Title | Failure to Establish Procedures to Respond to Probable Maximum Precipitation |
Description | A finding of very low safety significance and an associated non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified by the inspectors for the licensees failure to establish an abnormal operating procedure (AOP) to respond to a flooding event and for failure to establish procedures for control and maintenance of external flooding design features for the probable maximum precipitation event as described in the FSAR. The issue was entered into the licensees CAP as AR01856322 for evaluation and development of corrective actions. The finding was determined to be more than minor in accordance with IMC 0612, Appendix B, because it was associated with the Mitigating Systems Cornerstone attributes of Protection Against External Factors (Flood Hazard) and Procedure Quality, and adversely affected 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). The inspectors evaluated the finding using IMC 0609, Appendix A, Exhibit 2, for the Mitigating Systems Cornerstone, and determined the finding to be of very low safety significance. This finding has a cross-cutting aspect in the area of human performance, resources, because the licensee failed to maintain long term plant safety by maintenance of the external flooding design features (H.2(a)). Specifically, in the recent past, the licensee inappropriately cancelled the preventive maintenance associated with the ditches and storm drains following the completion of the drainage system study in June 2010. |
