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 novel ion and energy absorption system is proposed for use with tokamak diverters. The key to its feasibility is to accelerate the liquid-lithium working material outside the magnetic field, then have it pass through the magnetic field as free droplets. This avoids any significant magnetohydrodynamic effect on the liquid-metal motion. Thermal, fluid flow, and vacuum parameters are evaluated, and it is indicated that they have considerable flexibility.
