| Title | Failure to Promptly Identify and Correct an Oil Leak on the HPCS Waterleg Pump |
| Description | A finding of very low safety significance and associated NCV of Title 10 of the Code of Federal Regulations (CFR) Part 50, Appendix B, Criterion XVI, Corrective Action, was identified by the inspectors for the failure to promptly identify and correct a condition adverse to quality. Specifically, on November 8, 2011, the inspectors identified that the oil reservoir on the Unit 1 high pressure core spray (HPCS) waterleg pump was empty, with a soiled oil-absorbent pad positioned beneath it. The licensee had previously identified a leak from the reservoir and placed the pad beneath it, but did not enter the problem into the corrective action program (CAP) and did not repair the leak. Upon notification of the condition by the inspectors, the licensee immediately entered this issue into the CAP, verified operability of the HPCS system, restored the oil level, established a special log to monitor the leak, and shortly thereafter replaced the waterleg pump. Additionally, the licensee was conducting an apparent cause evaluation to determine the causes of the occurrence and to develop additional corrective actions. The finding was determined to be more than minor because it was associated with the Mitigating Systems Cornerstone attribute of equipment performance and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The finding was determined to be of very low safety significance because there was no design deficiency, no actual loss of safety function, no single train loss of safety function for greater than the technical specification (TS) allowed outage time, and no risk significance due to external events. This finding has a cross-cutting aspect in the area of problem identification and resolution, corrective action program, for the failure to maintain a low threshold for identifying issues within the CAP commensurate with their safety significance |
