| Title | Failure to Accomplish Procedure to Determine Cause and Correct Failures of Reactor Building Spray System Relief Valve |
| Description | An NRC-identified NCV of 10 CFR 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," was identified for the licensees failure to accomplish a general test procedure, GTP-302, requirement to determine the cause and correct the conditions leading to two failures of reactor building spray system relief valve, XVR03026-SP. The licensee entered the problem into their corrective action program (CAP) as condition report (CR) 14-03079. The licensees failure to accomplish GTP-302 to determine and correct the cause of failures occurring in 2006 and 2012 was a performance deficiency (PD) which was within their ability to foresee and correct based on the available vendor documentation. The inspectors reviewed IMC 0612, Power Reactor Inspection Reports, Appendix B, and determined the PD was more than minor and therefore a finding, because it affected the Barrier Integrity cornerstone objective to provide reasonable assurance that physical design barriers such as containment protect the public from radionuclide releases caused by accidents or events and the respective attribute of human performance because the availability and reliability of XVR03026-SP was not ensured by a failure to accomplish procedure requirements to determine the cause of two previous failures and correct. The inspectors evaluated the finding in accordance with NRC IMC 0609, Significant Determination Process, attachment 4 and appendix A, and determined that the finding was of very low safety significance, Green, because it did not represent an actual physical open pathway in containment. The inspectors reviewed IMC0310, Aspects Within the Cross-cutting Areas, and determined the cause of the finding involved the cross-cutting area of problem identification and resolution and the respective aspect of complete and thorough evaluation, P.2, because the licensee failed to determine the cause of the relief valve failures for adequate corrective actions. |
