原子力機構は原子力エネルギーの多様な産業利用に向け、HTTR建設の許認可での経験及び知見を活用し、高温ガス炉固有の特徴を反映した、実用高温ガス炉の安全基準国際標化に向けた活動を実施している。本報告では、高温ガス炉コジェネレーションシステムの許認可に向けた研究開発ロードマップを示す。また、安全要件や設計基準事象選定方針等の検討結果や安全評価手法の確立に向けたHTTR試験計画を報告する。

Japan Atomic Energy Agency has been conducting research and development with a central focus on the utilization of HTTR, the first HTGR in Japan, towards the realization of industrial use of nuclear heat. On the basis of licensing experience through the HTTR construction, JAEA initiated an activity to establish an international safety standard for licensing of commercial HTGR cogeneration systems fully taking into account safety features of HTGRs. This paper explains a roadmap towards licensing of commercial HTGR cogeneration systems. A test plan using the HTTR to support the establishment of safety standards and safety analysis methods is also presented.
