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.

Equilibrium shape of a field-reversed-configuration plasma is controlled to maximize its poloidal flux. Plasma elongation is changed from 7.5 to 4.5 by adding a local field to the plasma due to the introduction of a control coil. The control field strength is about 10% of the confinement field. The plasma shape modifies while keeping its volume and the product of its poloidal flux and elongation constant. The poloidal flux is twice that of the uncontrolled plasma. Its flux confinement time also improved.
