提出了选择核供热堆钢安全壳及压力容器吊装方法的原则,介绍了大型起重机、双桅杆和固定式龙门吊等 3种吊装方法,并从 3种方法的技术可行性、安全可靠性、工艺成熟性,对厂房结构、土建安装施工、工程进度和投资的影响以及对工程项目管理水平的要求进行了分析比较。 3种吊装方法,不仅适用于核供热堆压力容器的吊装,也适用于沸水堆和高温气冷堆压力容器的吊装,并为各种堆型核电站采用模块化设计与施工提供了多方案的技术储备。
The principle of selecting the containment of containment vessel and pressure vessel for nuclear reactor is put forward. Three kinds of hoisting methods, such as large crane, double mast and fixed gantry crane, are introduced. The technical feasibility, safety and reliability, Maturity, the plant structure, civil installation and construction, project progress and investment impact and the project management level requirements were analyzed and compared. The three kinds of hoisting methods are not only suitable for hoisting of pressure vessels of nuclear reactor but also for hoisting of pressure vessels of boiling water reactors and high temperature gas cooled reactors and provide multi-scheme for modularized design and construction of various reactor nuclear power plants Technical reserve.
