| Title | |
| Description | The inspectors identified a Green NCV of 10 CFR 50.65(b)(2), Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants, because the licensee failed to scope in all the Chemical Volume and Control (CVCS) instruments used in plant Emergency Operating Procedures (EOPs). Specifically, the CVCS instrument loops for FI-110, Boric Acid Bypass Flow, FI-122A, Charging Flow and LI-115, volume control tank (VCT) Level, were not included in the maintenance monitoring program. Subsequent review by the licensee identified one additional functional failure that was previously unrecognized. The licensee entered the issue into their corrective action program (CAP) as Nuclear Condition Report (NCR) 574956. The licensee corrective actions included adding the associated instruments loops to the maintenance rule program and revising the performance monitoring criteria. The inspectors determined that the failure to scope in all the CVCS instruments, used in EOPS, into the maintenance rule program was a performance deficiency. The finding was more than minor because if left uncorrected, the performance deficiency would have had the potential to lead to a more significant safety concern. Specifically, the failure to scope in all CVCS instruments into the maintenance rule program could affect the maintenance rule programs ability to effectively monitor the performance of CVCS equipment and the accomplishment of EOPs. This finding was considered to have very low safety significance (Green) because the finding did not cause a loss of mitigation equipment functions and did not represent an actual loss of function of one or more non-Tech Spec Trains of 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 finding does not have a cross-cutting aspect since the failure to scope this equipment into the maintenance rule program was not recognized during the initial maintenance rule scoping activities and as a result, is not indicative of current performance. |
