DOE issues new NEPA rule and procedures—and accelerates DOME reactor testing
Meeting a deadline set in President Trump’s May 23 executive order “Reforming Nuclear Reactor Testing at the Department of Energy,” the DOE on June 30 updated information on its National Environmental Policy Act (NEPA) rulemaking and implementation procedures and published on its website an interim final rule that rescinds existing regulations alongside new implementing procedures.

Excitation of ion cyclotron resonance frequency (ICRF) waves in tokamak plasmas by using the waveguide antenna is investigated. To obtain the surface impedance of the plasma, the wave propagation equation for the fast wave is solved. The reflection/transmission coefficient is calculated for the parallel plates launcher that simulates the ridged waveguide. Dependence of the transmission coefficient on geometrical and plasma parameters is studied. It is found that the transmission coefficient can be of the order of 10%, comparable to that of the loop antenna. Non-plasma loss of the launcher is also discussed.
