| Title | Failure to Properly Manage the Functionality of the River Sluice Gates |
| Description | The team identified a finding exemplified by multiple violations for the failure to manage the functionality of the river sluice gates. Specifically, the licensees preventive maintenance program requirements were not appropriately implemented for a period of 6 months and as a result, the functionality of the river sluice gates was improperly maintained. The examples were: 1. A licensee identified violation of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures and Drawings, for the failure to perform preventive maintenance required to demonstrate the functionality of the river sluice gates. An NRC identified violation of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures and Drawings, for the failure to accomplish activities affecting quality in accordance with prescribed instructions when in September 2012, the licensee failed to test the C and D river sluice gates in accordance with station procedure SAO-12-001, to properly maintain functionality of the river sluice gates. 2. An NRC identified violation of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures and Drawings, for the failure to accomplish activities affecting quality in accordance with prescribed instructions when the licensee failed to test all six gates in October 2012, to maintain functionality of the river sluice gates in accordance with station procedure SAO-12-001. 3. An NRC identified violation of 10 CFR 50, Appendix B, Criterion XVI, Corrective Actions, for the licensees failure to properly identify and timely enter conditions adverse to quality into the Corrective Action Program following multiple failures of the river sluice gates. 4. An NRC identified violation of 10 CFR 50.65, Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants, for the licensees failure to demonstrate effective control of performance of the circulating water system river sluice gates and failure to place the system in (a)(1) when system performance deteriorated. 5. An NRC identified violation of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures and Drawings, for the failure to accomplish activities affecting quality in accordance with prescribed instructions when the licensee failed to make the appropriate functionality assessment when the circulating water river sluice gates failed to close during the August 2012 monthly test. The licensee entered these issues into their Corrective Action Program under various CRs described in the body of this report. The team concluded that the failure to manage the functionality of the sluice gates was a performance deficiency that warranted further evaluation. Specifically, the licensees preventive maintenance program requirements were not appropriately implemented for a period of 6 months and as a result, the functionality of the sluice gates was improperly maintained. Using the guidance in IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Screening, the inspectors determined this finding affected the Mitigating Systems cornerstone. The finding is greater than minor because it is associated with both of the Mitigating Systems Cornerstone attributes of Equipment Performance and Protection Against External Factors and, it adversely affects the associated cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The significance of this finding is bounded by the significance of a related Yellow finding regarding the ability to mitigate an external flooding event (Inspection Report 05000285/2010008). The inspectors determined the finding had a cross-cutting aspect in the area of problem identification and resolution because the licensee did not take appropriate corrective action to address safety issues and adverse trends in a timely manner, commensurate with their safety significance and complexity. |
