NRC CAL – NOV (White)

On August 17, 2007, a Notice of Violation was issued for a violation associated with a White Significance Determination Finding involving a violation 10 CFR Part 50, Appendix B, Criterion XVI. The licensee failed to establish measures to promptly identify and correct a significant condition adverse to quality (SCAQ) and failed to assure that the cause of a SCAQ was determined and corrective action taken to preclude repetition. Specifically, the licensee's inadequate procedural guidance for evaluating the suitability of parts used in safety related applications presented an opportunity in which the licensee failed to promptly identify a defective voltage regulator circuit board used in Emergency Diesel Generator (EDG) 2 prior to its installation. Following installation of the defective EDG 2 voltage regulator circuit board, the licensee failed to determine the cause of two high voltage conditions, and failed to take corrective action to preclude repetition. As a result, an additional high voltage condition occurred resulting in a failure of EDG 2.
