| Title | Licensee-Identified Violation |
| Description | Section 4OA5.2, on January 7, 2009, following installation and post work testing of an additional backup nitrogen supply to the ADVs, Entergy personnel identified that surveillance tests for the nitrogen backup supplies to the ADVs were never performed contrary to TS surveillance requirement 3.3.4.2.The inspectors determined this constituted a violation of TS 3.3.4, Remote Shutdown, which includes the TS surveillance requirement to verify that the nitrogen backup supply control circuit and transfer switch to the steam generator ADVs are capable of performing their intended function. Contrary to this requirement, Entergy personnel did not verify the functionality of the control circuitry associated with the nitrogen backup supply to the ADVs. The inspectors determined this issue was of very low safety significance (Green) per SDP Phase 1 screening because the safety function of the ADVs was not lost. Specifically, the inspectors determined the remote shutdown function for the steam generator requires only one ADV to be operable. All four ADVs were capable of being operated with the normal station air supply. Entergy personnel entered the issues into the corrective action program as CR-IP2-2009-00062, -00069, -00077, -00137, and -00983 |
