8月17日，在经历开箱检查、场内运输、吊装至17.5m平台、容器内部检查、翻转平移等工作后，三澳核电项目2号机组反应堆压力容器顺利就位，全程历时14天，标志着2号机组主设备安装进入新的阶段，为后续主管道焊接、主泵安装等工作奠定了坚实基础。

反应堆压力容器重约300吨，是核反应发生的核心设备，被誉为核电站的“心脏”。压力容器主要负责固定和支撑堆内构件，确保燃料组件按一定的间距在堆芯内的支撑与定位，限制核反应在其内部进行。

苍南核电、中广核工程苍南项目部、监理单位和中核二三三澳核电项目部共同成立党员联合攻坚队。在准备阶段，攻坚队全面落实经验反馈，进行安全质量技术交底，组织开展专项检查。在实施阶段，攻坚队合理安排施工作业，严格控制施工过程中的安全和质量。最终在各参建单位积极沟通、通力协作下，实现反应堆压力容器引入全过程安全质量可控。

On August 17, after unpacking inspection, on-site transportation, lifting to 17.5m platform, internal inspection of the vessel, flipping and translation, the reactor pressure vessel of Unit 2 of the Sanao Nuclear Power Project was successfully installed, which lasted 14 days, marking the installation of the main equipment of Unit 2 into a new stage, laying a solid foundation for the subsequent main pipeline welding and main pump installation.

The reactor pressure vessel, weighing about 300 tons, is the core equipment for nuclear reactions and is known as the "heart" of nuclear power plants. The pressure vessel is mainly responsible for fixing and supporting the inner components of the reactor, ensuring the support and positioning of the fuel assembly in the core at a certain distance, and limiting the nuclear reaction in its interior.

Cangnan Nuclear Power, Cangnan Project Department of Cangnan Nuclear Power Project, supervision unit and CANGnan Nuclear Power Project Department jointly established a joint team of Party members. In the preparation stage, the team fully implemented the experience feedback, carried out safety and quality technology disclosure, and organized special inspections. In the implementation phase, the assault team rationally arranged the construction work and strictly controlled the safety and quality of the construction process. Finally, under the active communication and cooperation of all participating units, the safety and quality control of the whole process of introducing the reactor pressure vessel is realized.
