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 possibility of burn control by hydrogen feeding was investigated for tokamak plasma under a self-sustained condition. When fusion power shifts higher than a target value, increases in hydrogen feed rate can lower the power by a reduction in ion temperature due to enhanced hydrogen density. Conversely, when the power shifts lower than the target, stopping hydrogen feeding and exhaust can increase the power through an increase in ion temperature due to reduced hydrogen density. Especially in the latter, in order to enlarge the recoverable magnitude of power shift, it is necessary to select a self-sustained condition having the highest hydrogen density. The results confirmed the possibility of burn control by hydrogen feeding.
