| Title | Failure to Promptly Identify and Correct a Condition Adverse to Quality with the \'B\' MSIV |
| Description | The inspectors identified a Green NCV of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, for Ginna\'s failure to: promptly identify and correct a condition adverse to quality. Specifically, Ginna did not promptly identify and correct a deenergized control power channel for the \'B\' main steam isolation valve (MSIV) caused by a loose fuse clip. Corrective actions included forming an incident response team (IRT), visually inspecting all fuse clips where the plastic fuse blanks were used since April 2011, identifying potentially loose fuse dips, repairing any loose clips identified, ensuring operators know how to properly use the plastic fuse blanks to prevent fuse clip damage. and requiring electrical maintenance support to verify the integrity of the fuse clip/fuse connection after removal of the plastic fuse blank and reinsertion of the fuse. This finding is more than minor because the performance deficiency is associated with the Mitigating Systems cornerstone attribute of equipment performance (reliability, availability) and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (Le. core damage). The inspectors determined this finding was not a design or qualification deficiency, did not involve an actual loss of safety function for greater than its technical specification (TS) allowed outage time, and did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. Therefore, the inspectors determined the finding to be of very low safety significance. The finding has a cross-cutting aspect in the area of Problem Identification and Resolution (PI&R), Corrective Action Program (CAP), because Ginna did not thoroughly evaluate the problem such that the resolution addressed the cause and extent of condition. Specifically, Ginna did not adequately evaluate the loss of position indicating lights on the \'B\' MSIV to ensure that the correct cause was identified. |
