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.

Lebedev Physical Institute conducts a wide research and development program to supply targets for inertial fusion energy (IFE) research. Current essential results in that area include the following: (a) A free-standing target (FST) system has been created, which allows the filling, layering, characterizing, and placing of targets into a test optical chamber by injection at a rate of 0.1 Hz, (b) a special physical layout has been developed to carry out the layering experiments in a wide range of target diameters including reactor scaled ones, and (c) the reconstruction algorithms and scan system are under way to complete the FST system with a new subsystem for univalent target characterization based on microtomography. Specific issues for future IFE target technology and injection research are discussed, which include (a) adding a small doping to the fuel to form a cryogenic layer in a glassy state, (b) using large shells with a metallic layer onto the outer surface to shorten the layering time for reactor targets, (c) the cell for target motion driving application to FST technology, and (d) designing a prototypical facility for repeatable target fabrication and injection.
