NRC NOV – NOV (White)

On December 21, 2023, the NRC issued a notice of violation associated with a white significance determination process finding to Dominion Energy (licensee) at the Virgil C. Summer Nuclear Station. The white finding, an issue of low-to-moderate safety significance, involved the licensee’s failure to identify and correct the failure mechanism resulting in cracked piping/fittings in the emergency diesel generator (EDG) fuel oil lines, a condition adverse to quality, and a violation of Title 10 of the Code of Federal Regulations (10 CFR) 50, Appendix B, Criterion XVI, “Corrective Action.” This eventually led to the failure of the ‘A’ EDG fuel oil piping during testing on November 2, 2022.
