Tritium test of cryogenic molecular sieve bed for He GDC gas cleanup by 60 SLM test loop

This work presents demonstrative test results of CMSB by simulated helium glow discharge exhaust gas condition in 60 l/min of flow rate. This work focused on H2 and HT adsorption and regeneration performance of CMSB and optimum regeneration procedure, so that the operation cycle time becomes smaller. Test results showed consistency with bench-scale experiments. Obtained engineering data are applicable for the design of the CMSB process for ITER He GDC gas cleanup. As the results of this work, it was demonstrated that CMSB process could clean up 54.3 SLM of He stream with H2(400) ppm+HT(0.5 ppm). Regeneration performance in various total pressure were obtained and evaluated by the calculation and clarified necessary information for determining the optimum regeneration procedure of CMSB which allow continuous operation in the shorter period of operation cycle (adsorption and regeneration). 6 refs., 5 figs., 1 tab
