In order to develop 3S-TRISO fuel for Pu-burner High Temperature Gas Reactor (HTGR), we conducted lab. scale experiments such as preparation test of simulated fuel kernel; CeO2-YSZ particle, and coating pre-test with simulated kernel. In the preparation test, based on the actual achievement of manufacturing fuel for High Temperature Engineering Test Reactor (HTTR)[1], we tried to fabricate some CeO2-YSZ particles through external gelation process. As a result, we successfully obtained the manufacturing parameters that can prepare good particles. In addition, we carried out some parametric coating test with fluidized-bed equipment and ZrO2 particle as simulated ZrC coated fuel kernel, and obtained the prospect of the possibility to coat the layer having desired thickness.
