🇯🇵 JP · Active
The Japan Atomic Energy Agency (JAEA) is Japan's national nuclear research and development agency, established in October 2005 by merging two predecessor bodies, and headquartered in Tokai, Ibaraki Prefecture. It operates research reactors including the High Temperature Engineering Test Reactor (HTTR) and the Jōyō fast reactor at its Oarai centre, and has designed high-temperature gas-cooled power reactors, including the GTHTR300 and the smaller HTR50S, neither built. Its predecessor ran the JT-60U tokamak, which this dataset lists under JAEA. In April 2016 JAEA transferred some of its laboratories to the body now called the National Institutes for Quantum Science and Technology (QST).
- Sector
- Fission
- Technology
- High-temperature gas-cooled reactor
- Role
- National laboratory, Research institute, Reactor developer
It is the operator of record for 7 facilities, 4 of them operating. Measured results for JT-60U are listed below.
Terms
- High-temperature gas-cooled reactor
- Helium-cooled and graphite-moderated, running far hotter than a water reactor. Fuel is TRISO particles, typically formed into pebbles or prismatic blocks, at LEU or HALEU enrichment depending on the design. The high outlet temperature suits industrial process heat as well as electricity.
