摘要The molten salt fast reactor (MSFR) shows great promise with high breeding ratio (BR), large negative temperature coefficient of reactivity, high thermal-electric conversion efficiency, inherent safety, and online reprocessing. Based on an improved MSFR optimized by adding axial fertile salt and a graphite reflector, the influences of Li-7 enrichment on Th-U breeding are investigated, aiming to provide a feasible selection for the molten salt with high fissile breeding and a relatively low technology requirement for Li-7 concentration. With the self-developed molten salt reactor reprocessing sequence based on SCALE6.1, the burn-up calculations with online reprocessing are carried out. Parameters are explored including BR, U-233 production, double time (DT), spectrum, Li-6 inventory, neutron absorption, and the tritium production. The results show that the Li-7 enrichment of 99.95% is appropriate in the fast fission reactor. In this case, BR above 1.10 can be achieved for a long time, corresponding to the U-233 production of 130 kg per year and DT of 36 years. After 80 years' operation, the tritium production for 99.5% is only about 7 kg, and there is no obvious increase compared to that for 99.9995%.
