| Title | Auxiliary Feedwater Pump Trip Time Delay Relay Installed Past Evaluated Service Life |
| Description | During the performance of the semi-annual full system lineup inspection sample, the inspectors identified an Unresolved Item (URI) associated with the Unit 2 turbine-driven AFW pump low suction pressure trip time delay relay potentially being past its design service life. During the inspectors review of corrective actions associated with an AFW full system alignment, the inspectors identified a URI associated with a time delay relay that potentially exceeded its design and evaluated maximum service life. The inspectors determined that this was an issue of concern in which more information was needed to determine whether a performance deficiency exists. Specifically, after the inspectors pointed out that the time delay relays were installed beyond the licensees documented evaluation for service life extension, the licensee further extended the relays service life based on historical plant testing. The inspectors needed to evaluate whether the information provided by the licensee was sufficient to provide a technically defensible basis for the additional service life extension. The issue is unresolved pending further agency review of the licensees evaluation (URI 05000301/201500201, Auxiliary Feedwater Pump Trip Time Delay Relay Installed Past Evaluated Service Life). |
