An inspector identified finding of very lo … An inspector identified finding of very low safety significance and a Non-Cited Violation of 10 CFR Part 50, Appendix B, Criterion XI, due to the licensees failure to ensure Check Valve SI-9-5 was tested under suitable environmental conditions. Specifically, the licensee preconditioned SI-9-5 prior to testing by increasing reactor pressure and tapping on the valve with a hammer. The inspectors determined that this finding was more than minor because it was associated with the equipment performance attribute of the initiating events cornerstone. The finding affected the cornerstone objective of limiting the frequency of those events that upset plant stability and challenge critical safety functions. The inspectors concluded that the finding was of very low safety significance because it was not a primary system loss of coolant accident or transient initiator. Additionally, the finding did not screen as potentially risk significant due to a fire, seismic, flooding, or severe weather initiating event. The inspectors concluded that this finding affected the corrective action program component of the Problem Identification and Resolution cross-cutting area because the licensee failed to evaluate the cause of the 2008 SI-9-5 valve test failures to ensure that the resolution addressed the cause and extent of condition (P.1(c)). The corrective actions for this issue included restoring the valve to an operable but degraded condition, providing training on preconditioning, providing training on the use and implementation of the operability determination process, and improving the thorough evaluation of equipment related deficiencies.
