Aging Reactors

New England Coalition on Nuclear Pollution submits emergency petition to NRC, August 27, 2007

NIRS comments to the California Energy Commission on Nuclear Power in California; calling for opposition to relicensing of Diablo Canyon and San Onofre and discussion of nuclear power/global warming. August 12, 2005

NIRS presentation March 08, 2005 to the U.S. NRC Regulatory Information Conference workshop on “Pro-active Management of Material Degradation” in nuclear power stations which focuses on the incidence of failed and leaking fuel in operating reactors.

Anywhere from 25% to 33% of the nation’s nuclear power stations are operating with failed and leaking nuclear fuel in the reactor core. NIRS and Union of Concerned Scientists jointly wrote the Commission on 02/28/2005 questioning the adequacy of NRC enforcement policy in light of a rising trend in nuclear fuel cladding failures in U.S. reactors.

NRC Pulls Fast One on Public Meeting for Davis-Besse Restart Appeal. Press Release. August 17, 2004.

The United States Government Accountability Office reports (May 2004) on the botched federal oversight of the near-miss accident at Davis-Besse nuclear power station outside Toledo, Ohio. FirstEnergy put electricity production ahead of maintaining safety by ignoring multiple warning signs of severe corrosion of the reactor vessel head in what could have resulted in a nuclear accident far worse than Three Mile Island with as little as 2 months operational margin remaining.

NIRS presented to NRC Safety Research Conference October 22, 2003 on a panel discussion of “Material Degradation: Present and Future Directions” where NIRS revealed that a federal laboratory tests of mock-ups of the severely corroded as found Davis-Besse reactor pressure vessel head burst at less than the reactor’s normal operational pressure.

Vermont Yankee Cooling Tower Collapses. A portion of a cooling tower at the Vermont Yankee reactor collapsed Wednesday, August 22. A broken 52” pipe was photographed spewing water into the ground, in the latest embarrassment for Yankee owner Entergy Corporation, the nation’s second-largest nuclear utility. More pictures here.

NRC and FirstEnergy were in possession of this photo of Davis-Besse reactor vessel head taken during the April 2000 refueling and maintenance outage just prior to allowing the reactor restart for its operational run to the February 16, 2002 shutdown. Photo clearly indicates extensive corrosion occurring on vessel head.

NIRS speech to the U.S. Nuclear Regulatory Commission Regulatory Information Conference April 14, 2003 workshop focuses on material degradation of reactor internal components.

NIRS comments July 2003 to NRC in support of communications that strengthen requirements for inspection of deteriorating steam generator tubes in Pressurized Water Reactors.

NIRS fact sheet July 2003 focuses on the sudden and unexpected discovery of cracking of stainless steel penetration sleeves in the bottom reactor vessel head at South Texas Project nuclear generating station.

NIRS letter June 2003 to NRC Commission Chair Nils Diaz in follow-up to NIRS presentation to NRC Commissioners February 2003 conveying continued concern that the federal nuclear safety agency has not learned the most significant lesson from the near miss accident at Davis-Besse nuclear station (2002) regarding failure to enforce safety guidelines and an agency Order in a gamble to give FirstEnergy more production time.

NIRS letter February 2003 to NRC Commissioner Chair Meserve (soon to resign) in follow-up to NIRS presentation to Commission February 2003 conveying continued concern that the federal nuclear safety agency ducked its own safety guidelines in deference to a utility production agenda narrowly missing a potentially catastrophic nuclear accident in 2002 at Davis-Besse.

NIRS presented February 2003 to the Commissioners of the U.S. Nuclear Regulatory Commission its concerns with the near-miss accident of the Davis-Besse nuclear power station and the agency’s abandonment of its safety principles for an industry production agenda.

Office of Inspector General Report on NRC/First Energy deficiences at Davis-Besse, December 30, 2002

NIRS comments November 2002 in response to the U.S. Nuclear Regulatory Commission’s Davis Besse Lessons Learned Task Force Final Report outlining how the NRC lack of oversight and enforcement in the near miss accident at Davis-Besse 2002 has significantly undermined public confidence in the federal nuclear safety agency.
