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, βis based on the experience of DOE and other federal agencies, current technologies, regulatory requirements, and accepted industry practice.β

The ion cyclotron range of frequencies antenna design for the R tokamak (a proposal by the Institute of Plasma Physics, Nagoya University) is described. The design involves three types of antennas: a standard loop antenna, a panel heater antenna, and a waveguide antenna for ion Bernstein wave heating (IBWH). The standard loop antenna is made of aluminum alloy and has a simple structure because it has to be installed under radioactive conditions by deuterium-tritium neutrons. A new type of antenna called a panel heater antenna has been designed for high-power heating. It has a wide radiation area and is able to select a parallel wave number kβ. The feasibility of the waveguide antenna is also discussed in association with IBWH. The radiation from the aperture of the double ridge waveguide is estimated in a model experiment, where calculated surface plasma impedance is simulated by a dielectric load.
