| Title | Inadequate Corrective Actions to Address Water Intrusion in the HCV-09-2A Relay Box |
| Description | A self-revealing, Non-Cited Violation (NCV) of 10 CFR Part 50 Appendix B, Criterion XVI, Corrective Action, was identified for the licensees failure to correct an identified condition adverse to quality associated with the water intrusion into the HCV- 09-2A relay box. The licensees failure to implement corrective actions to address previous water intrusion events was a performance deficiency. Specifically, the licensee failed to implement corrective actions to address previous water intrusion events, which resulted in the failure of HCV-09-2A, and a plant trip. This issue was documented in the licensees corrective action program as CR 1920696. Immediate corrective actions included the restoration of HCV-09-2A to operable status and the inspection of other Main Feedwater Isolation Valve (MFIV) relay boxes. This performance deficiency was more than minor because it was associated with the equipment performance attribute of the Initiating Events Cornerstone and it adversely affected the associated cornerstone objective of limiting the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. In accordance with the NRC inspection Manual Chapter 0609, Attachment 4, Initial Characterization of Findings, the finding was determined to be of very low safety significance (Green) because the finding did not result in a loss of mitigation equipment relied upon to transition the plant from the onset of the trip to a stable shutdown condition. The finding had a cross-cutting aspect in the area of Problem Identification and Resolution, in the component of Evaluation, because the licensee failed to thoroughly evaluate issues to ensure that resolutions address causes and extent of conditions commensurate with their safety significance (P2). |
