| Title | Inadequate Procedures for Testing 33 Station Battery |
| Description | The inspectors identified a finding of very low safety significance (Green) involving a non-cited violation (NCV) of 10 CFR 50, Appendix B, Criterion XI, Test Control, because Entergy personnel did not properly document and evaluate test results to ensure that the test requirements were satisfied. Specifically, Entergy personnel did not ensure that the 33 battery modified performance test procedure prescribed the correct vendor discharge rate and that the 33 battery load profile service test and the 33 battery modified performance test prescribed the correct design peak (one minute) load profile amperage. Entergy personnel entered this issue into the corrective action program to evaluate and correct the deficiencies in the battery testing program, perform an extent of condition review, and evaluate the risk associated with delaying testing of the 33 battery until the next refueling outage. The finding was more than minor because it was similar to NRC IMC 0612, Appendix E, Examples of Minor Issues, Example 2.c, in that the test control issue was repetitive through multiple performances of the surveillance test over a course of six years. Additionally, the finding was more than minor because it was associated with the procedure quality attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective of ensuring the reliability and capability of systems that respond to initiating events to prevent undesirable consequences. The finding was of very low safety significance (Green) because it was not a design or qualification deficiency, did not represent a loss of system safety function, and did not screen as potentially risk significant due to external events. There was not a cross-cutting aspect associated with this finding because the performance deficiency is not reflective of current performance. Specifically, the inspectors determined that Entergy personnel did not adequately implement their modification process when they did not update their test procedures in 2005, following the modification to the 33 station battery. |
