The present work discusses two different models of thorium irradiation in the TRIGA 2000 reactor core to compare the neutronic characteristics of irradiation of thorium dioxide (ThO 2 ) and thorium zirconium hydride (ThZrH). The Monte Carlo N-Particle (MCNP) Transport code, based on the Monte Carlo method, is used to design three dimensional models for TRIGA reactor core at typical operating power 2 MW. These models are used to determine the effective multiplication factor (k eff ) and neutron flux distribution. The ORIGEN code is used to calculate the 233 U isotope production. It is found that decreasing of k eff from the effect of hydride irradiation rod is a little lower than the oxide irradiation rod.
