| Title | Inadequate Functionality Assessment for Fire Protection System |
| Description | The inspectors identified a non-cited violation (NCV) of Technical Specification (TS) 6. 7.1.a that requires that written procedures be established and implemented, including administrative procedures that define authorities and responsibilities for safe operation. Specifically, NextEra identified a degraded condition in the fire protection system on July 15, 2011, but did not properly or thoroughly evaluate the fire protection system performance as required by NextEra procedure EN-AA-203-1001. As corrective action, NextEra completed an operability evaluation that identified degraded fire protection system performance under certain operating conditions for which NextEra implemented administrative controls that would prevent the degraded performance. The performance deficiency was more than minor because a reasonable doubt of operability existed until further engineering evaluations were completed to demonstrate adequate fire system performance under design basis conditions. The finding affected the Mitigating Systems cornerstone objective to ensure the availability, reliability and capability of systems that respond to initiating events in order to prevent core damage. The issue was evaluated using Appendix F of IMC 0609, Significance Determination Process (SOP), and was determined to be of very low safety significance (Green) because the finding had minimal impact on fire system performance. The finding had a cross cutting aspect in the area of problem identification and resolution, P.1 (c), because NextEra personnel did not adequately implement the operability determination process to ensure that fire system performance was thoroughly evaluated for operability to assure timely and appropriate corrective actions were completed. |
