Finding

Title

Failure of the A Standby Liquid Control Train

Description

An unresolved item (URI) was opened related to the failure of the Standby Liquid Control (SBLC) A pump relief valve during system testing. The performance deficiency cannot be determined until the definitive causers) of the issue are known. On July 10, 2009, during the quarterly surveillance on the A SBLC train, the pump relief valve, PSV-1105A, lifted and failed to reseat, which diverted flow such that the system could not meet its TS acceptance criteria. The train was declared inoperable, the relief valve was replaced, and the system was restored to service on July 12, 2009. This issue has been entered into Pilgrim\'s CAP (CR-PNP-2009-03088) and an apparent cause evaluation (ACE) was conducted. However, Entergy has determined that the ACE may not definitively address the causers) of the SBLC train failure. The inspectors require Entergy\'s final ACE in order to evaluate whether or not a performance deficiency exists.URI 05000293/2009004-03, Failure of the A Standby Liquid Control Train
