PROCESS AND DEVICE FOR THE DECOMPOSITION OF TRITIATED WATER

摘要

Process for the decomposition of tritiated water and the recovery of basic tritium (T2) in which a metal is used (Me) which oxydizes in the presence of water according to the formula Me + xT2O -> MeOx + xT2. According to the invention, said metal is placed in an enclosure (4), the wall (3) of which is selectively permeable to hydrogen and its isotopes; the tritiated water is injected into said enclosure and the space (5) behind said wall is made to communicate with a hydrogen absorbing device (8) and its isotopes; and the injection of the tritiated water and said communication are stopped from time to time for the purpose of regenerating said metal, by supplying hydrogen or deuterium to said space (5) and by extracting water from the enclosure (4).
