Abstract

A computer model was designed using MCNPX code to simulate and analyze the conversion process of HEU to LEU of IAEA 10 MW research reactor core. The conversion process are performed using six cycles. First cycle devoted for HEU core, four mixed cycles and the sixth cycle for LEU core. The multiplication factor of the core, the power distribution and fuel burnup were determined at both the beginning of cycle (BOC) and end of cycle (EOC) in the case of HEU and LEU. The results of the present model are compared with previously published results and good agreement was found.
