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 the compressional hydromagnetic (fast wave) mode is examined with respect to heating a minority helium-3 species in a fully catalyzed deuterium tokamak. In this paper we develop a rapid solution to analyze the two dimensional, steady state Fokker-Planck equation, with quasi-linear ICRF heating terms. This finite element solution for the minority helium-3 distribution function develops a high, anisotropic in the perpendicular velocity direction, energy tail as a result of ICRH. The rapidity of this method of solution makes it possible to conduct parametric studies which are not possible with other codes.
