- **Category:** Reactor Licensees

## Description

On April 17, 2014, the NRC issued a Notice of Violation to Constellation Energy Nuclear Group, LLC (CENG) for a violation of Title 10 of the Code of Federal Regulations, Part 50, Appendix B, Criterion XVI, "Corrective Action," associated with a White Significance Determination Process finding involving CENG's failure to assure prompt identification and correction of conditions adverse to quality. Specifically, CENG failed to promptly correct two improperly sealed cable penetrations at Ginna between manhole 1 and battery room 'B'. As a result, certain flooding scenarios could have resulted in flooding the battery rooms and the eventual loss of all alternating current (AC) and direct current (DC) power with no capability for using installed plant equipment for decay heat removal.
