Times Cited Count：2 Percentile：61.39(Nuclear Science & Technology)Aiming to establish coupling technologies between a high temperature gas cooled reactor and a hydrogen production plant, JAEA has initiated the HTTR Heat Application Test Project and is conducting the safety design and the safety analysis for the licensing of the HTTR Heat Application Test Facility. The present study proposed a relative evaluation methodology for the demarcation of applicable laws and design standards for the nuclear hydrogen production system and applied it to the HTTR Heat Application Test Facility. The evaluation results showed that a candidate applying the High Pressure Gas Safety Act to the Heat Application Test Facility (hydrogen production plant) and design standards established under the High Pressure Gas Safety Act to the steam reformer did not show the lowest category in any of the metrics, and was proposed as the most superior demarcation option for the HTTR Heat Application Test Facility.

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.
