AP1000核电站CA20大型结构模块组装技术探讨

摘要

Large module assembly is critical and difficult in AP1000 nuclear power unit modularization construction, and CA20 structural module is the first module to be put in place in AP1000 nuclear island and it is a typical large-scale structural module with large dimension and heavy weight. This paper mainly introduces the assembly process of one Nuclear Power Plant 1#NI CA20 structural module and analyzes its emphases and difficulties, which provides reference and guidance for AP1000 nuclear power unit modularization construction in the future.%大型模块组装是AP1000核电机组模块化施工的重点难点，CA20结构模块是AP1000核岛中第一个就位的模块，其尺寸大、重量重，是典型的大型结构模块。本文主要介绍某核电站1#核岛CA20结构模块组装过程，分析其重点和难点，为以后AP1000核电机组模块化施工提供借鉴和指导。
