| Title | Failure to Take Corrective Actions to Address External Flooding Procedure Deficiencies |
| Description | The inspectors identified a finding of very low safety significance and associated non-citied violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Actions, in that from March 13, 2013 until February 14, 2014, the licensee failed to assure that for a significant condition adverse to quality (SQAC), the cause of the condition was determined and corrective actions were taken to preclude repetition. Specifically, the licensees corrective actions failed to preclude repetition of an SQAC where Procedure PC 80 Part 7, Lake Water Level Determination, as implemented, would not protect safety-related equipment in the turbine building or Circulating Water Pump House (CWPH). After the licensee had taken corrective actions to improve the wave barrier procedure in response to an NRC-identified NOV, PC 80 Part 7 and other flood protection implementing procedures specified inadequate timelines to ensure wave run-up flood barriers would be installed prior to the lake level at which wave run-up could impact the site. Corrective actions for this issue included changing the affected procedures to install the wave barriers at a lower lake level, changing the lake level determination surveillance from monthly to weekly, and reducing the allowed installation time for the barriers from 3 weeks to 1 week. The performance deficiency was screened against the Reactor Oversight Process per the guidance of lMC 0612, Appendix B, and determined to be more than minor because the finding 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). Specifically, the licensees failure to correct procedural deficiencies associated with flood barrier construction timelines, could challenge the timely installation of the barriers, which could impact the ability of mitigating systems to respond during an external flooding event. The inspectors evaluated the finding using IMC 0609, Attachment 0609.04, Tables 2 and 3, and Appendix A. Based on a review of Appendix A, Exhibit 2, Item 4.B, the inspectors determined that this issue screened as having very low safety significance (Green). This finding has a cross-cutting aspect in the area of problem identification and resolution, because the licensee failed to thoroughly evaluate issues to ensure that resolutions address causes and extent of conditions commensurate with their safety significance. |
