摘　　要：以氨作为二回路p H调节剂的压水堆普遍采用高pH控制,以抑制二回路水汽系统的流体加速腐蚀(FAC);而提高pH会由于氨浓度的升高而使蒸汽发生器排污系统(APG)除盐床树脂使用周期缩短,引发废物增加、运行成本上升和工作量增加等问题。通过秦山第二核电厂APG除盐床的氨化运行试验,分析认为APG除盐床氨化运行是可行的,是缓解高pH和树脂周期缩短冲突的有效途径,并优先考虑2个除盐系列采用一列氨化和一列氢型运行方式。In the pressurized water reactor which uses ammonia to adjust the feedwater pH, the high PH control method is usually used to inhibit the flow accelerated corrosion （FAC） in the secondary system. But the increasing Ammonia concentration will shorten the lifetime of the resin in the steam generator blowdown system demineralizer, which will lead to the increasing of waste, heavy loading, and operation cost. By the ammonia-saturated operation test of the resin in the steam generator blowdown system demineralizer in Qinshan phase Ⅱ, we found that the ammonia-saturated operation is feasible; and it is an effective method to balance the demand of high PH value and the lifetime of demineralizer resin. And we prefer to use 2 demineralize systems together, one with ammonia-saturated operation and another one with hvdrogen operation.
