Finding

Title

Turbine-Driven Auxiliary Feedwater Pump Trip

Description

The inspectors identified an Unresolved Item (URI) for failure of the turbine-driven auxiliary feedwater (TDAFW) pump during a surveillance test on May 10, 2011. Specifically, the overspeed trip device actuated for no apparent reason, shutting the pump down. On May 10, 2011 the licensee was operating the TDAFW pump for a surveillance test. Approximately 3 minutes into the test run, the trip lever became unseated from the knife edge, resulting in closure of the trip valve. By design, the trip lever is part of the mechanical overspeed trip. The licensee validated that an overspeed condition did not exist by independent means including feedflow and shaft speed. In addition, the licensee ruled out human error; i.e. operator contact with the trip mechanism. The licensee discovered improper application of grease on the knife edge from an earlier maintenance outage and believes the presence of the grease resulted in the pump trip. The licensee is performing an analysis to validate that greasing of the knife edge caused the pump trip. Pending completion of the report on the analysis of the trip lever and the licensees evaluation of the results, this issue will be classified as a URI. URI 05000255/2011003-04, Turbine-Driven Auxiliary Feedwater Pump Trip.
