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.

High density helicon plasma is produced by a 13.56 MHz rf discharge under an IGBT-pulsed expanding and strong magnetic field, where the compact solenoid (inner diameter of 10 cm and 616 turn) is used for the formation of the magnetic field. The solenoid current is pulsed by the IGBT device with a pulse width of 20-40 msec. The solenoid current and the resultant magnetic field strength are proportional to the charging voltage to the capacitor. In the presently used solenoid and circuit, the maximum current and the resultant field strength are about 56 A and 3 kGauss, respectively. For the rf power of about 700 W, the high density plasma of about 4 × 1012 cm-3 is achieved. Above the field strength of about 1.6 kGauss, the source plasma density is constant, while the downstream density increases due to the suppression of the radial loss of the plasma particles.
