Title | Failure to Track ApplicableTechnical Specification Action Statement for Residual Heat Removal System |
Description | The NRC identified a NCV of technical specification (TS) 5.7.1.1.a, Procedures, for the licensees failure to implement OPDP-8, Operability Determinations and Limiting Conditions for Operations (LCO) tracking. Specifically, the licensee failed to track the applicability of action statement A of TS LCO 3.5.2.A, emergency core cooling systems, during planned testing. The licensee entered this issue into their corrective action program as CR 1010269. The performance deficiency was more than minor because, if left uncorrected, it would have had the potential to lead to a more significant safety concern in that, the failure to track an applicable technical specification action statement could lead to plant operations outside of TS analyzed conditions. The inspectors determined that this finding was of very low safety significance (Green) because the finding did not represent an actual loss of function of a single train for greater than its TS allowed outage time and did not represent an actual loss of function of one or more non-technical specification equipment for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. The performance deficiency had a cross-cutting aspect of Avoid Complacency in the area of Human Performance because licensee personnel were complacent and failed to question long held assumptions about the ability of the valves to fail to their safe position under all design basis conditions. |
