| Title | Inadequate Test Control of Safety Related Batteries |
| Description | The team identified a finding of very low safety significance involving a non-cited violation (NCV) of 10 CFR Part 50, Appendix B, Criterion XI, Test Control, because Entergy did not adequately perform battery discharge testing and assure that the battery discharge test procedures incorporated requirements contained in applicable design documents for multiple cycles of Technical Specification (TS) required surveillance testing of the station batteries. Specifically, test results have been negatively impacted because of improper use of battery test equipment and tests had errors with load profiles. Entergy entered these issues into the corrective action program to evaluate and correct the deficiencies in the battery testing program and ensure any future testing requirements are met. The performance deficiency was determined to be 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 availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The team evaluated the finding in accordance with IMC 0609, Significance Determination Process, Attachment 0609.04, Phase 1 - Initial Screening and Characterization of Findings. The team determined the finding was of very low safety significance 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 a seismic, flooding, or severe weather initiating event. This finding had a cross-cutting aspect in the area of Human Performance, Resources Component, because Entergy did not ensure that complete, accurate, and up-to-date procedures were available and adequate to assure nuclear safety. Specifically, the battery discharge test procedures did not ensure that capacities were correctly measured and service test profiles were correctly translated from the battery design calculations.
