Deep Fission to break ground this week
With about seven months left in the race to bring DOE-authorized test reactors on line by July 4, 2026, via the Reactor Pilot Program, Deep Fission has announced that it will break ground on its associated project on December 9 in Parsons, Kansas. It’s one of many companies in the program that has made significant headway in recent months.

A new tritium removal system using gas separation membranes has been studied to develop more compact and cost-effective system for a fusion reactor. To obtain necessary parameters, which are directly scale able to the ITER Atmospheric Detritiation System, the basic tritium recovery performance was investigated with a scaled polyimide membrane module (hollow-filament type : 10 m3/hr ) loop. The result shows that the H2 recovery ratio from N2 or Air was more than 99 % or about 97 %, respectively, at flow rate ratio of permeated/feed =0.1, feed & permeated side pressures = 2580 & 80 torr, and module temp. = 293 K. Tritium (HT) recovery function was almost the same of H2 recovery, even though the total hydrogen concentration was a few ppm in the feed of module. H2O recovery performance was better than hydrogen recovery. These recovery functions were improved effectively decreasing the pressure ratio of permeated/feed of module.
