摘要
归纳了核电机组中常见的循环水泵与凝汽器的配置方式,分析了各种配置方式对机组运行的影响。在极端情况下,需考虑单台或多台循环水泵突然停运时,对凝汽器背压产生的影响。如果某台循环水泵停运,将改变凝汽器的运行状态,并产生瞬时压力差,同时,给系统的安全运行带来隐患。
The configuration mode of circulating water pump and condenser in nuclear power unit was summarized and the influence of various configuration modes on the operation of the unit was analyzed in this paper. In the extreme situation, the single or multiple circulating water pump is suddenly stopped and impact on the back pressure of the condenser, which must be considered. If a circulating water pump is stopped, the operation state of the condenser will be changed, and the instantaneous pressure difference will be generated, and the system safe will be infected.
