Tennessee has established a state-level regulatory framework for fusion energy, becoming the first U.S. state to do so following the Nuclear Regulatory Commission's decision to delegate oversight to Agreement States. The new rules mandate specific personnel training, safety committees, and radiological oversight for facilities like the proposed Type One Energy plant near Oak Ridge. This shift allows for state-specific licensing processes as the industry moves toward commercial deployment.

On June 9, Tennessee became the first U.S. state to implement its own regulatory framework for nuclear fusion machines. It's a notable step in the rapidly developing field of fusion regulation, and will help Tennessee prepare to regulate Type One Energy's proposed commercial fusion power plant near Oak Ridge.

Background and decision: In 2023, the Nuclear Regulatory Commission elected to integrate the regulation of fusion machines into the existing byproduct materials program, rather than classifying them—with commercial fission reactors—as utilization facilities. With this decision made, the onus has now fallen to NRC Agreement States to decide how they will regulate fusion machines.
