| Title | Invalid Auxiliary Feedwater System Actuation |
| Event Description | This 60-day telephone notification is being made under reporting requirements specified by 10 CFR 50.73(a)(2)(iv)(A) and 10 CFR 50.73(a)(1).
On May 9, 2008, while in a refueling outage, an invalid actuation of the 'A' Auxiliary Feedwater train occurred while performing the Turbine Trip and Auxiliary Governor Solenoids Operability Check. The cause of the event was a failure of the 'A' Motor Driven Auxiliary Feedwater Pump (MDAFWP) bypass control relay, 63XT3-TDA. The relay failed to operate as designed under the system conditions and configuration specified by the procedure, resulting in an actuation signal. No actual plant condition existed which required an Auxiliary Feedwater actuation. The event resulted in the complete actuation of the 'A' Motor Driven Auxiliary Feedwater train. All equipment functioned as designed for the existing plant configuration. Relay 63XT3-TDA was replaced and retested per the appropriate R. E. Ginna work control processes. The licensee notified the NRC Resident Inspection. |
