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.”

At scales appropriate to the National Ignition Facility, calculations indicate double shell capsules reach ignition conditions with room temperature fuel. Los Alamos is laying the groundwork for these double shell ignition targets with a preliminary campaign on Nova. The target design features a 260 μm O.D. inner glass capsule with an I.D. of approximately 200 μm, containing deuterium gas, centered inside a machined polymer shell. The central capsule was supported either with a 30 mg/cc foam or with two polymer films, each less than 0.1 μm in thickness. The materials, machining, assembly, and characterization of the targets are discussed.
