The Nuclear Regulatory Commission said today the finding means increased oversight and inspection of Duke Energy’s Oconee Nuclear Station near Seneca.
This summer, Oconee engineers determined pressurized heater breakers used in the station’s standby shutdown facility were not working properly. That facility is designed to shut down the plant in case something like a tornado or flood means normal shutdown modes can’t be used.
Oconee spokeswoman Sandra Magee says the problem was fixed promptly, and Duke is not appealing the findings.
The NRC met with Duke officials last month to talk about the plant’s safety issues. NRC officials are coming back to Oconee in January for a follow-up inspection.
