AP1000核电站CB20模块组装技术探讨

摘要

CB20模块位于反应堆屏蔽墙上部,构成PCS(非能动安全壳冷却系统)系统水箱,其形状为梯形的桶形结构,是多部件组合体,外型尺寸大、结构复杂.本文就CB20模块的组装技术进行探讨,以期为后续类似工程提供借鉴经验.%Module CB20 is located above Reactor Shield Building wall,constituting PCS(Passive Containment Cooling System)water tank.It is a trapezoidal barrel assembly of multi components with large size andcomplex structure.In this paper,the assembling technology of module CB20 is discussed so as to provide experience for subsequent similar projects.
