| Title | Failure to Ensure UFSAR described Flood Protection Measures in Place |
| Description | An NRC-Identified finding was identified for the licensees failure to ensure the Oconee UFSAR-described Auxiliary Building (AB) flood protection measures were maintained. Penetrations below the design basis 796.5 foot mean sea level (msl) elevation were not included in a surveillance program to verify below-grade penetrations would not allow flooding of the AB. The performance deficiency was more than minor because if left uncorrected, it could lead to a more significant safety concern, in that, other onsite activities such as excavation work exterior to the AB walls could provide a pathway for flood waters to enter the AB through the uncontrolled penetrations causing the loss of accident mitigation systems. The finding was of very low safety significance because an actual loss of operability or functionality did not occur. The cause of the finding was directly related to the appropriate corrective actions aspect of the Corrective Action Program component in the area of Problem Identification and Resolution because the licensee failed to correct the O-310 K series to identify that all external AB walls as flood barriers. |
