核电站再循环供水系统瞬态流分析

Analysis of Transient Flow in Recycling Water Supply System of Nuclear Power Plant

与国内沿海核电站采用直流循环供水系统有所不同,内陆核电站采用单元制再循环供水系统.直流循环水系统设计中已应用成熟的无阀系统是否可以在内陆核电站应用,需要通过分析停泵水力瞬态过程来确定.通过对无阀系统进行停泵水锤计算,模拟该系统主要设备的工作过程,论证了无阀系统不可以应用于再循环供水系统.

Different from the DC water supply system that the coastal nuclear power plant applies in China, inland nuclear power station applies recycling water supply system based on unit basis. The system with no valve has been applied in the DC water supply system of the coastal nuclear power plants, can the system with no valve be applied in the inland nuclear power plants？ It needs to confirm after analysing the hydraulic transient after stopping pump. Through calculating the water hammer in the system with no valve after stopping pump and simulating the working process of the main equipment in the system, concludes and proves that the system with no valve can not be applied in the recycling water supply system.
