A self-revealing apparent violation (AV) o … A self-revealing apparent violation (AV) of 10 CFR 50 Appendix B, Criterion XVI, Corrective Action, was identified because Entergy did not promptly correct an adverse condition resulting in the failure of the B emergency diesel generator. Specifically, Entergy personnel did not promptly replace a degraded jacket water flange gasket prior to its subsequent failure. Entergys corrective actions included replacing the gasket, visually inspecting the other jacket water connections, and initiating condition report CR-VTY-2012- 05044. The finding is more than minor because it is associated with the Equipment Performance attribute of the Mitigating Systems cornerstone and affected the cornerstone objective to ensure the availability and reliability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). Specifically, the B emergency diesel generator failed in service due to a known degraded condition that affected the overall system redundancy and reliability and resulted in 37 days of unplanned unavailability. The significance of the finding is designated as To Be Determined (TBD) until a Phase 3 analysis can be completed. The finding had a cross-cutting aspect in the Human Performance, Decision-Making because Entergy personnel did not use conservative assumptions in decision making in that the chosen action was to monitor the leak for a prolonged period of time.r the leak for a prolonged period of time. +
