摘　　要：本文选取主流的CPR1000、WWER-1000和AP1000三类百万千瓦级压水堆核电厂的化容系统,对其在执行容积、化学和反应性方面的控制模式进行分类说明,寻找各自在化学添加、设备布置、可靠性设计等方面的特点。通过比较分析,展现出各类化容系统的优势和不足之处,突出展现AP1000化容系统基于非能动和“做减法”的设计理念,最后借鉴其他化容系统,给出了CVS系统的改进意见。In this paper,it selects three types of chemical and volume control systems on mainstream PWR nuclear power plants including CPR1000,WWER-1000 and AP1000.Firstly it describes the control modes of these systems in the volume,chemical and reactivity controls.Then,it finds out their own characteristics in chemical adding,equipment layout and reliability design.Through comparative analysis,it shows the advantages and disadvantages of various chemical and volume systems,and highlights the design concept of AP1000 chemical and volume system based on passive and"subtraction".Finally,based on other chemical and volume systems,the improvement suggestions of CVS system are given.
