NRC reorganization aims to speed up licensing
The Nuclear Regulatory Commission announced yesterday that it is launching a significant reorganization to streamline decision making, consolidate functions, and align with national goals for more efficient licensing and deployment of new nuclear technology.
The changes are intended to meet the requirements outlined in President Trump’s Executive Order 14300, “Ordering Reform of the Nuclear Regulatory Commission,” and EO 14210, “Implementing the Department of Government Efficiency Workforce Optimization Initiative.”
