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 basic fusion ignition experiment IGNITEX can achieve plasma ignition through the use of high toroidal fields (20 T) and ohmic heating. The experiment will operate in a pulsed tokamak mode with one discharge every two hours. The single-turn-coil system will be driven by homopolar generators and will be cooled by a liquid nitrogen bath. The experimental program will stretch over a three year period with the first D-T fueled discharges taking place after about 19 months of operation. Hands-on maintenance is possible both inside and outside the primary shielding due to the low activation levels of the experiment. This low activation is because of the almost complete coverage of the vacuum vessel by the thick copper magnetic coil system and the single-turn coil design which does not require the usual high activation laminate materials. IGNITEX systems are designed to provide high reliability and simplicity to extend machine availability in the fusion ignition regimes.
