DOE announces NEPA exclusion for advanced reactors
The Department of Energy has announced that it is establishing a categorical exclusion for the application of National Environmental Policy Act (NEPA) procedures to the authorization, siting, construction, operation, reauthorization, and decommissioning of advanced nuclear reactors.
According to the DOE, this significant change, which goes into effect today, “is based on the experience of DOE and other federal agencies, current technologies, regulatory requirements, and accepted industry practice.”

Releases of tritium and activation products from a reference fusion reactor under normal operating conditions were evaluated for the radiation doses to local and global populations. Maximum annual total body dose commitment from all sources of effluents to an individual at the plant boundary is 0.5 mrems. The annual total body dose commitment from all effluents to the population of 1 million persons living within 80 km of the plant is 7 person-rems. These exposures are small fractions of the doses resulting from existing background radiation. Global doses due to tritium and 14C releases from the reference fusion reactor are small fractions of doses resulting from naturally occurring tritium and 14C.
