German team achieves first separation of tritium-containing hydrogen isotope mixtures using silver-exchanged zeolites

A team at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and partners recently demonstrated a new method for separating hydrogen isotopes using silver-containing zeolites, successfully separating hydrogen isotope mixtures containing radioactive tritium through a porous solid material for the first time. The research findings were published in Nature Communications. Future fusion power plants will require not only high-temperature plasma and strong magnetic fields during operation, but also a stable fuel cycle system for recovering, separating, and reusing deuterium and tritium. Inside a fusion reactor, deuterium and tritium participate in reactions and release energy, but the fuel is not completely consumed, and the residual gas may also contain ordinary hydrogen (protium), forming a mixture of protium, deuterium, and tritium...
