摘要
利用核设计给出的棒位-功率分布及RELAP5/MOD3程序的202表、205卡,得到了在RELAP5/MOD3程序计算过程中堆芯热构件中各轴向节点相对功率份额随棒位的变化关系,成功地在RELAP5/MOD3中实现了变功率分布分析方法,并利用此方法对某反应堆的提棒事故进行了分析。结果表明,由该方法给出的燃料最高温度相对于固定功率分布方法大幅降低。
In this paper, we use the rod-power distribution obtained by the nuclear design and the 202 tables and 205 cards of RELAPS/MOD3 to realize the change of the relative power share of each axial node in the heat of the RELAP5/MOD3. The ＂variable power distribution＂ analysis method is successfully realized in RELAP5/MOD3, and the method is used to analyze the rod withdrawal accident of a reactor. The maximum fuel temperature obtained by this method is significantly lower than the fixed Dower distribution method.
