A design study of water detritation and hydrogen isotope separation systems for ITER

A preliminary design study of the combined electrolysis catalytic exchange (CECE) process by using existing plant technology at the Japanese heavy water reactor (Fugen) was carried out for International Thermonuclear Experimental Reactor (ITER). Because of the large separation factor, the required column height is substantially reduced compared with a vacuum water distillation (WD) column. A preliminary design study of the hydrogen isotope separation system (ISS) was carried out for the ITER fuel cycle based on a reduced hydrogen gas flow rate from the CECE plant, and a new ISS cascade configuration was proposed. Major process parameters of the CECE and the ISS were compared with the ITER-FDR process systems.
