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.”

An investigation aimed at identifying methods of flattening the power distribution in D-T blankets has been carried out. Three methods were identified which when used in conjunction produce power distributions which are significantly flatter than those produced by typical blankets. The peak-to-average power density ratio is reduced by over 50%, and the peak-to minimum power fall-off is reduced by a factor of five. Power flattened blankets achieve tritium breeding ratios and blanket multiplication which could be somewhat higher than those of typical blanket designs.
