Development of a technical scale PERMCAT reactor for processing of highly tritiated water

Overview of R&D at TLK for process and analytical issues on tritium management in breeder blankets of ITER and DEMO

“…• The size and capacity of PERMCAT reactors have been continuously increased (cf. Table 2) to end up with a cascade of two technical reactors in series to process higher throughputs (multitube reactor) with better performances in terms of detritiation factor (DF of two reactors in line equals DF of one reactor to the square) [18,19]. • The process simulation has been progressively refined to integrate in one dimension the isotope exchange and side reactions [20], and later the axial dispersion has been included as well; development of 2D simulation is in progress [21].…”

Processing highly tritiated water desorbed from molecular sieve bed using PERMCAT

“…Several different PERMCATs were designed, manufactured and operated in TLK. Currently the decontamination of HTW containing considerable amounts of tritium using PERMCAT reactors is under investigation at TLK using the CAPER facility [13].…”
