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 wat er reactor (Fugen) was carried out for International Thermonuclear Experime ntal Reactor (ITER). Because of the large separation factor, the required c olumn height is substantially reduced compared with a vacuum water distilla tion (WD) column. A preliminary design study of the hydrogen isotope separa tion system (ISS) was carried out for the ITER fuel cycle based on a reduce d hydrogen gas flow rate from the CECE plant, and a new ISS cascade configu ration was proposed. Major process parameters of the CECE and the ISS were compared with the ITER-FDR process systems. (C) 2000 Elsevier Science B.V. All rights reserved.
