NRC ORDER – NOV (White)

On March 14, 2011, the NRC issued a violation of 10 CFR Part 50, Appendix B, Criterion V, associated with a White Significance Determination Process finding involving the failure to provide appropriate quantitative or qualitative acceptance criteria related to maintenance on the 2A emergency diesel generator. Specifically, on January 17, 2010, a work order package did not contain a final torque verification to ensure that the 2A diesel generator upper lube oil cooler spool piece connections were torqued to the required values. As a result, the spool piece flange connection to the upper lube oil cooler did not meet the minimum torque ranges, and, subsequently, during routine testing on November 17, 2010, the flange connection on the 2A diesel generator upper lube oil cooler failed. Because the 2A diesel generator was inoperable since January 17, 2010, and because the licensee was not aware of the inoperability, the Technical Specification allowed outage time of 14 days was also exceeded.
