| Title | Failure to Perform Functionality Assessments for Flood Protection Features |
| Description | An NRC-identified Green finding was identified for the failure of the licensee to follow Procedure OPS-NGGC-1305, Operability Determinations, to perform functionality assessments for degraded or non-conforming flood protection features. Specifically, the licensee failed to perform functionality assessments for flood protection features, including EDG building conduit seals and Unit 2 HPCI sump pump failures. The licensee entered these issues into the CAP as NCRs 613354 and 631442. The inspectors determined the failure to follow Procedure OPS-NGGC-1305, to perform functionality assessments for degraded or non-conforming flood protection features, was a performance deficiency. The finding is more than minor because it is associated with the protection against external factors (i.e., flood hazard) attribute of the Mitigating Systems Cornerstone and adversely affects the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). Specifically, the failure to perform functionality assessments for degraded or non-conforming flood protection features could have resulted in a flood pathway into the HPCI room and EDG building during a PMH. Using IMC 0609, Appendix A, issued June 9, 2012, The SDP for Findings At-Power, the inspectors determined the finding screened to Green because the resulting individual functional assessments did not involve the total loss of any safety function, identified by the licensee through a PRA, IPEEE, or similar analysis, that contributes to external event initiated core damage accident sequences (i.e., initiated by a seismic, flooding, or severe weather event). The finding has a cross-cutting aspect in the area of human performance associated with the procedure adherence attribute because the licensee did not follow processes, procedures, and work instructions. Specifically, the licensee revised Procedure OPS-NGGC-1305 for performing functionality assessments but did not effectively communicate the new procedural requirements to operations personnel such that functionality assessments were performed when required. |
