| Title | Licensee-Identified Violation |
| Description | TS 3.7.1 requires that all MSSVs shall be operable, which, in part, is specifically met if as-found lift setpoints are within applicable acceptance criteria during inservice testing. Contrary to this requirement, on March 8, 2011, during performance of MSSV testing, Entergy personnel identified that MS-45-1 and 483 exceeded as-found lift setpoints. Entergy subsequently performed satisfactory adjustments and as-left testing to ensure operability was restored. Entergy documented this issue in the corrective action program for resolution under condition report CR-IP3-2011-00960. In addition, Entergy personnel analyzed the past operability and associated impact on the safety analysis with two MSSVs potentially lifting greater than the allowable setpoints. Although two MSSVs were determined to be inoperable for an unknown duration, and potentially longer than the allowed outage time listed in the Unit 3 technical specifications, the inspectors determined that this finding is of very low safety significance because it did not increase the probability or consequences of any anticipated operational occurrence or accidents covered by the safety analysis. |
