Nuclear Hydrogen Production Process Reactors

ByAtsuhiko Terada, Hiroaki Takegami

Nuclear hydrogen production processes such as steam reforming of methane [1-4], thermochemical water decomposition [5-8], and high-temperature steam electrolysis [9-11] employ a wide range of thermal and chemical reactors and other equipment, for example a steam reformer (SR) or chemical decomposer, which are designed to meet safe and economical performance requirements. Typical requirements are structural integrity at  service temperature and pressure that can approach to 900°C and 4 MPa, heat and  resistance to corrosive process ¦uids, affordable material and fabrication cost, and sufŒcient life time.  Since chemical reactors to utilize nuclear heat and electricity for
