Title | Unusual Event - Loss of Off-Site Power While Defueled |
Event Description | At 1020 CDT on 4/7/08 a loss of off-site power was experienced due to maintenance work in the switch yard. At 1033 CDT the licensee declared an Unusual Event. Presently, off-site power is in the process of being restored . The "B" Emergency Diesel Generator is running and loaded, while the "A" Emergency Diesel Generator and "A" bus is tagged out of service for maintenance. The Essential Service Water system developed a leak in the end bell of a cooling unit, which in turn caused licensee to secure control room cooling. This put the licensee in LCO 3.7. The plant is currently defueled. Spent fuel pool cooling has been reestablished.
The licensee notified the NRC Resident Inspector. Licensee will be contacting other state, local, and government agencies, and will be issuing a press release.
At 1250 CDT, normal off-site power was restored to NB02 and the Unusual Event was terminated. The "B" Emergency Diesel Generator was secured and placed in standby. The licensee has notified the state and local emergency response organizations and will be notifying the NRC Resident Inspector. Notified R4DO(Lantz), NRREO (Ross-Lee), IRD (Cruz), DHS (Akers), and FEMA (Biscoe). |
