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.

A study of the high-energy part of the deuteron spectrum produced by the Frascati 1-MJ plasma focus device is carried out through measurements of (a) the energy distribution of prompt neutrons emitted by D(d, n) and 7Li(d, n) reactions using three time-of-flight spectrometers and (b) the total neutron fluence and the high-energy neutron fluence using silver- and lead-activation counters, respectively. The results clearly confirm the existence of an energetic deuteron beam, Eb = ≤2 to 4≥ MeV, and lower energy streams circulating in the plasma, Es ≅ 100 keV, responsible for the main part of the neutron production through the D(d, n) process, with the ratio of the two components, . The methodology of measurements and of data analysis described represents a definite improvement with respect to those described in previous publications.
