Interim Enforcement Policy for Minimum Days Off Requirements

The U.S. Nuclear Regulatory Commission (NRC or the Commission) is revising its Enforcement Policy to include a provision allowing licensees enforcement discretion if they implement an alternative approach to meet the NRC's requirements for managing worker fatigue at operating nuclear power plants. This interim policy affects licensees subject to the minimum days off (MDO) requirements of the NRC's fitness for duty regulations and will remain in place until the NRC publishes a revised rule associated with the MDO requirements for managing fatigue.
