AbstractAccelerator-driven systems based on molten salt fuel have several unique advantages and features for advanced nuclear fuel utilization. The aim of this work was to study the Th-U breeding capability in such systems, known as "accelerator-driven subcritical molten salt reactors" (ADS-MSRs). Breeding capacities including conversion ratio and net U-233 production for various subcriticalities and different minor actinides (MA) loadings were analyzed for an ADS-MSR. The results show that the subcriticality of the core has a considerable effect on the Th-U breeding. A high subcriticality is favorable to improving the conversion ratio, increasing the net( 233)U production, and reducing the doubling time. Specifically, the doubling time for k(eff) of 0.99 is larger than 80 years, while the counterpart for k(eff) of 0.93 is only approximately 22 years. Nevertheless, in an ADS-MSR with a high initial MA loading, MA results in a non-negligible 233 U depletion in the first two decades, while increasing the net U-233 production compared to reactors without MA loading. During the 50 years of operation, for the subcritical reactor (k(eff) = 0.97) with MA fraction increasing from 1 to 14% , the net U-233 production increases from 3.94 to 8.24 t.
