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.

Experimental and analytical studies on hydrogen-tritium isotope separation by a CECE process with a LPCE column have been carried out in order to apply it to the water detritiation system for fusion reactors. Kogel catalysts and Dixon gauze rings were mixed at a certain ratio and packed in the column in a random manner. Performance tests of tritium separation by the column of 1 m length and 2.5 cm I.D. were performed at 101 kPa and 343 K. The maximum value of the separation factor was 19200 when the flow rate of hydrogen gas was 5 L/min. The optimum value of catalyst packing ratio was obtained as 35 % by the analysis using the channeling stage model. The values of separation factors predicted by the model corresponded with measured ones very well.
