LWRs use low enriched uranium fuel with similar to 3.5 U-235 whereas CANDU utilizes natural uranium fuel with similar to 0.71 % U-235. In this work, neutronic performance of CANDU reactor, temporal change of fissile fuel breeding and fission power production were investigated in the CANDU reactors with different uranium (UO2, UC, U3Si2) fuels. Calculations were done with the aid of one dimensional computer code of SCALE 4.4a. According to calculational results, by taking k(infinity) = 1.06 as reference limit, burnup grades were found as 7700, 8900 and 7400 MW. D/MT and operation periods were obtained as 170, 260, 190 days for these fuels, respectively. According to these results, UC fuel showed better nuclear performance than natural UO2 and U3Si2 fuel with respect to criticality and burn up grade.trinfo:eu-repo/semantics/closedAccessCANDU reactorsUranium fuelsFissionCriticalityBurn upArticle82147152WOS:000447756900004N/A
