The inspectors identified a finding of ver … The inspectors identified a finding of very low safety significance with an associated non-citied violation of 10 CFR 50, Appendix B, Criterion XV, Nonconforming Materials, Parts, or Components, for the failure to prevent nonconforming parts from being used on the emergency diesel generators (EDGs). In 2006, the licensee changed the material used to manufacture delivery valve holders to address cracking of the component. However, the licensee failed to ensure all delivery valve holders were replaced. In 2009 and in 2013, the licensee identified installed delivery valve holders made from the susceptible material. In addition, the licensee determined in 2013 that a manufacturing defect impacted a lot of delivery valve holders. The licensee failed to control the non-conforming components and installed one in an EDG. In both cases, although the licensee found the discrepant parts, the site failed to explore broader programmatic issues with nonconforming material control or shortfalls in the root cause evaluation done to address previous issues with cracking. As corrective actions, the licensee has since replaced all suspect pumps and generated action requests to assess programmatic issues with nonconforming material control. The inspectors determined the finding to be more-than-minor because it adversely affected the Design Control attribute of the Mitigating Systems cornerstone. Specifically, allowing nonconforming parts to be installed on safety-related equipment without proper controls or review adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The issue screened as Green, or very low safety significance, utilizing IMC 0609 Attachment 4, Initial Characterization of Findings. Specifically, per Exhibit 2, the finding was determined to be a deficiency affecting the design or qualification of a mitigating system, structure or component where operability was maintained. The inspectors determined the finding had an associated cross-cutting aspect in the area of Problem Identification and Resolution. Specifically, programmatic issues associated with material control were not identified for resolution by the corrective action program (CAP) (P.1).the corrective action program (CAP) (P.1).
