| Title | Failure to Identify and Correct a Condition Adverse to Quality |
| Description | A self revealing, Green NCV was indentified for FENOC violating 10 CFR 50, Appendix B, Criterion XVI Corrective Action, for failure to identify and correct a condition adverse to quality on the Controller Driver printed circuit board (NCD board) for the controller for 2CHSFCV160. Specifically, FENOC failed to identify that an NCD board was installed on the controller for 2CHS-FCV160 that was potentially impacted by defects identified in Westinghouse Technical Bulletin TB-08-06 and take corrective actions. The inspectors determined that failing to identify and correct a condition adverse to quality on the NCD board for the controller for 2CHS-FCV160 was a performance deficiency within FENOCs ability to foresee and correct which contributed to over-pressurization of the reactor coolant system (RCS) during solid plant operations. The finding is more than minor because it is associated with the equipment performance attribute of the initiating events cornerstone and adversely impacted the cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown. Specifically, the failure to ensure the availability and reliability of 2CHS-FCV160 led to over-pressurization of the reactor coolant system. The inspectors evaluated the finding using PWR Refueling Operation: RCS level > 23 or PWR Shutdown Operation with Time to Boil > 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> and Inventory in the Pressurizer Checklist 4 of Attachment 1 to Appendix G of IMC 0609. Because no loss of control occurred and no checklist attributes were adversely impacted, a Phase 2 quantitative assessment was not required. Therefore, the inspectors determined the finding to be of very low safety significance. There is no cross-cutting aspect associated with this finding because the performance deficiency is not reflective of FENOCs current performance. |
