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.

Quantum molecular dynamics calculations at constant temperature have been carried out in order to study the interaction between atomic oxygen and a hydrogen saturated graphite surface. It has been shown that atomic oxygen reacts at 300 K with the adsorbed hydrogen atoms to form hydroxyl radicals and water molecules. Part of these residue radicals adsorbs on the graphite forming hydroxylated structures. A study on the stability of these structures has shown that OH radical desorption begins at 500 K and formation of water molecules occurs by reaction between a desorbed hydroxyl radical and a hydrogen atom extracted from a neighboring adsorbed hydroxyl. The water molecules only very slightly interact with the graphite surface and are ejected into the gas phase.
