EMERGENCY OPERATIONS FACILITY (EOF) LOST POWER FOR 1.5 HOURS DURING POWER SUPPLY SHIFT
This licensee made this notification as an information call.
The backup emergency diesel generator (EDG) for the EOF failed to automatically start when offsite power was lost during a planned transfer of power. The offsite power supply breaker hung during the transfer causing the loss of power and the backup EDG did not start. The licensee is investigating both problems.
The licensee intends to notify the NRC Resident Inspection.
