| Title | Failure to Perform an Operability Determination for Partially Submerged EDG Cables |
| Description | The inspectors identified a finding of very low safety significance with an associated non-cited violation of 10 CFR 50, Appendix B, Criterion V, "Instructions, Procedures, an
Drawings," for the licensees failure to complete an operability determination as required b Procedures MQA-11, "Condition Assessment Resolution Document," Revision 38, and ODE-11, "CARD Operability/Reportability Determination Expectations," Revision 15. Specifically, the licensee failed to perform an operability determination for Condition Assessment Resolution Document 14-27704 that identified water on September 30, 2014, in a manhole partially submerging safety-related Division 1 emergency diesel generator (EDG) cables. The licensee subsequently completed an operability evaluation that supported continued operability of the safety-related EDG cables. The finding was of more than minor safety significance because, if left uncorrected, it would have the potential to lead to a more significant safety concern. Specifically, the failure to perform an operability determination for submerged safety-related EDG cables could potentially lead to one or more failed cables and inoperable onsite emergency power sources without the licensees knowledge. The finding was a licensee performance deficiency of very low safety significance because it: (1) was not a deficiency affecting the design or qualification of a mitigating Structure, System, and Component (SSC), (2) did not represent a loss of system and/or function, (3) did not represent an actual loss of function of at least a single train for greater than its Technical Specification (TS) allowed outage time OR two separate safety systems out-of-service for greater than its TS allowed outage time, and (4) did not represent an actual loss of function of one or more non-TS trains or equipment designated as high safety significant in accordance with the licensees Maintenance Rule Program for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. The inspectors determined thi finding affected the cross-cutting area of problem identification and resolution and the evaluation aspect (P.2) due to the licensees failure to thoroughly evaluate the issue t ensure that resolutions address causes and extent of conditions commensurate with thei safety significance. |
