The NRC identified a Green NCV of 10 CFR 5 … The NRC identified a Green NCV of 10 CFR 50 Appendix B, Criterion XV for failing to properly control nonconforming components resulting in the installation of a 4160 volt breaker for the Unit 1 1C CCW pump with a stop bolt gap dimension not meeting vendor and station maintenance acceptance criteria. This finding has been entered into the licensees CAP as CRs 2007108654 and 2008101720. Failure to control components not conforming to requirements in order to prevent their inadvertent use or installation in safety-related applications is a performance deficiency. The NRC determined this finding was more than minor because it was associated with the equipment performance attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective. Specifically, installation of a breaker not meeting vendor or station acceptance criteria challenged the reliability of the 1C CCW pump. Because the finding did not result in a loss of operability or safety function and the finding did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event, the NRC concluded the finding was of very low safety significance (Green). A human performance cross-cutting aspect was identified regarding effectively communicating expectations for procedural compliance and personnel following procedures (H4(b))and personnel following procedures (H4(b)) +
