Nuclear Fatigue Rule at Watts Bar Nuclear Plant

Nuclear Power Group Standard Programs and Processes 03.21, Fatigue Rule and Work Hour Limits, includes rules regarding required average minimum days off for covered individuals, as well as overtime rules for how many hours can be worked in specific time periods. Our review of sampled employee and contract employee work hours and badging records for October 1, 2017, through June 30, 2019, identified no violations of nuclear fatigue rule minimum days off or overtime rules. However, we identified an area of deficiency related to Watts Bar’s performance of fatigue assessments. Additionally, we identified opportunities for improvement related to nuclear fatigue rule work-hour tracking and documentation.
