聚变驱动乏燃料焚烧堆(FDS-SFB)燃料循环动态分析

Dynamic Analysis of the Fuel Cycle of Fusion Driven Spent Fuel Burner Reactor

针对聚变驱动乏燃料焚烧堆FDS-SFB燃料循环系统与一次通过燃料循环系统,利用系统动力学软件Vensim分别建立了这两种循环系统的动态分析模型,并根据假设的三种核电发展情景,分别计算了这两种燃料循环系统的资源需求、乏燃料累积量、钚累积量及次锕系元素累积量。初步计算结果表明:与一次通过式燃料循环系统相比,FDS-SFB燃料循环系统可减少天然铀需求量与乏燃料累积量,减少的程度与核电发展规模相关。

The dynamic models of FDS-SFB fuel cycle and once-through fuel cycle using Vensim have been constructed.The utilization of resources,the amounts of the spent fuel,the amounts of the plutonium and the amounts of the minor actinide of these two fuel scenarios have been calculated based on three different nuclear power development cases.The results show that FDS-SFB fuel cycle can save on the nature uranium resource and reduce the spent fuel accumulation considerably when compared with the once-through cycle.Both of the amounts of the nature uranium and the amounts of the spent fuel could be reduced most in the high nuclear power development case.
