On October 19, 2023, the NRC issued a notice of violation associated with a white significance determination process finding to Southern Nuclear Operating Company, Inc. (licensee) at the Joseph M. Farley Nuclear Plant, Unit 1. The white finding, an issue of low-to-moderate safety significance, involved the licensee’s failure to identify and correct a condition adverse to quality associated with the inadequate installation of a lube oil coupling assembly that resulted in the inoperability of the Unit 1 ‘B’ train (1B) emergency diesel generator (EDG). This failure resulted in a violation of Title 10 of the Code of Federal Regulations (10 CFR) 50, Appendix B, Criterion XVI, “Corrective Action.” With the 1B EDG inoperable, the licensee also failed to meet the Technical Specification Limiting Condition for Operations 3.0.1 and 3.8.1 between December 7, 2022 and March 3, 2023.
