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.

Neutron capture by a sample enriched in 41K and by a natural potassium sample (93.26% 39K) was measured at the Oak Ridge Electron Linear Accelerator as a function of neutron time of flight over a 40-m flight path. Resonance peaks were fitted by a least-squares fitting program to obtain Breit-Wigner resonance parameters. The energy range extended to all resonances below 153 keV. Corresponding average capture at a temperature typical of stars, kT = 30 keV, is calculated as (11.8 ± 0.4) mb for 39K and (22.0 ± 0.7) mb for 41K.
