  • The US electricity system is part of the nation's critical infrastructure. Providing regulatory flexibility that maintains safety during the COVID-19 pandemic helps to ensure safe and reliable electric power during a national emergency.

  • The NRC's March 28 letter contains the regulatory basis for our determination that such exemptions, if approved, will maintain reasonable assurance of safety during a defined, limited period of flexible work hour controls.

  • The NRC is prepared to use its existing authority in granting, upon request from individual licensees, exemptions from the work hour controls specified in 10 CFR 26.205(d)(1)-(d)(7), if alternate administrative controls are used to manage worker fatigue.

  • Any granted exemptions will ensure work hour controls and worker fatigue management appropriately maintain licensee flexibility in using personnel resources to most effectively manage the impacts of the COVID-19 PHE on maintaining the safe operation of nuclear power reactors.
