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.”

The graphite-based first wall of Tore Supra is designed to sustain particle and heat exhausts under steady-state conditions (additional power of 25 MW and 30-s pulse duration). Therefore, state-of-the-art brazing techniques were developed for the plasma-facing armor, such as the inner first wall, pumped limiters, and ergodic divertor structures. The different plasma-facing components are described, and the brazing techniques and quality control measures are discussed. Results of heat flux testing and performance during plasma operation are also reported.
