摘　　要：修改并验证了分析程序FEMAXI-IVM,增加了程序的适用范围。对采用M5合金包壳的FA300-4高性能燃料组件中的燃料棒在稳态和瞬态运行工况下的燃料性能进行了分析。结果表明,此种燃料棒在稳态和瞬态工况下都能保持其完整性,能保证反应堆的安全运行。The steady and transient performance analysis for the fuel rods in FA300-4 fuel assembly with M5 alloy cladding has been performed. Performances of the fuel rods have been analyzed, including temperature of the fuel and cladding, and stress and strain, inner pressure and corrosion of the cladding, etc. In order to do the analysis, the performance analysis code （FEMAXI-IVM） has been modified. The results show that analysis for fuel rods of FA300-4 fuel assembly with M5 alloy cladding can be conducted under steady and transient conditions, so the integrality of the fuel rods and safety of the reactor are ensured.
