Abstract
Fuel cell seems to be one of resolutions for global warming so that large amount of feed hydrogen to fuel cell will be necessary. To meet the hydrogen demand, new hydrogen production system without CO2 emission will be required.
The High Temperature Gas-cooled Reactor (HTGR) can produce high temperature helium gas that is around 950°C. Hydrogen production using HTGR is now being studied all over the world. The Japan Atomic Energy Research Reactor (JAERI) is planning the demonstration test of hydrogen production using the High Temperature Engineering test Reactor (HTTR). A design study on the steam reforming hydrogen production plant to be connected to the HTTR has been performed.
In this report, interface technology between HTGR and hydrogen production plant is mainly discussed. In addition, safety requirements for hydrogen production plant are described. Flow scheme of the HTTR hydrogen production system is established to achieve stable controllability. Plant simulation analysis shows good performance of start up sequence. Component design of steam reformer and isolation valve for hot helium pipe that are special components in the HTTR hydrogen production system is presented. Heat and mass balance of hydrogen production plant is settled based on parametric survey of hydrogen production rate.
