    The invention relates to devices for the isolation and storage of hydrogen isotopes and can be used in the preparation of tritium and deuterium.
    The purpose of the invention is the release of hydrogen isotopes at constant pressure.
    The drawing shows the proposed device, a General view.
    A device for sorption, storage and release of hydrogen isotopes includes a container 1 with a source of low-pressure hydrogen isotope having a partial pressure of about 10 -10 Pa, a container 2 filled with a non-evaporating getter material having an isothermal sorption characteristic, and an additional container 3 filled with getter material having a nonlinear sorption characteristic
    A pumping system comprising a forevacuum pump 4 (rotary type) and a turbomolecular pump 5 is connected to containers 2 and 3.
    The device has a reservoir 6 for storing hydrogen isotopes. Valves 7-11 connect container 2 and 3, respectively, with pumps 4 and 5, among themselves, with capacity 1 and reservoir 6. As the most acceptable non-evaporating material for container 2, such materials can be used that have the ability to permanently absorb the active gases and reversible adsorb hydrogen isotopes at low pressures in accordance with a linear isothermal sorption characteristic. Preferred are materials that adsorb isotopes (L 00

    Doda to a concentration of 3x10. kg about 25 ° C and at an equilibrium pressure of 40 3 Pa. Such requirements are met by materials selected from the group including Zr-AI alloy, Zr-Fe alloys, alloys in which Mi is selected from the group containing 1Mb and V, and Mg is from the group containing Fe and N1. The absorbent material in additional container 3 must have a nonlinear isothermal sorption characteristic and must absorb hydrogen isotopes at ambient temperature, released when the getter material is heated in container 2, and itself releases hydrogen isotopes when heated at constant pressure, which The latter is above the pressure at which the hydrogen isotope is released from the getter material in container 2. The most typical of such material are Zr-alloys and La-Ni-AI alloys.
    The device works as follows.
    Contaminated, for example, tritium with a content of about one percent oxygen and about one percent of nitrogen is found in tank 1. In container 2, there is a getter material, for example, an alloy in the form of microparticles of the following composition,% Zr 62; V 30 and Fe 8. In the additional container 3 there is an alloy in the form of microparticles of the following composition,%: Zr 50; V 25 and Fe 25. Pumps 4 and 5 are put into operation. With valve 10 open, non-evaporating getter material located in conveyor 2 absorbs active gases and reversibly absorbs hydrogen isotopes
    at ambient temperature and low pressure in accordance with the isothermal sorption characteristic to the equilibrium pressure of the hydrogen isotope in this material. Close valve 10, open valve 9, then heat ("8000C} container 2 to activate the gas absorbing material in it, after which the gas absorbing material in the additional container 3 absorbs the hydrogen isotope at ambient temperature. Close valve 9 and open valve 11 The additional container 3 (200 ° C) is heated to release the water isotope at a constant pressure of approximately 10 5 Pa. Pure tritium is introduced through valve 11 into reservoir 6.
