Analysis of reusability of ThO2 and spent UO2 fuels enriched with ads in a CANDU reactor

The study presents the analysis of reusability ThO2 and spent UO2 fuels enriched in two different ADS reactors fuelled with Minor Actinide. are taken out from pressurized water reactor CANDU fuels. For this analysis, CANDU-37 having a total fission thermal power 2156 MW is considered 14 cases previous enrichment processes analysed by burning reactor. 3-D time-dependent critical burn up calculations carried using MCNP 2.7 code. To determine effective time each case, these performed until values kinf decrease to about criticality thresh old 1.05 for all investigated cases. percent ages 239Pu 233U fissile isotopes appear be below weapons-grade plutonium uranium, respectively, fuel At end times, burnup can reach varying range 26.770 33.540 GWd/MTU which mean 3.5-4.5 times value fed NatUO2 fuel. results bring that terms energy production, designs demonstrates higher neutronic performance than conventional
