Title | LICENSEE-IDENTIFIED Violation |
Description | 10 CFR Part 50, Appendix B, Criterion XI, Test Control, requires, in part, that testing is performed under suitable environmental conditions. Suitable environmental conditions include those that are representative of expected standby configuration and the condition in which the equipment would be when required to perform its safety function. Contrary to the above requirement, on October 31, 2008, the licensee failed to assure that testing performed on Valve CV-3821 was performed under suitable environmental conditions. Specifically, the boundary valve leak test for Valves CV-3811, CV-3821, and SW-9 was performed multiple times, due to an unaccounted for temporary modification, prior to obtaining satisfactory test data for Valve CV-3821. This finding was determined to have very low safety significance because: (1) the finding was not a qualification deficiency that resulted in a loss functionality, (2) it did not lead to an actual loss of safety function of the system or train, (3) it did not result in the loss of one or more trains of nontechnical specification equipment, (4) it did not represent an actual loss of safety function of one or more nontechnical specification trains of equipment designated as risk-significant per 10 CFR 50.65 for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and (5) it did not screen as potentially risk-significant due to a seismic, flooding, or severe weather initiating event. This issue was entered into the licensees corrective action program as Condition Reports ANO-1-2008-1618 and ANO-1-2008-1653 |
