An NRC-identified NCV of 10 CFR Part 50 Ap … An NRC-identified NCV of 10 CFR Part 50 Appendix B, Criterion XI, Test Control was identified for preconditioning of the Turbine Building Plant Service Water (PSW) Isolation Valves. A maintenance work order stoked the valves several times prior to performing the documented stroke time testing. This finding is more than minor because if left uncorrected the finding had the potential to lead to a more significant safety concern in that other safety-related valve performance deficiencies could have been masked. In accordance with NRC Inspection Manual Chapter 0609, Significant Determination Process, the inspectors performed a Phase 1 analysis and determined the finding was of very low safety significance (Green) because the finding did not result in a loss of safety function. The finding has an associated cross-cutting aspect in the area of Problem Identification & Resolution. Specifically as it relates to implementation of Operating Experience (OE) because the licensee has reviewed prior OE describing unacceptable preconditioning, but failed to recognize preconditioning and prevent it prior to performing work associated with the maintenance work order (P.2.b)ciated with the maintenance work order (P.2.b) +
