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 laminated carbon-carbon (C/C) composite is candidate material for plasma-facing components in fusion reactors. Its thermal shock strength must be evaluated for an application to the components facing the high-temperature plasma field. However, few studies have been done. A laser irradiation method newly proposed was applied effectively to lamination of C/C composite for the evaluation of thermal shock strength by subjecting a heat flux up to 27 J/mm2 on the specimen surface. By introducing the critical power density at which the material fracture occurs, thermal shock strength was obtained. It was concluded that the critical power density could be a new measure to evaluate thermal shock strength for laminated C/C composite.
