The inspectors identified a Green non-cited violation (
NCV) of
10 CFR Part 50, Appendix B, Criterion III, Design Control, for the licensees failure to verify the adequacy of defined shelf life and design life characteristics of Class 1E electrical equipment. The issue was entered into the licensees corrective action program as CR 1064785. The inspectors determined that the performance deficiency was more than minor because it was associated with the Design Control attribute of the
Mitigating Systems Cornerstone and the failure to ensure the Class 1E static and dynamic performance characteristics were identified and evaluated adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of the
SSCs that responds to
initiating events to prevent undesirable consequences. The finding was determined to have a cross-cutting aspect in the change management area of Human Performance [H.3] because Leaders failed to use a systematic process for evaluating and implementing change so that nuclear safety remains the overriding priority.
