## Abstract

The U.S. Nuclear Regulatory Commission (NRC or the Commission) is amending its regulations governing the fitness for duty of workers at nuclear power plants. These amendments allow holders of nuclear power plant operating licenses the option to use a different method from the one already prescribed in the NRC's regulations for determining when certain nuclear power plant workers must be afforded time off from work to ensure that such workers are not impaired due to cumulative fatigue caused by work schedules.
