| Title | Failure to perform appropriate post maintenance test on 2A EDG |
| Description | A self-revealing Green NCV of Hatch Unit 2 Technical Specification 5.4. Procedures, was identified on March 9, 2013, when the licensee failed to perform post maintenance activities appropriate to the circumstances to verify 2A emergency diesel generator (EDG) lube oil heat exchanger integrity at normal plant service water operating pressure prior to declaring the 2A EDG operable. This violation has been entered into the licensees corrective action program as condition report (CR) 603356. The licensee replaced the gasket on the lube oil heat exchanger waterbox flange and on March 10, 2013, 2A EDG was returned to operable status. Failure to perform post maintenance activities appropriate to the circumstances to verify 2A EDG lube oil heat exchanger integrity at normal service water operating pressure prior to declaring the 2A EDG operable was a performance deficiency. This performance deficiency was more-than-minor because it adversely affected the equipment performance attribute of the mitigating systems cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the 2A EDG was rendered unavailable after leakage developed at plant service water pressure. The inspectors evaluated the finding in accordance with IMC 0609, Attachment 4, Initial Characterization of Findings , June 19, 2012, using Table 2, Cornerstones Affected by Degradation Condition or Programmatic Weakness. The finding affected the mitigating systems cornerstone and required further evaluation using IMC 0609 Appendix A, The Significance Determination Process (SDP) for Findings At-Power, June 19, 2012. Based on Exhibit 2, Mitigating Systems Screening Questions, Section A, Mitigating SSCs and Functionality , all four questions were answered no and thus this finding screened as Green. The inspectors determined this finding had a cross cutting aspect in the human performance area associated with resources - training and sufficiently qualified personnel because senior reactor operators did not ensure that the post maintenance test conditions were at maximum system operating pressure as required by procedure. |
