| Title | Failure to Demonstrate the Functionality of a Credited Safe Shutdown Component |
| Description | The inspectors identified a finding of very low safety significance and an associated NCV of license condition 4.F for the licensees failure to demonstrate the capabilities of systems needed to perform a design function for Appendix R cold shutdown. Specifically, none of the licensees tests, inspections, or maintenance activities demonstrated that CC-722A, the component cooling water pump suction cross-tie valve, was capable of being opened as required in AOP-10B, Safe to Cold Shutdown in Local Control. The licensee corrective actions included entering the issue into their CA program, declaring CC-722A non-functional, and commencing four-hour fire rounds. The inspectors determined the finding to be more than minor because the failure to demonstrate the capabilities of systems needed to perform a design function for Appendix R safe shutdown was associated with the Mitigating Systems Cornerstone attribute of Protection Against External Events (Fire) and affected the cornerstone objective of preventing undesirable consequences (i.e., core damage). In accordance with IMC 0609, Significance Determination Process, Attachment 0609.04, Initial Characterization of Findings, Table 2, the inspectors determined the finding affected the Mitigating Systems cornerstone. The finding affected the ability to reach and maintain safe shutdown, and the inspectors determined, using Table 3, that it could be evaluated using Appendix F, Fire Protection Significance Determination Process. The inspectors screened the issue to Green under the Phase 1 Screening Question 1.3.1A, because the inspectors determined that the finding would not prevent the reactor from reaching and maintaining hot shutdown. This finding has a cross-cutting aspect of Resolution (P.3), in the area of problem identification and resolution, because the licensee did not take effective corrective actions to address the issue in a timely manner. Specifically, in 2007, the licensee identified that they had not been testing the valve as specified in their Fire Protection Evaluation Report and as of July 2015 had still not corrected it. |
