Efficient management of hydrogen isotopes is critical for the operation of future nuclear fusion reactors. A fusion machine’s fuel cycle requires the precise separation, rebalancing, and removal of protium to maintain an optimal deuterium-tritium (D-T) mix. While cryogenic distillation and temperature swing adsorption are the current reference technologies for these tasks, both approaches involve a high tritium inventory, raising safety and resource challenges. This study explores palladium-silver (Pd-Ag) membranes as a promising low-inventory alternative. Read more
