Finding

Title

Failure to Follow Procedure Results in Inoperable SI Accumulator

Description

A self-revealing NCV of technical specification (TS) 5.4.1 was identified because the unit 2 B safety injection (SI) accumulator was made inoperable when FENOC operators did not follow procedural requirements to align nitrogen to the accumulator. Specifically, the operators did not align the nitrogen header to the accumulator prior to opening the valve to repressurize the accumulator. The inspectors noted that this resulted in the accumulator pressure falling below the TS pressure limit which required FENOC to declare the accumulator inoperable. FENOCs corrective actions included immediately realigning the system, restoring accumulator pressure and entering the issue into their corrective action program, CR 2014-09260. The performance deficiency is more than minor because it is associated with the configuration control attribute of the mitigating systems cornerstone and adversely affected the cornerstone objective of ensuring the availability, reliability and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, FENOC did not have reasonable assurance that the nitrogen pressure in the B SI accumulator was sufficient to ensure injection into the core during an accident due to the misalignment of the nitrogen header. This finding is of very low safety significance (Green) because the performance deficiency was not a design or qualification deficiency, did not involve an actual loss of safety function, did not represent actual loss of a safety function of a single train for greater than its technical specification allowed outage time, and did not screen as potentially risk-significant due to a seismic, flooding, or severe weather initiating event. This finding has a cross-cutting aspect in the area of Human Performance, Avoid Complacency, because FENOC operators did not recognize the possibility of mistakes and did not implement appropriate error reduction tools while attempting to re-pressurize the B SI accumulator.
