The team identified a Green noncited viola … The team identified a Green noncited violation of Technical Specification 5.4.1.a, which states, in part, Written procedures shall be established, implemented, and maintained, covering the procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A.6.w, Acts of Nature (e.g., tornado, flood, dam failure, earthquakes). Specifically, prior to April 4, 2012, the licensee failed to maintain Procedure 7.0.11, Flood Control Barriers, Revision 24, to ensure the materials required to construct flood protection barriers were correctly listed and inventoried, to effectively protect personnel and equipment doors around the perimeter of the facility. This finding was entered into the licensee\'s corrective action program as Condition Report CR-CNS-2012-01920. The team determined that the failure to maintain Cooper Nuclear Station Operations Procedure 7.0.11, Flood Control Barriers, Revision 24, with an adequate inventory of required materials listed in the procedure, was a performance deficiency. This finding was more than minor because it was associated with the procedure quality attribute of the Mitigating Systems Cornerstone, and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. In accordance with NRC Inspection Manual Chapter 0609, Attachment 4, Phase 1 - Initial Screening and Characterization of Findings, the team determined that the finding was potentially risk significant due to a seismic, flooding, or severe weather initiating event and a Phase 3 analysis was required. A Region IV Senior Reactor Analyst performed a Phase 3 significance determination using NRC Inspection Manual Chapter 0609, Appendix M, Significance Determination Process Using Qualitative Criteria. In accordance with Appendix M, the Senior Reactor Analyst determined that although it is not certain that the licensee could erect all of the flood barriers within 72 hours, it is likely that they could finish barriers to the emergency diesel generators and emergency core cooling systems in time to piOvide vital power and injection capabilities within the time required. Also, it is likely that extraordinary efforts could be taken to complete the barriers if the licensee was falling behind their time line, with knowledge of the timing of the arrival of flood waters. The failure of the Missouri River dams would most likely begin with incipient failure symptoms, providing extra time for the licensee to stage and prepare for the erection of barriers. Therefore, the issue was determined to have very low safety significance (Green). This finding was determined to have a crosscutting aspect in the area of problem identification and resolution associated with the corrective action program component because the licensee failed to take appropriate corrective actions to address safety issues and adverse trends in a timely manner, commensurate with their safety significance and complexity. their safety significance and complexity.
