NRC CAL – NOV (White)

On October 27, 2006, a Notice of Violation was issued for a violation associated with a WHITE significance determination process finding involving inadequate design control during the establishment of the over-current trip setting for an electrical circuit breaker that supplies power to the support systems for the 1A emergency diesel generator (EDG). The violation was cited against 10 CFR Part 50, Appendix B, Criterion III, "Design Control," because the licensee failed to ensure that design control measures provided for verifying or checking the adequacy of the design when Calvert Cliffs modified the on-site electrical distribution design by installing a new 1A EDG in 1996.
