【摘要】 利用RELAP5程序对先进堆二次侧非能动堆芯余热排出系统实验的瞬态过程进行数值模拟。在微循环启动,有注水的工况下,比较了RELAP5程序的计算结果和实验数据,计算结果与实验基本一致。由此可见,利用RELAP5程序分析此类问题是可行的。瞬态计算结果还为先进压水堆非能动余热排出系统的设计提供参考。更多还原

【Abstract】 The paper is to analyze the transient behavior of an experiment of Passive Residual Heat Removal (PRHR) system of advanced PWR secondary side by RELAP5. A comparison between the calculated results and the experimental data shows a good match and the feasibility in dealing with such questions by RELAP5. The results of transient analysis could be considered as a reference for the design of PRHR system in advanced PWR.更多还原
