ANS joins others in seeking to discuss SNF/HLW impasse
The American Nuclear Society joined seven other organizations to send a letter to Energy Secretary Christopher Wright on July 8, asking to meet with him to discuss “the restoration of a highly functioning program to meet DOE’s legal responsibility to manage and dispose of the nation’s commercial and legacy defense spent nuclear fuel (SNF) and high-level radioactive waste (HLW).”

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 k‖. 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.
