| Title | Failure to Accomplish Station Procedures for Severe Weather |
| Description | The NRC identified a Green finding (FIN) for the failure of the licensee to accomplish operations administrative procedure, OAP-109.1, Guidelines for Severe Weather, Rev. 4H, for adequate control of sandbags used for ground level plant building access door protection during a permissible maximum precipitation (PMP) or other adverse rainfall events. The licensee entered the issue in their corrective action program as condition reports, CR-17-05632 and CR-17-05783.The inspectors reviewed IMC 0612, Appendix B, Issue Screening, and determined the performance deficiency (PD) was more than minor and therefore a finding because the PD affected the Mitigating Systems Cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences and the respective attribute of protection against external factors (i.e., flooding). Specifically, without the sandbag container sealed, the licensee would not be able to expedite the sandbags into the protected area (PA), and degradation of the sandbags would have prevented use as specified. The inspectors reviewed IMC 0609, Attachment 4, Appendix A, and Exhibit 4, for the significance determination, and determined the finding was of very low safety significance, or Green, because the finding does not involve the total loss of any safety function, identified by the licensee through a probabilistic risk analysis (PRA), individual plant examination of external events (IPEEE), or similar analysis, that contributes to external event initiated core damage accident sequences (i.e., flooding). Specifically, the time afforded the licensee via weather forecasting would have allowed other measures to mitigate ingress of flood waters into plant areas.The inspectors reviewed IMC 0310, Aspects Within Cross-Cutting Areas, and determined the cause of the finding involved the area of human performance and the aspect of H.1:Resources: Leaders ensure that personnel, equipment, procedures, and other resources are available and adequate to support nuclear safety, because the licensee did not ensure that resources were available to check the security seals on the containers and the licensee did not ensure the sandbags were capable of meeting its intended function. |
