What We Regulate

The NRC licenses all individuals who either operate or supervise the operation of the controls of a commercially owned nuclear power reactor or a test/research (i.e., non-power) reactor in the United States. Although the regulations in this area generally apply to both power and research and test reactors, this site focuses primarily on the operator licensing activities at power reactor facilities. For more information on research and test reactors operator licensing, please refer to Operator Licensing for Research and Test Reactors.

As of July 2019, there are approximately 3,900 active NRC-licensed power reactor operators in the United States.
