In the field of HTGR fuel, JAEA has carried out a lot of research and development works in the frame of the High Temperature Engineering Test Reactor (HTTR) Project. The fuel fabrication technologies were developed with the collaboration of the Nuclear Fuel Industry Co. Ltd.. Fuel performance was investigated by Oarai Gas Loop-1 and capsule irradiation tests, which were installed at the Japan Materials Test Reactor. The fuel performance and fission product behavior are under investigation through the HTTR operation. For upgrading of HTGR technologies, JAEA has also developed an extended burnup TRISO-coated fuel particle, and an advanced type of coated fuel particle. This paper provides experiences and present status of research and development works for the HTGR fuel.
