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.

In the tandem mirror GAMMA 10, a 500 kW gyrotron was newly equipped in the central-cell ECRH system, following the plug ECRH systems. Then, the transmission system for the central-cell ECRH, including a taper, mirrors and a polarizer, has been designed correspondingly. The guidelines to design the transmission system are to make the beam cross section axisymmetrical on the resonance surface with a high power transmission rate and high heating efficiency. According to the guidelines, mirrors in the launcher systems have been designed with our electromagnetic code. Controlling polarization of the incident microwave is achieved with a polarizer for raising heating efficiency.
