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.”

Alpha healing, alpha containment, and alpha stabilization effects are studied in the fusion ignition experiment IGNITEX. The IGNITEX device offers the possibility of producing fusion-ignited plasmas with ohmic heating alone. It is shown here that operating regimes with high probability for ignition and simplicity of operation are possible in IGNITEX. Time-dependent simulations showing the ohmic heating and alpha healing coupling through the discharge are presented. The characteristics for alpha transport with magnetic field perturbations are analyzed in detail using Monte-Carlo techniques. The stability of internal MHD modes and the interaction with alpha particles in the inner confinement region of ignited plasmas is studied. Specifically, the stability of resistive internal kinks, ideal internal kinks, and fishbones is presented. It is shown that a quiescent regime of operation is possible during the ignited phase in IGNITEX. Because of its ample ignition margin, its high alpha containment, and the possibility of operation far from marginal stability and the possibility of ignition operation with quiescent regimes in the inner region of the plasma, it is concluded that the IGNITEX device can produce fusion-ignited plasmas in a simple manner.
