Safety

Nuclear safety is, of course, an oxymoron. Nuclear reactors are inherently dangerous, vulnerable to accident with the potential for catastrophic consequences to health and the environment if enough radioactivity escapes. The U.S. Nuclear Regulatory Commission, Congressionally-mandated to protect public safety, is a blatant lapdog bowing to the financial priorities of the nuclear industry.

Coalition cites catastrophic risk of Palisades RPV fracture, appeals ASLB ruling to full NRC Commission

Japan's worst embrittled RPV, at Genkai 1, has been permanently closed in the aftermath of Fukushima.Citing the risks of reactor pressure vessel (RPV) fracture, core meltdown, and catastrophic release of hazardous radioactivity at Entergy's Palisades atomic reactor in southwest Michigan, an environmental coalition (Beyond Nuclear, Don't Waste MI, MI Safe Energy Future, and Nuclear Energy Info. Service of IL) has appealed an Atomic Safety and Licensing Board (ASLB) panel's adverse ruling to the full U.S. Nuclear Regulatory Commission (NRC).

The coalition's legal counsel, Toledo-based attorney Terry Lodge, filed the appeal on June 2nd.

Arnie Gundersen, Chief Engineer at Fairewinds Associates, Inc. in Burlington, VT, serves as the coalition's expert witness on the risks of pressurized thermal shock (PTS) causing "brittle fracture" in the Palisades RPV. Gundersen and Fairewinds Energy Education have produced a short, humorous, educational video about PTS risks entitled "Nuclear Crack Down?"

NRC has admitted on numerous occassions that Palisades has the worst neutron radiation embrittled RPV in the country. Palisades first surpassed embrittlement safety standards in 1981, just ten short years into its operations. NRC, and/or the nuclear utilities owning and operating Palisades, have previously predicted various "End of Life" dates for the problem-plagued atomic reactor, the earliest being 1995. However, as reported by Jeff Donn of AP in 2011, NRC has weakened safety regulations time after time, to accommodate the age-degraded nuclear power plant, one of the oldest still operating in the U.S.

See updates on Beyond Nuclear et al.'s intervention against Entergy Palisades' License Amendment Request for regulatory relief dating back to Dec. 1, 2014 at the Reactor Safety website section.

Amidst worldwide warnings, Beyond Nuclear challenges regulatory rollbacks on reactor vessel risks

Japan's worst embrittled RPV, at Genkai 1, has been permanently closed in the aftermath of Fukushima.Worldwide warnings about atomic reactor pressure vessel (RPV) risks have elicited little more than a yawn from the U.S. Nuclear Regulatory Commission (NRC). While the French nuclear establishment admits very serious fabrication flaws in brand new RPV components in France (with potential implications for new reactors under construction in China and Finland as well), and the Belgian nuclear regulatory chief warns about apparent age-related RPV degradation that should be guarded against globally, NRC is moving to further weaken already severely weakened RPV safety standards in the U.S.

In a major June 2011 exposé by investigative reporter Jeff Donn, the Associated Press cited RPV safety standard rollbacks as a top example of NRC complicity with the nuclear power industry to keep aging nukes operating, despite the increasing risks. In fact, Donn interviewed the NRC whistleblower who first brought RPV embrittlement/pressurized thermal shock meltdown risks to light more than 30 years ago. And Donn also identified NRC's pat excuse for such regulatory rollbacks: supposedly unnecessarily- or over-conservative safety margins, that NRC chips away at, while continuing to express confidence that "reasonable assurance of adequate protection" of the public health, safety, and environment is being maintained.

A year later, the Japanese Parliament, in the first independent investigation in its history, concluded that the root cause of the Fukushima Daiichi nuclear catastrophe -- the reason the atomic reactors were so very vulnerable to the natural disasters that destroyed them -- was collusion between supposed safety regulator, nuclear power industry, and government/elected officials.

Beyond Nuclear, along with environmental allies, has challenged such attempted regulatory rollbacks at the worst embrittled RPV in the U.S., Entergy Nuclear's Palisades atomic reactor, on the Lake Michigan shore in s.w. MI. Although an NRC licensing board rejected the groups' intervention last week, the coalition has vowed to fight on. Its legal counsel, Toledo-based attorney Terry Lodge, has indicated an appeal will be forthcoming by the 25 day deadline.

Beyond Nuclear also just submitted extensive comments, based on years -- and even decades -- of past watch-dogging work, regarding brittle RPV fracture risks, in opposition to NRC's latest moves to weaken standards yet further.

Beyond Nuclear's expert witness in the Palisades proceeding, Arnie Gundersen, has prepared a short, humorous educational video about pressurized themal shock risks entitled "Nuclear Crack Down?" Gundersen serves as Chief Engineer at Fairewinds Energy Education.

The coalition also has a second RPV-related contention against Palisades still in process. On March 9th, Beyond Nuclear et al. intervened against Entergy and NRC's collusion to also weaken RPV ductile tearing failure risks at the problem-plagued Palisades, as well.

Beyond Nuclear comments on NRC move to weaken RPV fracture safety regulations

A diagram describing pressurized thermal shock in a nuclear reactor. Credit: Japan Atomic Energy Agency. Japan's worst embrittled RPV, at Genkai 1, has been permanently closed in the aftermath of Fukushima.Beyond Nuclear has submitted a dozen official public comments into the U.S. Nuclear Regulatory Commission's (NRC) proceeding regarding the development of Draft Regulatory Guide 1299 (DG-1299), and its technical background document, NUREG-2163. Both DG-1299 and NUREG-2163 are part of NRC's regulatory rollback, known as 10CFR50.61a, a weakening of (already weakened) safety standards contained in 10CFR50.61 (Title 10, Code of Federal Regulations, Parts 50.61 and 50.61a).

10CFR50.61a, or alternate fracture toughness rules for neutron radiation embrittled reactor pressure vessels (RPVs), would increase the risks of a pressurized thermal shock (PTS) through-wall breach, Loss-of-Coolant-Accident, core meltdown, containment failure, and catastrophic radioactivity release to the environment.

On Dec. 1, 2014, Beyond Nuclear and coalition partners Don't Waste MI, MI Safe Energy Future--Shoreline Chapter, and Nuclear Energy Information Service of Chicago, intervened against Entergy Nuclear's License Amendment Request for 10CFR50.61a regulatory relief at its Palisades atomic reactor in southwest MI. Terry Lodge serves as the coalition's legal counsel.

Beyond Nuclear on Thom Hartman's "The Big Picture" re: Indian Pt. fire/oil spill & Chinese proliferation concerns

Thom Hartmann, host of "The Big Picture," had Beyond Nuclear's Kevin Kamps on to discuss the transformer fires at Entergy Nuclear's Indian Point nuclear power plant, and consequent oil spill into the Hudson River upstream from New York City. Thom and Kevin also discussed the Obama administration's attempt to extend approval of nuclear power commerce with China, despite congressional concerns about dual-use technology that could be transferred to China's nuclear submarines, as well as "vertical" and "horizontal" proliferation concerns from reprocessing plutonium (adding to China's own nuclear arsenal, or the spread of nuclear weaponry to other countries or terrorist groups, respectively). (See the segment from the 46:00 minute mark to the 52:15 minute mark.)

Transformer fire at Entergy Nuclear's Indian Point causes thousands of gallons of oil to leak into Hudson River upstream of New York City

As reported by CBS New York, a transformer fire took place at Entergy Nuclear's Indian Point Unit 3 (IP) yesterday. New York Governor Cuomo rushed to the scene, concerned about the potential for leaking oil to reach the Hudson River.

Sure enough, it has. As reported by ABC News, the multiple fires did lead to an oil slick on the Hudson River, when an oil overflow tank's capacity was not enough to stem the leakage. Thousands of gallons of oil have reportedly leaked into the river, some 30 miles north of New York City.

Riverkeeper issued a press release, as well as photos (see left), stating that this latest accident is proof positive that IP should be permanently closed.

Beyond Nuclear just took part in an anti-nuclear summit very near Indian Point, held at Stony Point Conference Center on May 3rd. Hosted by Hudson River Sloop Clearwater, the event focused on high-level radioactive waste (HLRW) and decommissioning issues. Beyond Nuclear's presentation addressed HLRW risks at IP, including radioactive leaks from IP's HLRW storage pools, documented in a Beyond Nuclear report and backgrounder. Representatives from NIRS, Citizens Awareness Network, Indian Point Safe Energy Coalition, and Riverkeeper also presented.
