The fabrication of the 2nd loading fuel for the HTTR has been started from October 2002 and completed successfully by March 2005. While the fabrication of the 2nd loading fuel for the HTTR, the fuel kernels, coated fuel particles and fuel compacts has inspected to compared with fuel fabrication specification. As the result of these inspections, we confirmed a good quality of the 2nd loading fuel for the HTTR as similarly the first loading fuel for the HTTR. This report describes fabrication data of fuel kernels, coated fuel particle and fuel compacts of HTTR 2nd loading fuel. The fabrication data of this report could be the basis of the study of fuel and fission product release behavior etc. on the HTTR operation, and contribute to post irradiation examinations of HTTR fuel in the future.

In the high temperature gas-cooled reactors (HTGRs), refractory coated fuel particles are employed as fuel to permit high outlet coolant temperature. The High Temperature Engineering Test Reactor (HTTR) employs Tri-isotropic (Triso) coated fuel particles in the prismatic fuel assembly. Research and development on the HTTR fuel has been carried out spread over about 30 years, in fuel fabrication technologies, fuel performance, and so on. Furthermore, for upgrading of HTGR technologies, an extended burnup TRISO-coated fuel particle and an advanced type of coated fuel particle, ZrC-coated fuel particle in order to keep the integrity at higher operating temperatures has been developed. The present paper provides experiences and status of research and development works for the HTGR fuel in the HTTR Project.
