| Abstract: | A filter for the selective and continuous removal of tritium or deuterium from an inert gas stream is proposed. It is based on the permeation of hydrogen and its isotopes through a highly permeable wall and the removal of for example tritium on the secondary side. The necessary concentration drop to the secondary side is effected by isotope exchange of the tritium atoms on the secondary side with water. The filter concept and the mathematical model, investigations of the influence of various parameters and the selection of the wall material are reported. |
