The inspectors identified a non-cited viol … The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XI, Test Controls, for the licensees unevaluated preconditioning of core spray motor operated valves prior to performing as-found inservice stroke time testing. The licensee entered this deficiency into their corrective action program for resolution as CR-CNS-2012-01070. The licensees unevaluated preconditioning of core spray motor operated valves prior to performing as-found inservice stroke time testing was a performance deficiency. The performance deficiency was determined to be more than minor because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone, and affected the associated cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, unevaluated preconditioning of valves could mask their actual as-found conditions and result in an inability to verify their operability, as well as, make it difficult to determine whether the valves would perform their intended safety function during an event. The inspectors evaluated the finding using Manual Chapter 0609.04 Phase 1 Initial Screening and Characterization of Findings. The inspectors determined that the finding is of very low safety significance (Green) because the finding was confirmed not to result in a loss of operability or functionality of the core spray system. The finding has a cross-cutting aspect in the area of human performance associated with resources component because the licensee did not provide complete, accurate, and up-to-date procedures and work packages to prevent precondition of valves prior to testingnt precondition of valves prior to testing +
