| Title | |
| Description | On April 7, 2008, the inspectors identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, due to an approximately 10-15 gpm leak on the Emergency Diesel Generator B lubricating oil heat exchanger cover plate. Water hammer caused part of the cover plate gasket to be ejected from the heat exchanger and created the leak. The inspectors found that the work order to assemble the heat exchanger was inadequate. Wolf Creek evaluations did not identify that vendor manual steps were not incorporated into the installation work order which led to loose cover plate nuts which caused the leak. Wolf Creek subsequently wrote Condition Report 2008-004982. Wolf Creeks failure to ensure that the configuration of both emergency diesel generator lube oil heat exchangers was per plant design was considered a performance deficiency. Using Manual Chapter 0609.04, Phase 1 - Initial Screening and Characterization of Findings, this finding was determined be of very low safety significance. Specifically, the deficiency did not result in the loss of operability or functionality and did not represent a risk significant external event such as flooding. The inspectors determined that the finding has a human performance crosscutting aspect in the area associated with resources. Specifically, Wolf Creek did not ensure that Work Order 08-305289-000 was adequate to ensure nuclear safety by including vendor instructions or acceptance criteria for both emergency diesel generator lube oil heat exchanger cover plates H.2(c) (Section 1R19). |
