Processing highly tritiated water desorbed from molecular sieve bed using PERMCAT

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

“…• Stage 1-b: Some MSB previously loaded with detritiated HTW were placed upstream of the PERMCAT for a further detritiation. Few tests were performed to study the HTW release rate with respect to temperature during regeneration, showing that a careful temperature programmed desorption can be applied to produce a controlled water vapour feed into the PERMCAT [23]. • The final configuration under completion shall integrate a microchannel catalytic reactor (CCR) [24] that will allow performing a vast experimental program while minimising waste production (MOR has to be replaced and disposed off).…”

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

“…Given the throughput foreseen in ITER TBM, the technical unit presented in this study should in a first approach fulfill the required processing performances when regenerating the molecular sieve bed (MSB). In parallel, at a smaller scale but with tritium [19], the experimental demonstration of a combination of a MSB and a PERMCAT [20] is under progress using the CAPER facility at TLK [21].…”
