The inspectors identified a Green finding … The inspectors identified a Green finding and an associated NCV of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, when licensee personnel failed to promptly correct a previously identified NCV regarding the lack of analysis for water hammer loads on the Recycle Holdup Tank (RHUT) inlet piping induced by Residual Heat Removal (RHR) system relief valve discharges. Specifically, the licensee failed to complete the necessary piping analysis to address potential water hammer effects since the issue was initially identified in June 2007 and documented as a NCV in February 2009. The licensee entered this issue into the CAP as IR 1117296 and planned to accelerate the completion schedule for the analysis. The finding was more than minor because it was associated with the design control attribute of the Barrier Integrity Cornerstone and affected the cornerstone objective of maintaining the radiological barrier function of the containment. The finding was of very low safety significance because it did not represent an actual open pathway from containment. This finding has a cross-cutting aspect in the area of Human Performance for Resources (H.2(a)) because the licensee failed to maintain longterm plant safety by completing the necessary piping load calculations in a timely manner.ping load calculations in a timely manner. +
