摘　　要：为实现RELAP5热工水力程序在重水堆全堆范围内瞬态模拟,在RELAP5源程序中添加轻重水混合后工质的物性计算模型、调用逻辑以及流体选择结构,增加各个控制体内任意时刻的重水份额计算程序,同时,优化针对重水堆水平压力管的流动换热关系式及CHF模型。结果表明,程序改造与预期符合较好。因此,基于RELAP5程序开发的重水堆模拟程序能够用于重水堆全堆模拟计算,可为重水堆运行工作的研究提供理论支撑。In order to realize the transient simulation of RELAP5 thermal hydraulic program in the whole range of heavy water reactor,this paper adds the physical property calculation model,call logic and fluid selection structure of working medium after light and heavy water mixing in the RELAP5 source program,increases the calculation program of heavy water share in each control body at any time,and optimizes the flow and heat transfer relationship and the CHF model for the horizontal pressure pipe of heavy water reactor.The results show that the program modification is in good agreement with the expectation.Therefore,the heavy water reactor simulation program developed based on RELAP5 can be used for the whole reactor simulation calculation of heavy water reactor,it can provide theoretical support for the researoh of heany water reactor operation.
