fuel from reactor sites, as it is legally obligated to do, and consolidating fuel. The Committee notes that the Blue Ribbon Commission on America’s Nuclear Future has, in its draft report, recommended the creation of consolidated interim storage facilities, for which the Federal Government will need casks and canisters to transport and store spent fuel.

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.
  • "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.
  • 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.
  • 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.
  • 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.

Arnie Gundersen has inflated his resume, yet frequently claims that Entergy cannot be t... - 0 views

  • Arnie Gundersen, who lives here in Burlington, is Chief Engineer of Fairewinds Associates is a well-known authority on the subject, someone who has figured prominently in recent accounts of Vermont Yankee circumstances.
  • Mr. Gundersen, who has almost four decades experience in the nuclear power industry, earned his Bachelors and Masters in Nuclear Engineering from RPI. He was a licensed reactor operator and put in twenty years in the industry. He’s led teams of engineers dealing with nuclear reactors at 70 nuclear plants around the nation. He was appointed by now Governor Peter Schumlin to the Vermont Yankee Oversight Panel in 2008 and it’s his expertise that qualifies him as an expert witness on various aspects of Vermont Yankee, including plant safety, its decommissioning fund, and the suitability of the plant being extended past 2012.
  • There are several exaggerations in that brief statement. Because he has been an expert witness, Mr. Gundersen has been required to provide an accurate resume to public bodies; you can find one such document at the end of the testimony that he provided in March 2006 to oppose the Public Service of Vermont’s decision to allow Entergy to increase the power output from Vermont Yankee.
  • ...11 more annotations...
  • A careful reading of that resume reveals only one mention of any kind of license to operate a reactor. In the section of his resume headed Rensselaer Polytechnic Institute (RPI) 1971 to 1972, there is the following statement: “Critical Facility Reactor Operator, Instructor. Licensed AEC reactor operator instructing students and utility reactor operators in start-up through full power operation of a reactor.” Here is a quote about that critical facility from a contact who attended RPI at the same time as Gundersen did.
  • It operated at no pressure, room temperature, licensed to 100W, highly enriched U, open tank of water.
  • A second exaggeration comes in the statement that Gundersen has “almost four decades experience in the nuclear power industry.” His resume shows that he graduated from school in 1972 and that he stopped working for Nuclear Energy Services in 1990. From that point on, his full time employment was as a math and science teacher at a series of private schools. His resume lists several items under the heading of Nuclear Consulting 1990 – Present, but it would be interesting to hear the opinion of nuclear professionals about how those activities count as experience in the nuclear industry.
  • An Atomic Insights reader who is personally familiar with the work that Gundersen did at Northeast Utilities during the period from 1972-1976 read the posted resume and shared the following comment with me using the polite and understated language that is common among engineering professionals.
  • I think he exaggerated his responsibilities for projects at NU, 1972-6.
  • I spoke to that contact at length a few days ago, he told me that Gundersen was assigned to the licensing group and did not have any real design engineering responsibilities while at NU.
  • In 2008, he applied to become a member of the Diablo Canyon Safety Committee. On that application, he made the following statement about his experience:
  • Since 1970 Arnold Gundersen has been an expert witness in nuclear litigations at the Federal and State hearings such as Three Mile Island, US NRC ASLB, Vermont State Public Service Board, Western Atlas Nuclear Litigation, U.S. Senate Nuclear Safety Hearings, Peach Bottom Nuclear Power Plant Litigation, &c. He has also testified at the Czech Senate on nuclear matters.
  • I went back and checked the resume linked to above. According to that resume, Mr. Gundersen earned his BS in Nuclear Engineering from RPI in 1971, so he was still an undergraduate student in 1970. That leads me to the conclusion that either there was a judge somewhere who has rather low standards for expertise for his witnesses, or that Mr. Gundersen needs someone to give him a calendar for Christmas.When noticing that, I also reread the first job listed on his resume. Here is how that job was described:
  • “Public Service Electric and Gas (PSE&G) – 1970Assistant Engineer:Performed Shielding design of radwaste and auxiliary buildings for Newbold Island Units 1 & 2, including development of computer codes.”
  • The date listed for that job was before his graduation date. My guess is that it was a summer internship since Newbold Island, NJ is 218 miles from Troy, NY, the home of RPI. That would be a long commute if the job was done during the school year

Regulator Approves Southern's Reactors as Chairman Dissents [10Feb12] - 0 views

  • The U.S. Nuclear Regulatory Commission approved Southern Co.’s (SO) application for the first licenses to build reactors in more than 30 years, with the chairman’s dissenting vote sparking new controversy over whether safety upgrades are needed after Japan’s 2011 disaster.
  • The split vote mars the start of a new atomic era as Southern builds the first U.S. nuclear reactor from a standardized design that promises to speed construction and reduce risks of runaway costs that plagued nuclear development during the 1970s and 1980s. “I simply cannot ignore what happened at Fukushima,” Chairman Gregory Jaczko said in a statement after the 4-1 vote today at NRC headquarters in Rockville, Maryland.
  • Jaczko said in an interview he couldn’t support the licenses without a binding agreement from Atlanta-based Southern and its partners that the new reactors would be able to handle a power failure, earthquake, flooding and other hazards that contributed to explosions and meltdowns at the stricken Japanese station. The licensing process “is a little bit like buying a house,” where home inspectors identify things that need to be fixed, Jaczko said. “Once you close on your house, which would be like issuing a license, you own those problems.”
  • ...2 more annotations...
  • Southern Co. and industry officials said Jaczko’s concerns were appropriate for the old generation of reactors operated at Fukushima Dai-Ichi and in the U.S., but were overblown for the atomic generators under construction at Vogtle, about 26 miles (42 kilometers) southeast of Augusta, Georgia. “Greg Jaczko, I think, was making a statement that it is a new day and we’re clearly prioritizing safety,” said Michaele “Mikey” Brady Raap, a nuclear engineer and board member of the American Nuclear Society, an organization of nuclear engineers and scientists. “It was kind of a strange way to do it.”
  • Southern’s plans for Vogtle and the new reactors themselves were vetted by the commission over a five-and-a-half-year process, Thomas Fanning, Southern’s chairman and chief executive officer, said during an interview today.

Despite Fukushima demonstration, NRC task force ignores warning on dangerous ... - 0 views

  • The Nuclear Regulatory Commission’s (NRC) “Near-Term Task Force Review of Insights from the Fukushima Dai-ichi Accident” publicly released its 92-page well intentioned near-term review on the implications of the Fukushima Daiichi nuclear disaster for US reactors on July 13, 2011.  The federal agency proposes to improve its “patchwork of regulatory requirements” developed “piece by piece over the decades.” Beyond Nuclear remains concerned that many critical reactor safety areas are still dominated by industry “voluntary initiatives” where non-compliance continues to elude federal enforcement and  Capitol Hill pro-nuclear champions announced their resistance to any costly safety improvements
  • Of most concern, the NRC is still ignoring warnings as did its predecessor, the Atomic Energy Commission,  in 1972 from their senior safety officer, Dr. Steven Hanuaer to “discourage all further use” in the US of the Fukushima-style General Electric Mark I boiling water reactor. The federal regulators instead issued three more construction permits and eventually 16 more operating licenses in the 1970s for this same dangerous design. There are now 23 Fukushima-style reactors operating in the United States as part of a total of 32 Mark I’s worldwide---counting the smoldering radioactive rubble at Fukushima.   The NRC task force report does not fundamentally address the most critical issue coming out of the Fukushima catastrophe, namely, the design vulnerability of all Mark I containment structures to catastrophic failure during a severe accident
  • The NRC report further ignores that these same Mark I reactors, like Vermont Yankee and Oyster Creek, are not currently in compliance with their operating licenses that were originally required to have a reliable "leak tight" containment structure. If the NRC were looking for the most significant and meaningful safety upgrade to the US reactors directly impacted by the Fukushima disaster they would require that all Mark I reactor operators restore containment integrity to the original licensed leak tight condition. Or order that they be shut them down, permanently.  All of the Mark I reactors voluntarily installed retrofits to vent all a substandard and undersized containment to save it from rupturing during a severe accident. The same experimental vent was installed at Fukushima in 1991. The same experimental fix failed on three containments buildings to prevent the uncontrolled releases of radioactivity to the air and water that are still occurring now four months after the accident.
  • ...2 more annotations...
  • Instead, in order to keep these dangerous reactors operational, many now with twenty year license extensions, the NRC task force is recommending that rather than the industry volunteering a dubious containment vent system, the NRC should order the nuclear industry to take another try at an experimental venting fix which fundamentally compromises their own defense in depth philosophy.
  • the same day that the NRC  publicly released its report in the USA, Japanese Prime Minister Naoto Kan announced that the implications of Fukushima for nuclear power in Japan meant that “’We will aim to bring about a society that can exist without nuclear power,’ he said.” Perhaps, now too late for a society to live without the threat of increasing radioactivity levels.

French company wins US license to build, operate Idaho uranium enrichment plant [13Oct11] - 0 views

  • France’s state-owned nuclear reactor builder on Wednesday won a U.S. license to build and operate a gas centrifuge uranium enrichment plant in Idaho, a key step in the company’s plans to expand production of nuclear fuel in the United States. The federal Nuclear Regulatory Commission’s license for the $3 billion Eagle Rock Enrichment Facility authorizes Areva SA to enrich uranium for use in the manufacture of nuclear fuel for commercial power reactors. The project could supply 104 U.S. nuclear power plants, company spokesman Jarret Adams said
  • Nuclear power opponents who have been fighting the enrichment plant since Areva won tax concessions from the 2008 Idaho Legislature contend there’s already plenty of nuclear fuel in the U.S. The Snake River Alliance also points to Germany’s and Switzerland’s separate decisions to phase out nuclear energy by 2022 following the meltdown in Japan earlier this year.
  • “There is not, never has been and never will be a need for this dangerous uranium enrichment factory,” alliance executive director Liz Woodruff said. “There is an ample supply of enriched uranium worldwide today and the government has seriously miscalculated the need for more of it.” The NRC said it will inspect Areva’s site during construction.

U.S. Industry Taking Steps to Learn Lessons from Japan, Enhance Safety at America's Nuc... - 0 views

  • The nuclear energy industry will continue to work with the Nuclear Regulatory Commission as it considers forthcoming recommendations of an agency task force on new procedures and regulations in light of the accident at Fukushima Daiichi.  We have undertaken significant work in the past 90 days to examine our facilities and take the steps necessary to enhance safety.  We will continue to work with the Nuclear Regulatory Commission to understand any potential gaps in safety and fill those gaps. Prompted by the Fukushima accident, the NRC staff has been developing recommendations to enhance safety at America’s reactors. The task force is expected to release its report to the NRC commissioners within the next week. In their interim reports, NRC officials have emphasized that issues identified during the recent inspections will not impede the facilities’ ability to maintain safety even in the face of extreme events.
  • These NRC’s inspections complement industry efforts begun within days of the Fukushima Daiichi accident. Each of the nation’s 104 nuclear energy facilities has been subjected to a comprehensive verification of preparedness to maintain safety during a severe event, regardless of the cause. As a result of these self-inspections, facility operators have made immediate enhancements or developed plans to enhance safety. The vast majority of the items identified by the industry are enhancements to safety measures already in place.
  • The NRC has also made clear that issues identified during its post-Fukushima inspections at each plant do not undermine any facility’s ability to respond to extreme events. This conclusion is based upon exemplary levels of safe operation and the multiple layers of protection that exist at each nuclear energy facility in the country.   Moreover, in its annual reports to Congress, the NRC has listed only one “abnormal occurrence” over the past decade—an incident nine years ago that did not result in the release of radiation. Over the last 10 years, the NRC has not identified any negative trends in safety at America’s nuclear facilities. In the wake of the tragedy in Japan, Americans are concerned about whether U.S. reactors face the same risks.  The fact is, American nuclear facilities are subject to more regulatory scrutiny and requirements than in any other country.  American nuclear energy facilities are equipped and employees are trained to manage severe events. Since the terrorist attacks of Sept. 11, 2001, the industry has made significant improvements in physical structures and emergency response capabilities.

  • Commitment to Continuous Learning, Safety
  • The U.S. industry—through its commitment to continuous learning and relentless pursuit of excellence in safe operations—has taken significant action to ensure that American reactors are operated safety and securely. This includes actions in the following areas: Command and control: key operational and response decisions remain with shift supervisor—Decision-making remains on site with licensed operators. Reactor operators drill on accident scenarios several times each year and are prepared to respond to a wide range of potential severe events.
  • Operator licensing and training—U.S. reactor operators are licensed by the NRC and must re-qualify for their license every two years. U.S. reactor operators spend one week out of six in simulator training, which is more continuous training than pilots and doctors. Safety culture—The industry’s safety culture is transparent and encourages and facilitates the reporting of problems or concerns by employees through several channels. A commitment to safety culture is evidenced by employees who embrace continuous learning and maintain a questioning attitude regarding safety. This attitude gives rise to tools like corrective actions programs.
  • Independent regulator that includes resident inspectors—The NRC is an independent agency whose sole mission is protection of public health and safety. NRC inspectors located at each of America’s nuclear energy facilities have unfettered access to workers and data as part of their daily inspections. Creation of the Institute of Nuclear Power Operations—INPO was formed by the industry after the Three Mile Island accident to drive industry toward operational excellence and above and beyond NRC requirements. Post 9/11 security contingency measures—The NRC and industry took several actions after 9/11 to enhance security at America’s nuclear energy facilities. These features also would help mitigate extreme events, such as large fires or explosions.

Nuclear energy ~ Think again [22Oct11] - 0 views

  • It is fashionable among green groups and others who have utopian visions of a low tech post industrial society to say that nuclear energy is finished as a result of the Fukushima crisis. This is dead wrong. Charles D. Ferguson, President of the Federation of American Scientists, has an important essay in Foreign Policy Magazine on the subject. In an article titled, "Think Again: Nuclear Power," he writes that while Japan has "melted down, that doesn't mean the end of the atomic age."His point is that the fashionable approach to the nuclear fuel cycle is sometimes wrong.Also, there is other positive news about nuclear energy. The NRC is making headway with the final design certification of the Westinghouse AP1000. South Africa will try again to get financing and build new nuclear reactors instead of more coal plants.
  • Here's a quick summary of Ferguson's essay.First, Fukushima did not kill the nuclear renaissance. Germany already had a significant anti-nuclear political constituency well before March 11, 2011. Fukushima simply accelerated a process that was already underway. Meanwhile, China, India, and South Korea are moving ahead with their plans to rely on nuclear energy.Second, nuclear energy is not "an accident waiting to happen." The accidents which have happened are mostly the result of issues with organizational culture, and not technology failures.
  • Third, the expense of building nuclear power plants is offset by the low cost of running them. Once you factor in the benefits of stopping carbon emissions and the issue of climate change, nuclear energy looks like a bargain. While nuclear energy has been good for highly industrialized countries, it doesn't have nearly the same potential in the developing world for two reasons – cost and lack of robust electrical grids. Ferguson doesn't address small modular reactors which could find a niche in these markets.Fourth, commercial nuclear development does not necessarily lead to bomb making. Most of the 30 or so countries that use nuclear power have not built their own enrichment plants nor reprocessing centers.

  • Firth, management of radioactive waste and spent fuel are solvable problems. Dry cask storage works and deep geologic repositories are feasible once you get the politics right.Sixth, windmills will not replace reactors nor will solar nor anytime soon. These are intermittent and niche technologies which require massive government subsidies to get their electricity to market. Smart grids will improve the use of these technologies, but claimed improvements in energy storage technologies contain some starry eyed projections.The FAS describes itself as being focused on national and international security issues connected to applied science and technology. 
  • South Africa new buildThe South African government, which tried to offer a tender for 12 new nuclear reactors in 2008, but failed to arrange the financing for them, is making a second attempt. Energy Minister Dipuo Peters told financial wire services Oct 19 a tender for 9.6 GWe is under review by the government.The reactors would be built over a period of two decades. The bid process could begin as early as winter 2012.
  • The first U.S. utility to break ground for twin AP1000s is Southern at its Vogtle site in Georgia. Southern says it expects a combined construction and operating license sometime in the first months of 2012. At that time it will also ink the final term sheet of its $8.3 billion loan guarantee with the Department of Energy.Other utilities which plan to build twin AP1000s include Scana (2 at V.C. Summer site in South Carolina, Florida Power & Light at Turkey Point and Progress at Levy County. Both sites are in Florida.
  • NRC progress with AP1000The Nuclear Regulatory Commission's technical staff has recommended to the full commission that it approve final design certification of the Westinghouse AP1000. According to agency officials, the commission will vote on the matter by the end of the year. Eight new reactors in the southeast have referenced the AP1000 design. Construction of four units is already underway in China.The NRC rejected a petition by anti-nuclear groups to stop all new licensing until safety improvements related to the Fukushima crisis are issued as regulatory requirements. The commission said that the Part 52 licensing process allows for new safety measures to be added to licenses as the commission approves them.
  • The value at $4,000/kw could be in the range of $38 billion for the reactors, but as much as three times that amount in total for turbines, upgrades to the grid, including lines and substations, first fuel loads, and spent fuel management.A critical issue remains which is how the government will finance the new build. The country has suffered through a series of power crisis because in prior years the government failed to raise rates or diverted money from Eskom, the state owned utility, to social welfare purposes. As a result, the country's overall GDP suffered as manufacturing plants and mines had to close periodically or reduce operations due to problems with electricity supply.Since then the government has imposed rate increases, but faces some political opposition because of chronically high unemployment officially measured at 25% of the workforce. New coal plants are being built along with wind and solar plants.An interesting note is that China's Guangdong Nuclear Power Group has indicated interest in providing the financing in return for the right to build and operating the plants. Other bidders include the major developed country vendors.

The Nuclear Reactors That Power Knowledge Not Light Bulbs [09Nov11] - 0 views

  • In addition to regulating commercial nuclear power reactors that generate 20 percent of the nation’s electricity, the NRC also regulates much smaller reactors used for research, training and development. These “research and test reactors,” often called RTRs or non-power reactors, contribute to almost every field of science including physics, chemistry, biology, medicine, geology, archeology, and environmental sciences. Most are located at universities or colleges. (The NRC does not regulate research reactors run by the Department of Energy.) The most common use for these small reactors is for experiments. One widely used type of experiment is neutron scattering. Radiation from the reactor is directed at the material to be studied. The manner in which the radiation interacts and bounces off, or scatters, from the material provides information on structure and properties. Neutron scattering is an important tool in experiments dealing with superconductors, polymers, metals, and proteins.
  • Neutron radiography is another experimental technique. It is similar to medical or dental X-rays. These experiments are used to determine structural integrity and provide quality control for aerospace, automotive and medical components. NRC experts inspect each RTR periodically to ensure they are being operated according to the agency’s safety and security requirements, and the facility’s own license conditions. The NRC uses a graded approach in its inspection program so there are less frequent and detailed inspections at facilities that pose a lower risk.
  • There are two types of inspection programs for operating research and test reactors: • For reactors licensed to operate at power levels of 2 megawatts or greater, the inspection program is completed annually. • For reactors licensed to operate at power levels below 2 megawatts, the inspection program is completed every two years.

Spent Fuel Pools in Japan Survived Disaster, Industry Notes [28Jul11] - 0 views

  • The staff of the Nuclear Regulatory Commission recently produced a list of safety improvements that might be undertaken at American nuclear plants in light of the Fukushima disaster in Japan. On Tuesday, the nuclear industry focused on two elements that were conspicuous by their absence.
  • In a presentation to Wall Street analysts, Marvin Fertel, the president and chief executive of the Nuclear Energy Institute, emphasized that spent fuel pools at the Fukushima Daiichi plant had “survived the accident quite well.”Early in the crisis, which began with an earthquake and tsunami on March 11, American regulators feared that water in one of the pools had almost completely boiled off, and the American Embassy in Tokyo advised Americans to stay 50 miles away. But “the pools may turn out to be a much better story at Fukushima than people envisioned,’’ Mr. Fertel said.
  • Noting that fuel pools at American reactors have far more radioactive material in them than the ones at Fukushima, the accident focused new attention on the idea of moving spent fuel out of the pools and into dry casks, Something already done at most American reactors when they run out of space.That idea first came to prominence after the terrorist attacks of Sept. 11, 2001.
  • ...7 more annotations...
  • But the Nuclear Regulatory Commission staff’s report does not call for moving more of the fuel.When the commission received an oral report from a six-member “task force” it appointed to study the safety implications of Fukushima, one commissioner, William C. Ostendorff, said he had received letters from members of Congress asking for wider use of the casks, however.But Charles L. Miller, who led the task force, replied that removing the fuel would not do much to reduce the basic problem, which is that fuel rods remain in the pool, and if cooling is knocked out, the water that provides protection against melting and the release of radioactive materials will boil away.
  • “Before you can take it out of the pool, it has to be at least five years old, and by that time, we call it, for lack of a better word, cold fuel,’’ Mr. Miller said.At the briefing on Tuesday, Mr. Fertel mentioned other recommendations from the task force, including better instruments for altering operators to how much water is in the pools and new ways of adding water in an emergency. Pulling more fuel out, he said, would provide certain advantages but is also certain to expose workers to radiation in the course of the transfer.
  • Fukushima used dry casks as well, and those appear to have survived without damage, Mr. Fertel said, although they have not been thoroughly inspected. “They’re fine, but so are the pools,’’ he said.
  • They were not unscathed, however; debris flew into the pools after the buildings surrounding them blew up in hydrogen explosions.
  • The task force also refrained from recommending changes in emergency planning zones, despite the embassy’s recommendation during the crisis for Americans to stay 50 miles away from Fukushima. In the United States, emergency evacuation planning is required within 10 miles of any reactor.
  • Mr. Fertel said the recommendation to evacuate to 50 miles “was based not on information, but on the lack thereof.’’
  • Opponents of nuclear power have argued that the commission should cease all extensions of reactors’ operating licenses until it has digested the lessons of the accident in Japan. But Mr. Fertel noted that since March 11, the commission has issued 20-year license extensions for the Vermont Yankee, Palo Verde, Prairie Island, Salem and Hope Creek reactors, and allowed higher power outputs for Limerick and Point Beach.

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.
  • 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.
  • 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.
  • 2. America’s Next Top Energy Innovator
  • 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.

Americans' Support for Nuclear Energy Holds at Majority Level 6 Months After Japan Acci... - 0 views

  • WASHINGTON, Oct. 3, 2011 -- /PRNewswire-USNewswire/ -- Six months after the Fukushima Daiichi accident in Japan, solid majorities of Americans still view nuclear energy favorably, still support the extension of operating licenses at existing facilities that meet federal safety standards, and still believe that construction of a new reactor is acceptable at the site of the nearest nuclear power plant that already is operating, a new national survey shows.While support for nuclear energy has declined from the historically high level seen one year ago, support on a variety of measures is holding at the majority levels found consistently in public opinion surveys conducted throughout the past decade.
  • In the new telephone survey of 1,000 U.S. adults, 62 percent of respondents said they favor the use of nuclear energy as one of the ways to provide electricity in the United States, with 35 percent opposed. Those strongly favoring nuclear energy outnumber those strongly opposed by a two-to-one ratio, 28 percent vs. 13 percent, according to the survey conducted Sept. 22-24 by Bisconti Research Inc. with GfK Roper. The survey was sponsored by the Nuclear Energy Institute and has a margin of error of plus or minus three percentage points. Numerous surveys conducted by Bisconti Research over the past decade show that public support for nuclear energy topped 60 percent each year, rising as high as 74 percent of Americans in March 2010.
  • "While there is some evidence of impact of the Fukushima events, support for nuclear energy continues at much higher levels than in earlier decades," company President Ann Bisconti said. "Turmoil in oil-rich areas of the world and hikes in oil prices historically have focused public opinion even more on nuclear energy, and may have helped to preclude serious impact of events in Japan on public attitudes."Despite the Fukushima accident, 67 percent of Americans rate U.S. nuclear power plant safety high. This is identical to the safety rating found in a national survey last February, one month prior to the earthquake and tsunami that caused the Fukushima accident. Eighty-two percent of Americans believe that "we should learn the lessons from the Japanese accident and continue to develop advanced nuclear energy plants to meet America's growing electricity demand," the new survey showed.

  • Nuclear energy supplies electricity to 20 percent of U.S. homes and businesses, even though the 104 nuclear facilities operating in 31 states constitute only 10 percent of the nation's electric generating capacity.Eighty-five percent of those surveyed agree that, "When their original operating licenses expire, we should renew the license of nuclear power plants that continue to meet federal safety standards." Seven months ago, 88 percent of Americans agreed with this statement.
  • In the latest survey, 59 percent of Americans agree, "We should definitely build more nuclear power plants in the future." Thirty-eight percent disagree. Still, 75 percent of Americans agree that, "Electric utilities should prepare now so that new nuclear power plants could be built if needed in the next decade." Twenty-two percent disagree.Two-thirds of Americans (67 percent) say they would find a new reactor acceptable at the site of the nearest nuclear power plant that already is operating, while 28 percent find this unacceptable. Seven months ago, 76 percent of Americans found this expansion acceptable, with 20 percent saying it was not acceptable.
  • "This survey, like other recent surveys, confirms that large majorities of Americans associate nuclear energy with issues they care about, including clean air, reliable and affordable electricity, energy independence, and economic growth and job creation," Bisconti said.Details on the new survey are accessible at: http://www.nei.org/resourcesandstats/documentlibrary/reliableandaffordableenergy/reports/latest-trends-in-us-public-opinion-about-nuclear-energy-sept-2011.

TVA (Tennessee Valley Authority) progresses with mPower project [17Jun11] - 0 views

  • Generation mPower (GmP) - a partnership between Babcock & Wilcox (B&W) and Bechtel - has signed a letter of intent with the Tennessee Valley Authority (TVA) which defines the project plans for constructing up to six small modular reactors (SMRs) at a site in Tennessee.  
  • In June 2009, B&W announced plans to develop and deploy a scalable, modular nuclear power reactor. The 125 MWe mPower design is an integral PWR designed to be factory-made and railed to site. B&W and Bechtel later entered into a formal alliance to design, license and deploy the design.
  • In its latest Integrated Resource Plan and associated Environmental Impact Statement, published in March 2011, TVA said that it had identified its Clinch River Breeder Reactor site at Oak Ridge, Tennessee, as a potential site for an mPower plant. Studies of the site’s suitability, including environmental issues, were due to begin in late 2010.   The Clinch River Breeder Reactor project was a joint effort of the US government and the country’s electric power industry to design and construct a sodium-cooled fast-neutron nuclear reactor. The project, first authorized in 1970, was terminated in 1983.   The letter of intent signed by GmP and TVA defines the project plans and associated conditions for designing, licensing and constructing up to six mPower units at the Clinch River site. The project is expected to include joint development and pursuit of a construction licence from the US Nuclear Regulatory Commission (NRC). The project would also include engineering, procurement and construction (EPC) activities leading to receipt of an operating licence from the NRC, assuming certain preconditions are met.
  • ...1 more annotation...
  • The letter of intent also specifies the division of responsibilities between GmP and TVA for the preparation and NRC review of a construction licence application. The letter also describes the timing of the projects activities for successful completion of major EPC milestones.   Ali Azad, GmP president and CEO, said, "We have been working with TVA for some time to evaluate the technical and regulatory requirements associated with constructing B&W mPower SMRs at its Clinch River site."   In a statement, B&W said, "GmP remains on track to deploy the first B&W mPower reactor by 2020 at TVA's Clinch River site."   The mPower Integrated System Test (IST) facility in Virginia is expected to soon begin a three-year project to collect data to verify the reactor design and safety performance in support of B&W’s licensing activities with the NRC. TVA plans to submit a construction permit application to the NRC in 2012, while GmP plans to submit a design certification application in 2013.   B&W claims that the "scalable nature of nuclear power plants built around the B&W mPower reactor would provide customers with practical power increments of 125 MWe to meet local energy needs within power grid and plant site constraints."

Georgia residents may pay for Jaczko's antinuclear behavior [07Jul11] - 0 views

  • Georgia Power company stock
  • On a professional level, there is a lot riding on the success of the project to add two new Westinghouse AP1000 reactors to the Vogtle site in eastern Georgia along the Savannah River. It is one of only two remaining projects that is actually moving forward out of the finalists for the first round of loan guarantees initially authorized by the Energy Policy Act of 2005. It is the only project to have actually been awarded a conditional loan guarantee and the one that is most at risk of having a significant schedule interruption if the Nuclear Regulatory Commission dallies even longer in its review process for the completed design certification license application
  • This morning, the Wall Street Journal published Rebecca Smith’s article titled Georgia Eyes Cost Buffer for Nuclear Plant that described how the public utility commission is considering changing the cost recovery rules because they are being pressured by people who think that the project is in danger of a cost and schedule overrun. The company leaders testified that they would have chosen a natural gas project as being “more cost effective” (for the company) if they had known that there was a possibility of the rules of the game being changed six years after the project decision was made
  • ...7 more annotations...
  • I have been involved in the financial analysis of enough large projects to know that there are two sure ways to add cost to any project. The first method is to add delay
  • The second method is to add lawyers to the mix; they are professionally motivated to argue and delay. After all, they bill by the minute.
  • Here is the response that I posted in the comment section of Ms. Smith’s Wall Street Journal article.The sad part of the story was the apparent lack of understanding by the project detractors of the impact of their actions on the cost of the project. The length of time spent building the plant will have a very real impact on the cost of the project due to the fact that more time means more salaries, more interest on borrowed money, and a greater chance of increased prices for materials and equipment purchased and installed at a later time than planned.
  • Maintaining projected costs and schedules is highly dependent on the actions of regulators and intervenors who continue to slow down progress with legalistic arguments that have nothing to do with safety. The issues that the regulators raised are related to a difference of technical opinion on whether or not is reasonable to neglect the impact of solar heating and cooling while modeling the behavior of the containment building after an accident that releases 600 F water and steam into the building.
  • Westinghouse went back and recalculated the impact of the minor term in the equation – the final result was that under absolutely worst case conditions, the final pressure inside the containment went up by about 0.3 psi and was still well below the building’s allowed maximum pressure.
  • The current Chairman of the NRC is a professional political staffer whose complete professional experience following college was working for two avowed antinuclear politicians. He has cost taxpayers in 31 states billions already with his decision to refuse to finish the Yucca Mountain license review; now he is aiming to cost Georgia ratepayers and GA Power investors (remember, utility investors are often widows and orphans) hundreds of millions to billions more. He took the unprecedented step of issuing a press release calling Westinghouse’s application into question over such a technical dispute regarding the significance of terms in a mathematical model.
  • Americans need to know just how job unfriendly the NRC Chairman is.Full disclosure – I work for a company that is designing nuclear reactors that will soon need to be licensed by the Nuclear Regulatory Commission. I fear for my long term employment and that of hundreds of my colleagues and neighbors.

UCS Nuclear Power Safety & Security Recommendations | Union of Concerned Scientists [14... - 0 views

  • Download: U.S. Nuclear Power after Fukushima | U.S. Nuclear Power after Fukushima -- Summary
  • The report outlines and explains 23 specific recommendations, listed below.   = Key recommendation that the NRC should make a top priority. Preventing and Mitigating the Effects of Severe Accidents Extend the scope of regulations to include the prevention and mitigation of severe accidents. Require reactor owners to develop and test emergency procedures for situations when no AC or DC power is available for an extended period. Modify emergency planning requirements to ensure that everyone at significant risk from a severe accident--not just the people within the arbitrary 10-mile planning zone--is protected.
  • Improving the Safety and Security of Spent Fuel The NRC should require plant owners to move spent fuel at reactor sites from storage pools to dry casks when it has cooled enough to do so. The NRC should require reactor owners to improve the security of existing dry cask storage facilities. The NRC should require plant owners to significantly improve emergency procedures and operator training for spent fuel pool accidents Making Existing Reactors Safer The NRC should enforce its fire protection regulations and compel the owners of more than three dozen reactors to comply with regulations they currently violate.
  • ...2 more annotations...
  • Making Existing Reactors More Secure against Terrorist Attacks The NRC should revise its assumptions about terrorists' capabilities to ensure nuclear plants are adequately protected against credible threats, and these assumptions should be reviewed by U.S. intelligence agencies. The NRC should modify the way it judges force-on-force security exercises by assessing a plant's "margin to failure," rather than whether the plant merely passes or fails. The U.S. government should establish a program for licensing private security guards that would require successful completion of a federally supervised training course and periodic recertification. Making New Reactors More Secure against Terrrorist Attacks The NRC should require new reactor designs to be safer than existing reactors. The NRC should require new reactor designs to be more secure against land- and water-based terrorist attacks.
  • Improving the NRC's Cost-Benefit and Risk-Informed Analyses The NRC should increase the value it assigns to a human life in its cost-benefit analyses so the value is consistent with other government agencies. The NRC should require plant owners to calculcate the risk of fuel damage in spent fuel pools as well as reactor cores in all safety analyses. The NRC should not make decisions about reactor safety using probabilistic risk assessments (PRAs) until it has corrected its flawed application of this tool. Ensuring Public Participation The NRC should fully restore the public's right to obtain information and question witnesses in hearings about changes to existing power plant licenses and applications for new licenses.

Fukushima Radioactive Aerosol Dispersion - YouTube [May 2012] - 0 views

  • Published on May 1, 2012 In this dataset, the simulation from NOAA's HYSPLIT model shows a continuous release of tracer particles from 12-31 March at a rate of 100 per hour representing the Cesium-137 emitted from Fukushima Daiichi. Each change in particle color represents a decrease in radioactivity by a factor of 10. Radioactivity decreases due to removal by rainfall and gravitational settling. Decay is not a factor for Cesium in this short duration simulation compared to its 30 year long-half life. The air concentration would be computed from the particle density so it is only partially related to the color scale. The released particles are followed through the end of April using meteorological data from the 1-degree resolution NOAA global analyses. http://sos.noaa.gov/datasets/Atmosphere/fukushima.html Category Education License Standard YouTube License

US LLC Rules Allow Nuclear Power Companies To Take Profits, Dump Risk On Taxpayers [09N... - 0 views

  • US nuclear power plants mostly exist in a legal “get out of jail free” land of LLC (Legal Liability Corporation) ownership. While big energy conglomerates like Entergy own the bulk of the commercial nuclear power plants in the US, these plants are owned by individual LLC companies that have one asset, the power plant. Through a network of LLC companies and holding companies these energy giants are able to suck all the profits out of these nuclear power plants but shoulder none of the risk if something goes bad.
  • The US has a nuclear accident liability law, Price-Anderson. This law sets up a limited fund that all licensed nuclear plant owners would pay into in the event of an accident. They only pay premiums into this fund after an accident happens. Under this law each plant is required to have $300 million in liability insurance that would pay before Price-Anderson would kick in. Proving any other sort of cash reserves, ability to pay for an extended outage or an accident (including Price-Anderson premiums) has been largely voluntary by the power companies. Even when proof of financial assets is asked for by the NRC it is calculated based on projected income estimates done by the power company. The NRC admits they are out of their expertise when it comes to finance and also does no investigation to assure these estimates have any basis in fact. The NRC has also complained repeatedly that deregulation of the energy industry is causing a lack of safety and maintenance to become a large problem as companies try to extract as much profit as possible up and out of these LLC companies to the parent company, leaving insufficient money to safely operate these nuclear plants. Many of these plants in LLC situations are among the aging reactor fleet from the 1960′s & 1970′s. As these plants ask for operating license extensions from the NRC, financial soundness is not part of the review.
  • If a nuclear power plant has a major accident, is found to have an expensive damage situation or is facing decommissioning the LLC that owns it can file for bankruptcy and walk away. The parent company has no financial risk or liability. The NRC has expressed doubt about being able to “pierce the corporate veil” in court and has diverted into settlements every time it has run into this issue with an aging plant facing a financial crisis. The NRC also has no special standing in a bankruptcy case where they can compel Price-Anderson premium payments or for the nuclear power company to pay funds towards decommissioning. It is not totally clear where the decommissioning trust fund lies as these funds are “sold” along with the plant when a new company takes over a nuclear power plant.
