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.”

We investigate the heating characteristics of a helical antenna in comparison with the previously studied slot antenna1. In the present work, the electromagnetic field and antenna impedance are calculated using a newly designed current model for helical antenna. As the numerical results, the dependence of various components of the resistance on plasma density and external magnetic field are compared with slot antenna.
