| Title | Failure to Follow Procedures During the Battery Performance Tests |
| Description | The team identified a noncited violation of 10 CFR 50, Appendix B, Criterion V, Instruction, Procedures, and Drawings, for failure to follow procedures while performing the battery performance tests. Specifically, on four occasions, performance tests for Battery 2B008 were terminated early instead of continuing the tests until reaching one of the test termination criteria in the applicable test procedure. The licensee has entered this into their corrective action program as Notification NN 200060319. This finding was more than minor because it was associated with the mitigating systems cornerstone (equipment performance attribute) and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using the Inspection Manual Chapter 0609, Significance Determination Process, Phase 1 Worksheets, the finding is determined to have very low safety significance (Green) because it was not a design issue resulting in loss of function, did not represent an actual loss of a system safety function, did not result in exceeding a Technical Specification allowed outage time, and did not affect external event mitigation. This finding has a cross-cutting aspect in the area of human performance (Work Practices component) because the licensee did not ensure that appropriate error prevention techniques were used to avoid deviation from the test termination criteria provided in test procedures [H.4.(a) |
