摘　　要：在线添料及在线去除中子毒物是熔盐堆区别于其他固体燃料反应堆的主要特征之一,能够实现较高的燃耗深度和燃料利用率。然而,现有的反应堆物理计算分析软件SCALE不能直接模拟熔盐堆的燃耗计算。因此,本文耦合SCALE中的截面处理模块、临界计算模块以及燃耗计算模块,开发了一套适用于多流体熔盐堆的添料与后处理系统分析程序MSR-RRS,实现熔盐堆的在线添料、裂变产物在线处理或离线批次处理等模拟功能。基于MSR-RRS对现有的单流熔盐增殖堆和双流熔盐快堆的燃耗性能进行了验证。结果表明,MSR-RRS计算结果与基准模型结果符合较好。MSR-RRS适用于多种堆型、多种燃料循环运行模式。On-line refueling and reprocessing are the two most significant features of molten salt reactor（MSR）,which are beneficial to improve the burnup and fuel utilization efficiency.The SCALE code is a comprehensive modeling and simulation suite for criticality safety,reactor physics,radiation shielding,radioactive source term characterization,and sensitivity and uncertainty analyses.However,it cannot be directly appliedto simulate the burnup of MSR.Therefore,a special multi-fluid MSR refueling and reprocessing system analysis code（MSR-RRS）was developed by coupling the problemdependent cross section processing module,the criticality calculation module and the burnup and decay calculation module in SCALE.MSR-RRS was used to simulate the behaviors of on-line refueling,on-line reprocessing and/or offline reprocessing fission products in MSR.Moreover,MSR-RRS was verified based on the single-fluid molten salt breeder reactor（MSBR）and two-fluid molten salt fast reactor（MSFR）.The results indicate that MSR-RRS has a high accuracy with the benchmarks.In conclusion,MSR-RRS is suitable for various types of MSR and fuel cycles.
