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.”

Predictive simulations of target plasmas for the National Compact Stellarator Experiment (NCSX) were performed as part of the design effort. The resistive stability of these simulated target plasmas was studied using a quasi-cylindrical ' stability code, as has been done with some success for W7-AS plasmas. The plasmas were found to be classically unstable to an m = 2, n = 1 tearing mode during the start-up, but the 2/1 saturated island size in the target equilibrium was small, <2%. Inclusion of neoclassical effects resulted in negligible island sizes throughout.
