摘　　要：为了对铅基快堆氧化物燃料元件稳态工况下的服役性能和行为演化进行模拟计算,本文基于串行的半隐式耦合求解方法开发了铅基快堆氧化物燃料性能分析程序FUTURE。程序采用两步分析法实现了铅基快堆氧化物燃料棒全域热力分析与局部行为模型的多物理场耦合计算。通过各计算模块与模型算例、基准公式和现有程序的对比分析,对FUTURE程序进行了各分离效应的初步验证。结果表明,FUTURE程序能准确模拟铅基快堆稳态工况条件下氧化物燃料元件内部的温度演化、结构变形、应力分布和相互作用,并实现对燃料重构、氧和钚元素的迁移、裂变气体释放和服役期内液态铅铋腐蚀等内容的计算模拟。To simulate and analyze the performance and behaviors evolution of oxide fuel for lead-based fast reactor under steady operating condition,the fuel performance analysis code FUTURE was developed based on the semi-implicit coupling solution method.This code adopted a two-step analysis method to achieve the coupling calculation of the global thermomechanical analysis and the local behavior models of the oxide fuel element on the lead-based fast reactor.Through the comparison of each calculation module with the related model examples,the benchmark formula and the existing similar codes,FUTURE code was preliminarily verified and tested all separate effects.The comparison result indicates that FUTURE code can accurately simulate the temperature evolution,structural deformation and stress distribution inside the fuel element,and achieve the computational simulation of fuel restructuring,oxygen and plutonium migration,fission gas release and liquid lead-bismuth corrosion during steady-state operating.
