NRC: 83% of Power Plants Show Strong Performance

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.

Later this spring and summer, the NRC will meet publicly in locations near the plants to discuss plant issues. A separate announcement will be issued for each of these meetings. In addition to the annual assessment letters, plants also receive an NRC inspection plan for the coming year. Updated information on plant performance is posted to the NRC Web site every quarter. The plants also receive a mid-cycle assessment letter during the year; the next mid-cycle letters will be issued in September.
