The Japan Atomic Energy Agency has been conducting study on thermo-chemical Iodine-Sulfur (IS) process for water splitting hydrogen production. In design of the IS test equipment, it is important to design ceramics chemical reactors with high performance from the viewpoint of thermal hydraulics and structural integrity. A new simple hydraulic analytical code has been developed for considering sulfuric acid solution as a mixture of two components especially in the HSO decomposer. Complex flow with liquid-vaporized interaction involving chemical reaction will be characterized in the HSO decomposer. Based on the preliminary analytical results obtained with above mentioned code, conceptual investigation of structural integrity of ceramics decomposer was carried out by a general commercial FEM code.
