摘要
本文结合点堆动力学方程、非稳态传热方程和线弹性运动微分方程,开发了适用于金属核燃料系统的瞬态特性分析程序STAC。利用STAC程序对美国Godiva-Ⅰ瞬态实验装置进行了模拟,得到了该装置的裂变率、反应性和温度随时间的变化。STAC程序计算结果与Godiva-Ⅰ装置的实验结果较为一致,验证了STAC程序的准确性。
A transient code STAC was developed based on one‐point kinetic equation , thermal conduct equation and linear elasticity equation for the purpose of analyzing nuclear metallic fuel system .The prompt super‐critical experiment on Godiva‐Ⅰ device was simulated by using STAC code ,in which the changes of fission rate ,reactivity and temperature with time were calculated .The simulation results are consistent with the experiment results on Godiva‐Ⅰ device ,which verifies the accuracy of STAC code .
