NRC CAL – NOV (White)

On November 25, 2014, the NRC issued a Notice of Violation associated with a White Significance Determination Process finding to Omaha Public Power District (OPPD). The finding involved the failure to properly implement high energy line break and environmental qualification design requirements at the Fort Calhoun Station. OPPD was cited for a violation of 10 CFR Part 50, Appendix B, Criterion III, Design Control, involving the failure to assure that applicable regulatory requirements and the design basis were correctly translated into specifications, drawings, procedures and instructions. Specifically, the licensee failed to fully incorporate applicable design requirements to ensure that components subjected to a harsh environment maintained the capability to shut down the reactor and maintain it in a safe shutdown condition following a postulated high energy line break.
