The inspectors identified a finding of ver … The inspectors identified a finding of very low safety significance and associated non-cited violation of 10 CFR Part 50, Appendix B, Criterion XI, Test Control, for the failure to ensure adequate test instrumentation was available and used during the performance of periodic venting. This finding was entered into the licensees corrective action program and the licensee will revise the affected procedures to require the use of a timepiece. The performance deficiency was determined to be more than minor because it was associated with the Mitigating Systems cornerstone attribute of Procedure Quality: Maintenance and Testing Procedures. Specifically, by not using adequate test instrumentation to measure the time gas was vented, the licensee introduced further uncertainty to an already inaccurate method. The finding screened as having very low safety significance because the finding involved a design or qualification deficiency that did not result in a loss of operability. Specifically, review of the licensees corrective action program documents for resolution of Generic Letter 2008-01 determined that voids had been identified following system restoration (initial fill and vent) while the system was inoperable, and voids identified when the system was online had been significantly below the calculated acceptance criteria. This finding had a cross-cutting aspect in the area of Problem Identification and Resolution, Operating Experience, because the licensee did not thoroughly evaluate relevant external operating experience. Specifically, the licensees evaluation of Nuclear Energy Institute 09-10, Revision 0, failed to identify the importance of having adequate venting time information when quantifying vented voids.information when quantifying vented voids. +
