HTGR can provide high temperature which is used for non-electric application such as H production, process heat, desalination, etc. as well as for power generation. JAEA resumed the HTTR in 2021 without major reinforcements due to its inherent safety features. A safety demonstration test simulating loss of core cooling was carried out in 2022. HTGR is expected to be a promising system to attain carbon neutrality. A new project was launched to demonstrate H production by using the HTTR. R&D on nuclear and renewable hybrid energy system is underway toward carbon neutral society. Safe, sustainable and flexible use of nuclear are studied.
