JAEA (Japan Atomic energy Agency) has been designing a Small-sized Co-generation High Temperature Gas-cooled Reactor (HTGR), named High Temperature Reactor 50-Cogeneration (HTR50C), on the basis of design, construction and operational experience of the Japan's first HTGR, HTTR. The HTR50C that can be used not only for electric power generation but also for hydrogen production and district heating is considered one of the most promising nuclear reactors for countries where sufficient infrastructure such as power grids is not provided. Specification, equipment configuration, etc. of the HTR50C were determined, and also economic assessment was made.
