On November 6, 2020, the NRC issued a Notice of Violation and Proposed Imposition of Civil Penalty (CP) in the amount of $903,471 to the Tennessee Valley Authority (TVA) for multiple violations of NRC requirements. The first violation, a Severity Level (SL) III violation of 10 CFR Part 50, Appendix B, Criterion V, involved the failure to follow procedures. Specifically, main control room (MCR) staff failed to ensure shift operations were conducted in a safe and conservative manner; did not stop when unsure and proceed in a deliberate and controlled manner; did not validate available information; allowed production to override safety; and proceeded in the face of uncertainty. The second violation was an SL II violation of 10 CFR 50.9(a) with a proposed CP of $303,471. Specifically, a TVA employee failed to provide complete and accurate information during an interview with the NRC Office of Investigations regarding the startup on November 11, 2015. The third violation was an SL III violation of 10 CFR Part 50, Appendix B, Criterion V with a proposed CP of $300,000. Specifically, a TVA operations procedure supervisor and engineer/procedure writer changed a step in the Watts Bar Nuclear Plant Unit-1 startup procedure by using an improper change process. This change altered the technical intent of the procedure and allowed the startup to continue without first achieving a specific reactor temperature. Finally, an SL III Problem was issued to TVA for violations of 10 CFR Part 50, Appendix B, Criterion XVII and 10 CFR Part 50, Appendix B, Criterion V, with a proposed CP of $300,000. Specifically, during a November 11, 2015 startup, with only excess letdown available for pressurizer level control, pressurizer level rose uncontrollably until MCR operators placed another system in service to abate the pressurizer water level rise. However, the operators failed to follow approved plant procedures and failed to make control room log entries to accurately depict the event and as
