Japan Atomic Energy Research Institute (JAERI) has been conducting R&D on HTGRs and hydrogen production method focusing on thermochemical IS process. In the IS process, sulfur trioxide (SO_3) decomposition reaction works as the oxygen generation reaction where gaseous SO_3 is decomposed into SO_2 and O_2 in the presence of solid catalysts using high temperature heat of about 900℃ supplied by HTGRs. A concept of SO_3 decomposer was developed which features plate-type heat exchanger made of SiC ceramics, in which the heat of reaction is supplied by high temperature helium gas, and a model of the heat-exchanging units was successfully test-fabricated. Also, a test facility was constructed in order to examine the catalyst performance at temperatures of up to 850℃, and pressures of up to 0.75MPa.
