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 new spectroscopic method for measurement of hot plasma parameters is developed. The method based on Hα profile monitoring. The profile was accurately calculated for a wide range of plasma parameters (ne∼1014÷1017 cm−3, Te∼1÷500 eV,) Use of the method in the experiment gives the electron density and ion temperature dependence from the time. Measurements was in a good agreement with diamagnetic loop dates.
