AC600二次侧非能动余热排出系统液柱启动自然循环过渡特性研究

Study on Liquid Head Start up Natural Circulation Transition of AC600 Secondary Side Passive Residual Heat Removal System

进行了空气冷却器放置方式、系统冷热芯高差、系统阻力、空气冷却器出口温度及下降段液位对液柱启动自然循环过渡过程特性影响的实验，并进行了分析讨论。实验结果分析表明：该启动方式是可行的，但其过渡特性与空气冷却器放置方式、系统冷热芯高差、系统阻力、空气冷却器出口温度及下降段液位等因素有关。

Investigation on liquid head start up natural circulation transition characteristic of AC600 secondary side passive residual heat removal system is presented. The paper deals with the experimental research and analyze the affecting factors,such as various position of air cooler,the height of system cold heat core,system resistamce,system pressure,air cooler outlet temperature and liquid head of down section.It shows that the start up mode is feasible,but its transition characteristic is affected by following factors:various position of air cooler,the height of system cold heat core,system resistamce,system pressure,air cooler outlet temperature and liquid head of down section.
