Research Field Fusion Fuel Cycle Technologies

In the research field  ´Fusion Fuel Cycle Technologies´ we are developing technologies for the treatment of the exhaust gas of a fusion power plant, which consists of unburnt hydrogen isotopes, noble gases, and impurities. For this purpose, we are working on a novel concept for the separation of hydrogen in ultra-pure form, on new vacuum pumps with liquid metals as operating fluid (diffusion pumps, ring pumps), and on improved concepts for the separation of the individual hydrogen isotopes from a mixture. In addition, we are developing novel computational codes that allow to calculate rarefied gas flows self-consistently over the whole range of the Knudsen number, i.e. from a continuum flow to a free molecular flow.
