Nuclear Fatigue Rule – Browns Ferry 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 fiscal years 2017 and 2018 identified no violations of nuclear fatigue rule (NFR) minimum days off or overtime rules. However, we identified areas of deficiencies with Brown Ferry's performance of (1) fatigue assessments and (2) NFR compliance reviews. Additionally, we identified areas for improvement related to NFR work-schedule tracking.
