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 separation of hydrogen isotopes is an essential element for tritium processing systems. A new process invented at the Savannah River Site, has been developed at Valduc facility: Thermal Cycling Absorption Process. This system uses palladium packed in a column to absorb a stream of hydrogen isotopes. By repeated heating and cooling cycles, the hydrogen isotopes successively desorb into a capacity and go back onto the column. The thermal cycling creates differences in the Pd separation factor for the hydrogen isotopes inducing the concentration of tritium at one end of the column and the concentration of the lighter isotopes at the other end. This paper presents experimental results obtained with a full-scale facility which has been installed in a glovebox so as to treat weakly tritiated gases. Experimental data collected on this device working with several isotopic mixtures are presented and compared to simulation results.
