| Title | Hardened grease prevents 1RHRSW pump breaker operation |
| Description | Green. A self-revealing, Green, non-cited violation (NCV) of Hatch Unit 1 Technical Specification 5.4 Procedures, was identified when procedures to rejuvenate grease in the 1C' residual heat removal service water (RHRSW) Pump breaker were not implemented resulting in failure of the pump to start. The violation was entered into the licensees corrective action program as condition report (CR) 10263236 and the breaker was replaced to restore compliance. Failure to rejuvenate the lubricating grease on 4kv DHPVR breakers in accordance with vendor guidance was a performance deficiency. Specifically, the hardened grease prevented the 1C RHRSW pump breaker from closing resulting in the inoperability of the 1C RHRSW pump. The performance deficiency was associated with the Mitigating Systems cornerstone and was more than minor because it adversely affected the cornerstone objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors screened this finding using IMC 0609, Appendix A, The Significant Determination Process (SDP) For Findings At-Power, dated June 19, 2012. Because all four questions in Section A of Exhibit 2, Mitigating Systems Screening Questions, were answered no, the finding screened as Green. The inspectors determined that this finding did not have an associated cross cutting aspect because this finding is not reflective of current licensee performance. |
