Thermochemical hydrogen production process produces hydrogen from water by absorbing high temperature nuclear heat supplied by High Temperature Gas-cooled Reactors. This paper presents a result of a laboratory-scale demonstration experiment of the thermochemical hydrogen production by IS (Iodine-Sulfur) process. Hydrogen and Oxygen could be produced with stable rate and with molar ratio of 2 to 1, the stoichiometric ratio of water splitting. Also, the fluctuation of the composition of the process solution could be controlled to be lower than 3%. (author)
