| Title | Inadequate Corrective Actions for Repetetive Failures of a Risk-Significant Valve |
| Description | The inspectors identified a Green finding for inadequate corrective actions, which resulted in a plant transient. Specifically, prior corrective actions were ineffective at preventing repeated failures of condensate makeup control Valve,LCV-1190, a condition which had the potential to initiate a secondary plant event and/or adversely affect mitigating systems equipment (e.g., impacting the availability of the diesel-driven auxiliary feedwater Pump FW-54.)The finding was greater than minor because the random failure of LCV-1190 could be reasonably viewed as a precursor to a significant event. The finding, which is under the Initiating Events cornerstone, was of very low safety significance because it did not (1) result in exceeding the Technical Specification limit for reactor coolant system leakage, (2) contribute to both the likelihood and a reactor trip and that mitigation equipment would be unavailable, or (3) increase the likelihood of a fire or flood. This finding had a crosscutting aspect in problem identification and resolution, specifically the evaluation aspect P.1.(c) because, as Inspection Manual Chapter 0305 states, licensees should thoroughly evaluate problems such that the resolutions address the causes and extent of condition... Based on the inspectors review of the previous events, the cause determinations lacked rigor and directly led to the recurrence of this condition. (Section 4OA2 |
