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.”

The use of fiber composite technology and finite element analyses on both micro- and macro-scale, can bring innovative solutions to the design of the divertor plate for future experimental fusion reactors. Overall divertor problems are discussed. An original and versatile solution is proposed and some promising results from a thermo-mechanical analysis are presented, using two- and three-dimensional modelling and a realistic heat flux profile, without separatrix sweeping. The effect of the third dimension is focused in this paper. Emphasis is also put on the integration of the micro- and macro-scale results. Finally inherent design improvements and weaknesses are discussed; the preliminary balance is highly positive.
