 note = {An exhaust detritiation system using commercially available hollow fiber-type polyimide membrane modules, a PM system, was installed and applied for tritium recovery in the vacuum vessel purge gas of a large fusion test device. The PM system is operated annually and there were no serious malfunctions after starting the operation for approximately 2.5 y. The continuous recovery of tritiated water without the heating operation and the switching of valves as well as the regeneration operation of molecular sieves, was demonstrated. The tritium in the process gas was successfully recovered by the PM system even though the average tritium concentration at the inlet of the PM system was less than the order of 10−3 Bq/cm3. The detritiation factor and tritium recovery ratio were greater than 103 and 0.97, respectively. The tritium concentration at the outlet of the PM system was maintained in the order of 10−6 Bq/cm3 irrespective of the tritium concentration at the inlet of the PM system. Thus, the operating data indicates that the PM system has a potentially higher detritiation factor than DF = 103., The exhaust detritiation system using a polymer membrane was operated for 2.5 y., There were no serious malfunctions after starting the operation., The operating data indicates that the system has a potentially higher detritiation factor than DF = 103.},
