Title	Telephone Notification in Lieu of Written Ler - Invalid Actuation of Motor Driven Auxiliary Feedwater Pump
Event Description	Event: Invalid actuation of the 'B' Motor Driven Auxiliary Feedwater (MDAFW) pump. Report Type: This 60-day telephone notification is being made under 10CFR50.73(a)(2)(iv)(A) and 10CFR50.73(a)(1). Description: On November 10, 2010, the 'A' Main Feedwater Pump (MFP) was started per plant operating procedures. When the 'A' MFP was started, there was a partial activation of the Auxiliary Feedwater System with the start of the 'B' MDAFW. The plant was in Mode 3 after completing refueling outage 16 during this event. Actual plant conditions and parameters did not exist that required an automatic start of the 'B' MDAFW pump. Therefore, this actuation is classified as invalid. The system started and functioned successfully. This invalid actuation was entered into the corrective action program as NCR-432566. The licensee notified the NRC Resident Inspector.
