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.”

Thermal analyses for the U.S. inboard and outboard shield and first wall of ITER have been performed utilizing the nuclear heating results obtained from the neutronics calculations. Several radial build configurations of the shield have been thermally analyzed. Different routes for the coolant are investigated to reduce the maximum temperature in shielding material which in turn reduces thermal expansion effects during ITER operation. The maximum thermal stresses are within the prescribed limits for the shield material at the maximum operating temperatures.
