Flowsheet study of the thermochemical water-splitting ...

The Japan Atomic Energy Agency (JAEA) is performing research and development on the thermochemical water-splitting iodine-sulfur (IS) process for hydrogen production with the use of heat (temperatures close to 1000 °C) from a nuclear reactor process plant. Such temperatures can be supplied by a High Temperature Gas-cooled Reactor (HTGR) process.
