In this study, applicability of mixed (Th + 233U)O2 fuel in the CANDU reactors and influence on the reactor performance was investigated. In order to achieve this purpose, mixed 98 % ThO2 + 2 % 233UO2 fuel was used. Neutronic data were calculated by using the aid of one dimensional computer system code of SCALE 4.4a. The criticality and the burn-up values of the reactor were been calculated by full power operation for a period of 20 years. The results showed that the during criticality started by k∞=∼1,3 and after the second year it remained above k∞=1,06 for 20 years. Burn-up grades were calculated as 45.216 MW.D/MT after the second year and as 558.061 MW.D/MT after the twentieth year. This study showed that a few percent (2%) fissile izotopes mixed with thorium would make it possible to run the CANDU reactor.
