| Title | Failure to Maintain SSF Pressurizer Heater Breakers as Safety-Related Components |
| Description | An NRC-identified non-cited violation of 10 CFR 50, Appendix B, Criterion III, Design Control, was identified for the licensees failure to maintain the Standby Shutdown Facility pressurizer heater breakers and associated electrical components as safety-related components or seismically-qualified as specified in the SSF licensing basis documents. The failure to maintain SSF systems, structures, and components as safety-related and seismically-qualified as required by the SSF licensing basis was a performance deficiency. This PD was more than minor because it was associated with the Mitigating Systems Cornerstone attribute of Configuration Control and adversely affects the cornerstone objective in that failure to maintain equipment qualification did not provide reasonable assurance that the SSF Auxiliary Service Water subsystem would perform its safety function. The finding was of very low safety significance because the finding involved a design or qualification deficiency confirmed not to result in loss of operability or functionality. The PD directly involved the cross-cutting aspect of thoroughly evaluates problems such that the resolutions address causes and extent of conditions, as necessary including evaluating for operability in the Corrective Action Program component of the Problem Identification and Resolution cross-cutting area for not properly evaluating an immediate determination of operability. |
