This research offers a fuel conversion from cylinder type to plate type for solving the operation problems as a solution when the TRIGA reactor fuel production run out. The research has been implemented utilizing MCNP6 software to model and simulate the core of the TRIGA 2000 reactor plate type fuel. The geometry of the simulated reactor consists of a reflector, a moderator and a reactor tank. The fuel was U 3 Si 2 Al with 19.75% enrichment and the density was 2.96 gU/cm 3 , the reflector was graphite and the control rod was AgInCd. The first criticality value with 15 fuel assemblies and the 4 control rods position at 11.97cm from the top surface of the reactor core was (1. ± 0.00016) in agreement with the reference value for initial configuration of TRIGA reactor core was (1.00 ± 0.01).
