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.”

Applications of the Monte Carlo method have been summarized relevant to neutron streaming problems of interest in the shield design for the fusion materials irradiation test facility. An improved angular biasing method has been implemented to further optimize the calculation of streaming, and this method has been applied to calculate streaming within a double bend pipe.
