Neutronic calculation has been performed to high-temperature gas-cooled reactor (HTGR) that uses ZrC Triso-coated particle (TRIZO). TRIZO is the most reliable alternative to replace the SiC coating on coated fuel particles because of its superiority in resistance to high temperatures and resistance during the irradiation process. Neutronic aspect analysis of HTGR was carried out by calculating the k-inf and k-eff values on ZrC and SiC coating layers. The materials used were based on the Tri-isotropic (TRISO) coated particle standard used in HTTR 30 MWt, with uranium dioxide and thorium dioxide fuels based. The neutronic aspect with different fuels use ZrC coating layer is also investigated. The calculation shows similar behavior between thorium dioxide and uranium dioxide fuel with ZrC and SiC coating layer. The k-inf and k-eff with ZrC coating layer are lower than the SiC coating layer in both fuels. This value is related to the number of ZrC’s capture cross-section. Comparison between thorium dioxide and uranium dioxide fuel shows that thorium dioxide fuel has higher k-eff and k-inf with ZrC coating layer.
