The inspectors documented a self-revealing … The inspectors documented a self-revealing, non-cited violation of 10 CFR Part 50, Appendix B, Criterion VII, Control of Purchased Material, Equipment and Services for the licensees failure to assure that purchased material conformed to the procurement documents. Specifically, the licensee received, accepted and installed the wrong couplings on the Unit 1 service water pump C resulting in a coupling failure that left the pump inoperable. The licensee rebuilt service water pump C with the correct coupling material. This was documented in Condition Report CR-ANO-1- 2012-0864. The inspectors determined that the failure to assure that purchased material conformed to the purchase order is a performance deficiency because the licensee failed to perform an adequate receipt inspection then accepted and installed the wrong couplings that subsequently failed. The performance deficiency had the potential to affect the Initiating Events or Mitigating Systems Cornerstones so a regional senior reactor analyst was contacted for assistance. The senior reactor analyst performed a phase 3 analysis and determined the dominant risk affected the Mitigating Systems cornerstone. The performance deficiency is more than minor because it is associated with the equipment performance attribute of the Mitigating Systems Cornerstone and adversely affects the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences and is therefore a finding. The phase 3 analysis determined the majority of the risk resulted from a loss of AC Bus A3 combined with a loss of the turbine-driven emergency feedwater pump. The finding was determined to be of very low safety significance (Green). The finding was determined not to have a cross-cutting aspect because the performance deficiency occurred in 2009 and is not indicative of current plant performance.t indicative of current plant performance. +
