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 method for calculation of proton dose in a receiver behind a combination electromagnetic and material shield is described. Dose calculations for a typical Van Allen proton spectrum and three solar-proton-event spectra are presented. In general, the electromagnetic shield stops protons below a certain threshold energy and reduces the number and energy of protons above this energy, and material shielding is more effective against these protons of reduced energy since proton stopping power increases with decreasing energy.
