| Title | Failure to Promptly Replace Keep Fill Pumps |
| Description | The team identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, which occurred when the licensee failed to promptly correct an identified condition adverse to quality. Specifically, in 1998, the licensee identified an inadequate design of the in keep fill pumps for the reactor core isolation cooling system and emergency core cooling system that resulted in repetitive unexpected failures of the pumps. Corrective actions for this condition adverse to quality had been repeatedly deferred since the condition was originally identified; no effective corrective actions had been taken as of September 2009. The licensee entered this issue into their corrective action program as Action Request/Condition Report 204768. This performance deficiency was more than minor because it was associated with the equipment performance attribute of the mitigating systems cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609.04, Phase 1 Initial Screening and Characterization of Findings, the team determined that this performance deficiency was of very low safety significance because it did not represent a loss of system safety function, did not represent the actual loss of safety function of a single train for greater than its technical specification allowed outage time, and did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. The team determined that this finding had a crosscutting aspect in the resources component of the human performance area because the licensee failed to ensure that resources were available to minimize long-standing equipment issues H.2(a). |
