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 method for the production of a foam filled target with two regions of different densities is described in this paper. These two different density regions are separated by a 1 μm thick film, with a roughness of 5 μm rms peak to valley. The two regions are filled with a homogeneous, different density foams. These targets were designed to investigate the Richtmyer-Meshkov instability in the plasma region. The production of these targets using the in-situ polymerization technique is described. Several approaches for the production of these targets are examined. Triacrylate foams with densities of 40 mg cm−3 and 200 mg cm−3 were used in the targets.
