| Title | Inadequate Revision for Technical Requirement Manual Section |
| Description | A finding of very low safety-significance (Green) and associated Non-Cited Violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedure, and Drawings was identified by the inspectors for the licensees failure to ensure that specific requirements of the Technical Requirement Manual (TRM) Section 3.8.b. would be performed as written. Specifically, the licensee inappropriately revised the applicability section of TRM 3.8.b. and added that the TRM actions were applicable when the circuit breaker associated with an inoperable protective device was closed and receiving power from an energized source. This revision did not ensure that verification of circuit breaker position would be performed on a periodic basis when/if the breaker was open. The licensee subsequently entered the issue into their corrective action program as AR 00961522. The finding was determined to be more than minor because the finding, if left uncorrected, would become a more significant safety concern. The revised applicability section of TRM 3.8.b did not ensure that necessary action, i.e. verification of circuit breaker position, would be performed to ensure that primary containment electrical penetrations would not be subject to excessive fault currents. The finding was of very low safety-significance based on a Phase 1 screening in accordance with IMC 0609, Appendix A, Significance Determination of Reactor Inspection Findings for At-Power Situations. This finding was not associated with a cross-cutting aspect because the finding was not indicative of the licensees current performance. |
