基于搭建于MOOSE 三维有限元计算平台的燃料元件性能分析程序,通过对燃料棒稳态工况下芯块中心温度分析,完成UN/U3Si2-FeCrAl 燃料棒的概念设计,给出相对于传统UO2-锆合金燃料系统,综合性能更优、安全性良好的燃料元件初步设计方案。
Based on the fuel element performance analysis program built on MOOSE 3D finite element computing platform, the conceptual design of UN/U3Si2-FeCrAl feul rods was completed by analyzing the core temperature of the pellets under the steady working condition. Compared with the traditional UO2-zirconium alloy fuel system, the preliminary design scheme of fuel elements with better comprehensive performance and good safety was given.
