The use of ZrC as a substitute for SiC has been proposed to improve the performance of coated fuel particles. In previous studies, a neutronic analysis on HTGR 30 MWt using ZrC and SiC has been done. The advance research conducted to see the effect of the use of TRIZO on HTGR with different power. In the present study, we use a power variation of 50-100 MWt and change the reactor geometry by apply additional fuel layer in the axial and radial direction from HTTR geometry as a reference. Neutronic analysis of the reactor was investigated by calculating the k-eff and k-inf values ​​using ZrC and SiC layers for coated fuel particle. Neutronic calculations are performed using the SRAC code with the JENDL 4.0 nuclear data library.
