NRC CAL – NOV (White)

On January 14, 2010, the NRC issued a Notice of Violation to Entergy Operations, Inc. for a violation of Technical Specification 6.8.1.a, "Procedures and Programs," at Waterford Steam Electric Station Unit 3. The violation, which is associated with a White Significance Determination Process finding, involved the failure to properly follow all procedural steps during replacement of the safety-related Train B 125 Vdc battery in May 2008. Specifically, following replacement of the battery, the licensee did not: (1) adequately torque all of the affected intercell connections, (2) obtain the required quality control inspector verification that all affected connections were properly tightened, (3) ensure that all the necessary intercell resistance checks were performed, and (4) obtain quality control verification that the intercell resistance checks met Technical Specification limits. As a result, an intercell connection on the battery loosened over time and on September 2, 2008, the battery was found to be inoperable during testing.
