High temperature gas-cooled reactor (HTGR) can produce a large amount of hydrogen due to high temperature heat supply capability. JAEA has started an HTTR heat application test project, which aims world's first hydrogen production demonstration utilizing direct nuclear heat. A hydrogen production facility will be newly constructed and will be connected to the HTTR. The objective of the test is to establish a safety design for coupling HTGR and hydrogen production facility through the licensing by the Nuclear Regulation Authority in Japan and demonstrate performance of components required for coupling between HTGR and hydrogen production facility. JAEA is currently conducting hydrogen production facility design as well as safety design and analysis of the HTTR. This presentation will show the overview and current status of the HTTR heat application test.
