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 pulsed fusion reactor potentially influences many commercial plant design provisions. Provisions related to turbine fatigue performance are among those considered important. They are evaluated by varying several design/operating parameters, separately and in combination, to present tradeoffs among them. These parameters include pulse length and capacity of the thermal storage system. A very simple and fast running temperature/stress representation of the turbine is used for evaluations. Results for wet-steam turbines indicate that requirements for thermal storage are quite large (steam flow between 40 and 80% of full steam flow). Modeling assumptions, design options, and important operating considerations are highlighted.
