三门核电厂AP1000核电机组凝汽器采用模块化安装，因此在设计、供货和安装等方面具有不同于一般核电机组的特点。针对模块化安装的难点，阐述了该工程凝汽器的模块化供货、吊装、拖运、就位等安装工艺，可供同类核电工程凝汽器安装参考。

Sanmen AP1000 NPP is different from the general nuclear power units in design, supply and installation due to the application of condenser modular installation. According to the difficulty of modular installation, this paper introduced the installation process, such as supply, hoisting, emplacement and so on, which could provide references for other condenser installation projects in NPP.
