6月25日，三澳核电项目2号机组首台蒸汽发生器经过滚转、牵引、翻转等一系列复杂工序后平稳就位于3号蒸汽发生器隔间，至此，2号机组核岛首台主设备引入工作顺利完成，为后续两台蒸汽发生器的引入和安装工作奠定了良好的基础。

三澳核电项目每台机组有三台蒸汽发生器，每台蒸汽发生器净重390吨，长约21米，直径4.6米，是核岛内重量最大、体积最大的主设备。它负责将堆芯产生的热量传递给二回路的冷却水，使之转化为饱和蒸汽，推动汽轮发电机将能量最终转化为电能。

在蒸汽发生器到货前，苍南核电联合监理单位、中广核工程苍南项目部和中核二三公司三澳核电项目部成立党员联合攻坚队，统一目标、加强协作。在准备阶段，项目团队开展首台主设备引入前专项检查，仔细核实先决条件，进行安全质量技术交底。在实施阶段，各单位通力协作，联合攻坚，合理安排施工作业，严格控制施工过程中的安全和质量，共同解决限制主设备引入的疑难问题，最终顺利完成首台蒸汽发生器的引入工作。

On June 25, the first steam generator of Unit 2 of the Sanao Nuclear Power Project was smoothly located in the No. 3 steam generator compartment after a series of complex processes such as rolling, traction, and flipping, so far, the introduction of the first main equipment of the nuclear island of Unit 2 was successfully completed, laying a good foundation for the introduction and installation of the subsequent two steam generators.

Each unit of the Sanao Nuclear Power project has three steam generators, each steam generator net weight of 390 tons, about 21 meters long, 4.6 meters in diameter, is the largest weight and volume of the main equipment in the nuclear island. It is responsible for transferring the heat generated by the core to the cooling water of the secondary loop, so that it is converted into saturated steam, driving the turbine generator to convert the energy into electricity.

Before the arrival of the steam generator, Cangnan Nuclear Power joint supervision unit, Cangnan Project Department of CGN Nuclear Engineering and three Australian Nuclear Power project Department of CNN No. 2 and 3 Company set up a joint team of Party members to unify goals and strengthen cooperation. In the preparation stage, the project team carried out a special inspection before the introduction of the first main equipment, carefully verified the prerequisites, and carried out safety and quality technical disclosure. In the implementation stage, all units work together, jointly tackle difficulties, rationally arrange construction operations, strictly control the safety and quality of the construction process, jointly solve the difficult problems limiting the introduction of the main equipment, and finally successfully complete the introduction of the first steam generator.
