0引言三门核电一期工程是国家引进AP1000核电技术自主化依托项目之一,其中一号机组为世界首个AP1000核电机组。AP1000是第三代核电技术,具有先进的非能动安全设计和模块化建造技术的鲜明特点,作为世界上首次开工建造的三门核电一期工程没有参考电站和成熟经验可以借鉴,其一号机组核岛筏基混凝土浇筑(简称FCD)是标志工程建设的第一个重大里程碑,是核岛开工建造的首个专项工程。
0 Introduction The first phase of Sanmen Nuclear Power Project is one of the projects relying on the country’s introduction of the AP1000 nuclear power technology autonomy, of which No. 1 is the world’s first AP1000 nuclear power unit. AP1000 is the third generation of nuclear power technology, with advanced passive safety design and modular construction technology distinctive features, as the world’s first construction of the three nuclear power plant without reference to the power station and mature experience can learn from, the first unit The nuclear island raft concrete pouring (FCD) marks the first major milestone in the construction of the project and is the first special project to start the construction of the nuclear island.
