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 feasibility of heating TJ-II plasmas by electron Bernstein waves (EBWs) is studied. As a first approach, the Clemmov-Mullaly-Allis diagram is studied to explore the possible heating regimes, and the TRUBA ray- and beam-tracing code, which has been adapted to the complicated TJ-II geometry, is used to perform detailed calculations. The final result is that it is possible to heat plasmas by overcoming the cutoff density of electromagnetic modes by injecting the O mode and X mode at the first harmonic, exploiting the O-X-B1 and the X-B1 schemes. Transport simulations are performed to estimate the plasma parameters that are expected in those regimes and to study the transition from the X mode at the second harmonic to EBW heating at the first harmonic.
