摘要
本文采用简便实用的微机化数学模型,选用解刚性方程组很有效的 STIFF 数值积分法,编制了计算失热阱下池式钠冷快堆主回路系统动态过程的程序 WPRMY1。该程序可在微机上运行,对 EBR-Ⅱ 两个失热阱瞬态的计算结果,与国外大型程序 NATDEMO 的相应计算值以及可获得的部分试验数据符合良好。
In this paper,a simple but effective mathematical model forthe primary system of a pool-type FBR was constructed.Basedon this,a dynamic simulation program for LOHS transient,WPRMY1,was developed after the choice of an explicit nonli-near integration method STIFF.It was used to compute twoLOHSWS test transients of EBR-Ⅱ.The results are very goodin agreement with the predicted results of a large programNATDEMO and the measured data.
