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 total neutron cross section of 58Fe has been determined in the energy range from 7 to 325 keV by a transmission measurement using samples enriched in the 58Fe isotope. The data have been shape-fitted by means of an R matrix multilevel formalism to extract resonance parameters for s and l > 0 wave resonances. The s-wave strength function was determined to S0 = (4.3 ± 1.9) × 10-4.
