| Title | Licensee-Identified Violation |
| Description | Title 10 CFR 50.65(a)(1) requires, in part, that holders of an operating license shall monitor the performance or condition of systems, structures, and components within the scope of the rule against licensee-established goals in a manner sufficient to provide reasonable assurance that such systems, structures, and components are capable of fulfilling their intended safety functions. Title 10 CFR 50.65(a)(2) requires, in part, that monitoring specified in paragraph (a)(1) is not required where it has been demonstrated the performance or condition of a system, structure, and component is being effectively controlled through appropriate preventive maintenance, such that the system, structure, and component remains capable of performing its intended function. Contrary to the above, from May 13, 2013, to February 28, 2014, the licensee failed to demonstrate that the performance of the remote shutdown system was being effectively controlled through appropriate preventive maintenance. Specifically, station personnel failed to appropriately evaluate repetitive component failures of Gould J11 relays across system boundaries, resulting in the remote shutdown system exceeding the functional failure criteria without implementing appropriate preventive maintenance to improve system performance. The licensee entered this deficiency into the corrective action program as Condition Report CR-RBS-2014-01006. The finding was more than minor since violations of 10 CFR 50.65(a)(2) necessarily involve degraded system performance which, if left uncorrected, could become a more significant safety concern. This finding has very low safety significance (Green) because the finding did not lead to an actual loss of safety function of the system or cause a component to be inoperable, nor did it screen as potentially risk-significant due to a seismic, flooding, or severe weather initiating event. |
