The Nuclear Regulatory Commission has issued annual assessment letters to the nation's 104 operating commercial nuclear power plants. All the plants continue to operate safely. "Our ongoing assessment of nuclear power plant performance is at the heart of the agency's mission of protecting people and the environment," said Eric Leeds, director of the Office of Nuclear Reactor Regulation. "The 2008 year-end results show that about 83 percent of the plants are performing strongly enough that we're satisfied with our basic level of inspections at those sites." If a nuclear power plant's performance declines, the NRC increases the level of inspection to ensure the plant operator is taking the steps necessary to correct the situation. The additional amount of inspection is commensurate with the level of plant performance. At the close of last year, only one reactor, Unit 3 at Palo Verde (Ariz.), required the NRC's highest level of attention. Three reactor units, Cooper (Neb.) and Units 1 and 2 at Palo Verde (Ariz.), required significant NRC attention. And another 14 reactor units, Units 1 and 2 at Byron (Ill.), Unit 1 at Comanche Peak (Texas), Unit 1 at Farley (Ala.), Unit 1 at Grand Gulf ( Miss.), Unit 2 at Hatch (Ga.), Kewaunee (Wis.), Units 1 and 2 at McGuire (N.C.), Unit 2 at Nine Mile Point (N.Y.), Unit 1 at Oconee (S.C.), Palisades (Mich.), Unit 1 at Prairie Island (Minn.), and Unit 2 at San Onofre (Calif.), required additional attention beyond the basic level.

"A rash of recent failures in the buried piping systems of nuclear reactors - including one at San Onofre Nuclear Generating Station - has prompted three congressmen to ask the Government Accountability Office to investigate "the integrity, safety, inspection, maintenance, regulations and enforcement issues surrounding buried piping at our nation's nuclear power plants," according to a public statement Thursday. "Under current regulations, miles and miles of buried pipes within nuclear reactors have never been inspected and will likely never be inspected," said Rep. Edward Markey, D-Mass. (who chairs the Energy and Environment Subcommittee) in the statement. "This is simply unacceptable. As it stands, the NRC requires - at most - a single, spot inspection of the buried piping systems no more than once every 10 years. This cannot possibly be sufficient to ensure the safety of both the public and the plant.""

I was appalled at the NRC chairman Jaczko's press briefing yesterday when asked point blank how many nuclear reactors in the US were near faults… Instead of answering the question he said that all reactors near faults designed withstand both quakes and tsunami events. There was no follow-up question as to whether or not this country's evacuation plans would do any better than Japans.
