秦山核电厂调试期间一回路的水质控制

为尽量减少秦山核电厂一回路系统设备的腐蚀,以及减少冷却剂循环污染和降低一回路系统的放射性,在冷态试验和热态功能试验阶段,堆装料、启动和功率运行试验阶段,都进行了一回路水质控制。本文介绍了一回路水质控制方法,并着重介绍了冷却剂的pH值、氯离子、溶解氧、溶解氢的控制以及硼与锂的协调。秦山核电厂的调试获得令人满意的成功,一回路水质控制也是卓有成效的。

Primary Water Quality Management During Commissioning for Qinshan NPP

This paper describes Qinshan NPP primary water managment main items and control methods to decrease corrosion of primary system facilities, to ensure reactor safe and economical operation, and to drop contamination of reactor coolant cycle and acticity level of primary system during cold trial, hot functional tests, initiaol fueling, starp up, power operation periods and so on. It lays on emphasis on the research of pH value, chloride, dissolved oxygen, dissolved hydrogen and coordinated boron / lithium treatment in reactor coolant, Satisfying results of commisioning in Qinshan NPP have been achieved. Control of primary water aualitv has been also Derformened successfullv.
