| Title | Inadequate Procedures for Inspecting Flood Protection Doors and Performing Functionality Assessments |
| Description | An NRC-identified Green finding for the failure to meet the requirements of licensee procedure PRO-NGGC-0201, NGG Procedure Writers Guide, was identified with two examples. Specifically, the licensee failed to provide an adequate procedure with appropriate acceptance criteria to inspect flood protection doors for leakage and failed to have an adequate procedure to perform functionality assessments which met the requirements specified in Procedure PRO-NGGC-0201. The licensee entered these issues into the corrective action program (CAP) as nuclear condition reports (NCRs) 631303, and 563113 and 580629, respectively. The inspectors determined that the failure of the licensee to provide an adequate procedure to inspect flood protection doors for leakage and to have an adequate procedure which met the requirements of licensee Procedure PRO-NGGC-0201 to perform functionality assessments 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 flood protection door and flood penetration seals were missing or degraded which could have resulted in a flood pathway into the high pressure coolant injection (HPCI) system room and service water building (SWB) 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 individual door and penetration seal degradations did not involve the total loss of any safety function, identified by the licensee through a probabilistic risk assessment (PRA), individual plant examination of external events (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 documentation attribute because the licensee failed to create and maintain complete, accurate and, up-to-date documentation to inspect flood protection doors and perform functionality assessments. |
