| Title | |
| Description | A self-revealing finding was identified for the failure to maintain a preventative maintenance (PM) procedure for circuit breakers current with industry information and operating experience (OE), as required by procedure, DNAP-2001, Equipment Reliability Process, Revision 0. The licensee entered this problem into their corrective action program as condition report 331819. The inspectors determined that the failure to maintain PM procedures for circuit breakers current with industry information and OE was a performance deficiency (PD). This PD had a credible impact on safety due to an original equipment main contactor which was in service for approximately 35 years, and subsequently experienced a coil failure with a consequent fire. The PD was more than minor because it could be reasonably viewed as a precursor to a significant event based on fire development leading to the loss of other safety-related equipment. In accordance with NRC Inspection Manual Chapter 0609, Significance Determination Process, the inspectors performed a Phase 1 analysis and determined the finding required a Phase 3 analysis by a regional senior reactor analyst. The significance of this finding is to-be-determined (TDB) pending completion of a phase 3 evaluation. This finding involved the cross-cutting area of corrective action, the component of the OE, and the aspect of implementation and institutionalization of OE through changes to station processes and procedures, P.2(B), because the licensee failed to incorporate existing industry OE to ensure procedural guidance was adequate for testing of the main contactor.
