| Title | Failure to Comply with Technical Specification 3.0.3 |
| Description | The NRC identified a non-cited violation of Technical Specification (TS) 3.0.3 for the licensees failure to take the required actions to shut down the plant in a timely manner. The licensees failure to perform an adequate operability evaluation in accordance with the requirements of EN-AA-203-1001, Operability Determinations / Functional Assessments, was a performance deficiency. Specifically, the licensee failed to identify in an Immediate Operability Determination that through-wall leakage on the ASME Class 1 pipe riser for vent valve V3811 rendered both Emergency Core Coolig Systems (ECCS) subsystems inoperable, requiring entry into TS LCO 3.0.3 and performance of the applicable action statements. The licensee entered this into their corrective action program as AR 02021204. The performance deficiency was more than minor because it was associated with the equipment reliability attribute of the mitigating systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors determined the finding was associated with the mitigating systems cornerstone and required a detailed risk evaluation because the finding represented a loss of function on the high pressure safety injection system. A detailed risk evaluation determined the significance of the finding was Green. The inspectors determined the finding was related to the crosscutting aspect of Evaluation (P.2) of the Problem Identification and Resolution area because the licensees failure to thoroughly evaluate the issue commensurate with its safety significance led to the licensee failing to perform an appropriate operability evaluation. |
