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.

The computational code for designing the resonant cavity of a gyrotron has been developed to design new gyrotrons for the future GAMMA 10(PDX). The developed code calculates the cavity RF profile function by simultaneously solving a set of relativistic single-particle equations of motion and wave equations to obtain a self-consistent solution in the dynamic system that accounts for the effects of the electron beam on the cavity field profile. Beam-wave interactions mainly occur in the uniform middle section of the resonator. The calculation results explain well experimental data of the gyrotron used in GAMMA 10 ECH system.
