"On November 30, 2006, at approximately 14:45 hours, an Auxiliary Feed Water (AFW) System actuation signal was generated as a result of maintenance activities on the 21 Main Boiler Feed Pump (MBFP). Both motor driven AFW pumps were running at the time and were not automatically started due to previously being placed in service to provide feed water flow to the steam generators. The actuation signal isolated the Steam Generator blowdown Containment Isolation Valves. Both MBFPs were isolated and not feeding the steam generators at the time the actuation signal was generated. The plant was in Mode 3 (Hot Standby) for a forced outage and 21 MBFP was in a maintenance / test condition. The automatic actuation occurred due to the reset oil pressure lowering below the trip set point and initiating an automatic actuation signal."
The licensee notified the NRC Resident Inspector.
