Abstract of the Disclosure A process is disclosed for the incremental enrichment of deuterium and/or tritium in a material which is suitable for the isotope exchange of deuterium and tritium with hydrogen. An apparatus especially adapted for the implementation of the process is also disposed. The novel process and apparatus for the enrichment of deuterium and/or tritium in water, in addition to a high transport speed for the molecules which participate in the isotope exchange, evidences a high enrichment factor for each enrichment stage and a high yield, so that, at a relatively small number of stages and low energy consumption, there is attainable an overall high degree of enrichment. For each enrichment stage, water containing deuterium and/or tritium is introduced into a carrier gas flow, reduced and set to a hydrogen (H2) partial pressure of maximally 100 mbar. Subsequently thereto, the carrier gas flow is conveyed along the primary side of an exchange wall which is suitable for the permeation of hydrogen, along the secondary side of which there is an additional carrier gas flow which con- tains a material adapted for the isotope exchange of deuterium and tritium with hydrogen in the gas phase thereof. The hydrogen isotopes, deuterium and/or tritium, which permeate through the exchange wall, after the isotope exchange, are bonded with the material in reaction product.
