How Silver-Exchanged Zeolite Could Separate Tritium for Nuclear Fusion Fuel Recycling

A silver-exchanged zeolite separated three hydrogen isotopes and showed 244-fold selectivity for tritium over ordinary hydrogen at liquid-nitrogen temperature. The laboratory result could support more efficient fusion-fuel recycling, but capacity, radiation resistance, repeated operation and reactor-scale economics remain unproved.
