Abstract: The thermal conductivity is one of the most important parameters in the computer code for performance prediction for fuel rods. Several fuel thermal conductivity models used in foreign computer code,including thermal conductivity models forMOx fuel and UO,fuel were introduced in this paper.Thermal conductivities were calculated by using these models,and the results were compared and analyzed.Finally,the thermal conductivity model for the native computer codefor performance prediction for fuel rods in fast reactor was recommended.
Key words: performance prediction; thermal conductivity; fast reactor
燃料元件性能分析程序可以对燃料和包壳的重要特性随辐照时间的演变加以追踪,预言燃料元件在运行工况下的性能。在燃料芯块的高温和高燃耗运行工况下,燃料热导率决定着裂变能量的传输性能、决定着燃料中心的最高
