英文摘要	Producing medical radionuclide Mo-99 in molten salt reactors is a very attractive choice to solve its global shortage. In this study, we evaluated the yield of Mo-99 in the small modular thorium based molten salt reactor (SM-MSR). Firstly, the fuel burn-up analysis of SM-MSR was carried out by an in-house developed code (MOBAT), which takes the unique characteristics of molten salt reactor into account, and the variation of fission yield of Mo-99 with burn-up time was obtained. The minimum value of the fission yield of Mo-99 is 1.13 x 10(-3) (6-day TBq/MW/s) at approximately 600 equivalent full power day. Then, based on the behavior of noble metals in the fuel salt and the experimental results of MSRE gas sample composition measurements, Mo-99 migration probability from the primary loop to the off-gas module with the burn-up time was calculated, and the equilibrium value of the migration probability is obtained as 18.4%. When the load factor of SM-MSR is 0.75 (300 MWth), the annual 99Mo amount of migration to the off-gas module would be 1.96 x 10(6) (6-day TBq) under the most conservative calculation. Finally, a filter system was added in the off gas module, and Mo-99 would be extracted from the off gas. As long as the utilization percentage of Mo-99 in the off gas module can reach 0.94%, the global demand under current data could be met, which implies a huge additional economic value for the SM-MSR.
