Abstract
Printed-circuit type multi-stream heat exchanger was designed and fabricated to produce high-temperature steam and air
simultaneously from high-temperature helium heated using the helium loop, which is simulating VHTR (Very-High Temperature
gas-cooled Reactor). This study describes the design methodology and the heat transfer performance evaluation
results of the multi-stream heat exchanger for stable supply of high temperature steam and air to a 30 kWe SOEC (solidoxide
electrolyzer cell) system to produce hydrogen with high-temperature nuclear reactor systems. In order to control the
steam supply above 700
