en.Wedoany.com Reported - The second ring of the steel containment vessel (hereinafter referred to as "CV") for Unit 1 of the Lufeng Nuclear Power Plant, manufactured by State Nuclear Power Equipment Manufacturing Co., Ltd., was smoothly transported to the designated position of the nuclear island at 10:10 on June 7, and the overall hoisting and installation was successfully completed at 10:26 on June 8. The entire process was stable and orderly, with safety and quality fully under control.
The second ring hoisted this time is the third lifting section of the CV. Its lower opening connects to the upper opening of the first ring of the CV. The second ring has a maximum diameter of approximately 40m, a height of about 8m, and a total hoisting weight of approximately 763t. It mainly consists of more than 20 shell plates, attachment plates, and internal stiffeners, and is a core component of the nuclear island containment vessel.
During the assembly and construction phase of the CV second ring, the Lufeng site project team scientifically coordinated the construction schedule, insisted on holding daily special meetings, and systematically identified and resolved on-site construction bottlenecks and difficulties. The special hoisting plan was strictly prepared and reviewed, and the full-process on-site control measures were refined to ensure the one-time precise hoisting and installation of the CV second ring. Adhering to the principle of "maximizing modularization and applying it wherever possible," the project team, in collaboration with civil engineering and installation units, simultaneously carried out multi-disciplinary construction operations such as process piping, SPLsteel structure, electrical supports, and cable trays at the assembly site. This continuously deepened the application of modular construction, effectively mitigating the constraints of the construction environment in the nuclear island area and significantly improving construction efficiency.
In the next step, State Nuclear Power Equipment Manufacturing Co., Ltd. will continue to serve the construction of major national energy projects, fully leverage the guiding role of Party building and professional support, and coordinate the advancement of key tasks such as on-site construction, quality and safety, and modular construction. It will work together with all participating units to consolidate efforts and overcome challenges, contributing greater strength to the high-quality construction of the Lufeng Nuclear Power Plant project.
