Tritium bound in the gas impurities generated in a tritium facility must be removed before impurities are released into the environment. The catalytic reactions of hydrogen isotopic exchange allow the replacement of tritium in impurities with protium, and the transfer of tritium into molecular hydrogen, which can then be sent to the isotope separation system. The efficiency of a detritiation system based on hydrogen isotopic exchange reactions and operating in a once-through or circulation regime with either counter-current or co-current catalytic reactor is considered. The number of parameters, such as the duration of circulation, gas mixture flow rate, amount of protium injected into the detritiation system, are estimated.
