| Title | Pressurizer Heater Breaker Installation That Would not have Functioned During Certain SSFCredited Events |
| Description | A licensee-identified potentially greater than Green apparent violation of 10 CFR 50, Appendix B, Criterion III, Design Control, was identified when the licensee failed to maintain design control of the Standby Shutdown Facility. Because the safety significance of this finding is potentially greater than Green, it is being treated as an NRC identified finding. The failure to maintain design control of the SSF was a performance deficiency. The PD was more than minor because it was associated with the Mitigating Systems Cornerstone attribute of Design Control and adversely affected 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. A Phase III analysis was required because the finding involved the loss or degradation of equipment designed to mitigate external initiating events. A cross-cutting aspect was not identified because the finding does not represent current plant performance. |
