NRC CAL – NOV (White)

On October 20, 2014, the NRC issued a Notice of Violation associated with a White Significance Determination Process finding to Dominion Nuclear Connecticut, Inc. for a violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, involving the failure to identify and correct a significant condition adverse to quality for the Millstone 3 turbine-driven auxiliary feed water (TDAFW) pump. Specifically, in spite of the TDAFW pump experiencing three over speed trips from August 11, 2013 to February 3, 2014, Dominion did not identify that the pump was operating in an adverse configuration. The Adverse configuration was due to the installation of an inappropriate cam follower bearing within the turbine control valve linkage. This discrepant condition rendered the TDAFW pump inoperable for periods of time exceeding the limiting condition for operation specified in the Millstone 3 Technical Specification 3.7.1.2.
