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.”

A relatively simple and low cost first wall system concept for a fusion ignition experiment is proposed and analyzed here. The basic idea is to use plasma gun technology to spray a thin layer of beryllium over the inside surface in the vacuum vessel. This concept is analyzed for the fusion ignition experiment IGNITEX. To minimize peaking factors during regular operation, a continuous limiter plasma control is envisioned. With presently available data on beryllium coatings, a thermomechanical stress analysis during a major disruption process at ignition is analyzed. It is concluded that the basic concept of the full beryllium coating over the vacuum vessel is feasible on a preliminary basis. Some research and development needs in this area are discussed.
