| Title | Inadequate Compensatory Actions to Minimize the Effects of Impaired Fire Protection Equipment on Fire Safe Shutdown |
| Description | An NRC identified Green NCV of Operating License Condition (OLC) 2.F was identified for the licensees failure to ensure that established operating requirements (ORs) for the high pressure fire protection (HPFP) system accounted for affected and credited equipment as determined in the fire hazard analysis (FHA) and safe shutdown (SSD) analysis. The issue was entered into the licensees corrective action program as PER 786848, and implemented Shift Orders FPU-13-018 and 13-071 which required the establishment of fire watches for the affected areas. The licensees failure to ensure that established ORs for the HPFP water supply system were supported by the FHA and SSD analysis was a performance deficiency. The performance deficiency was more than minor because it was associated with the protection against external events (fire) attribute of the Mitigating Systems Cornerstone and it adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The significance of this finding was determined to be of very low safety significance (Green) because the affected fixed fire suppression systems would be able to suppress a fire such that no additional equipment important to safety would be affected by a fire. The inspectors determined that no cross cutting aspect was applicable to this performance deficiency because this finding was not indicative of current licensee performance. |
