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.”

Amorphous hydrogenated carbon (a-C:H) is the nominal ablator to be used in French inertial confinement fusion (ICF) experiments. These capsules, containing the deuterium-tritium mixture, are developed for the LIL (Laser Integration Line) and the future Megajoule laser (LMJ) of the CEA. Coatings are prepared by glow discharge polymerization (GDP) with trans-2-butene and hydrogen. The films properties have been investigated. Laser fusion targets must have optimized characteristics : a diameter of about 1 mm for LIL targets and about 2.4 mm for LMJ targets, a thickness up to 175 μm, an outer and an inner roughness lower than 20 nm at high modes, a sphericity and a thickness concentricity better than 99%. This paper presents the first microshells obtained at the CEA with a GDP (Glow Discharge Polymerization) coater. Amorphous hydrogenated carbon shells of 175 μm with 1 mm or 2.4 mm diameter have been successfully prepared. The measured roughness at high modes is lower than 10 nm for a 30×30 μm characterization window.
