At 5:08 p.m. on August 30, 2024, the first phase of's nuclear power project in Lianjiang, Guangdong Province, ushered in an important milestone: the CA03 module, the core component of Unit 1, was successfully hoisted and placed in its intended position after careful planning and close collaboration. The operation, carried out by a powerful 3,600-ton crawler crane, was like a skilled dancer, and went through complex and delicate steps such as lifting, stable hovering, precise rotation, smooth landing and fine-tuning, laying a solid foundation for the internal construction of the nuclear island reactor plant.

The whole hoisting process took 2 hours and 41 minutes, and the whole process showed a high degree of safety, order and controllability. The CA03 module, as the southwest steel wall structure of the internal replacement water tank, is particularly unique in its structure, which is spliced by up to 17 precision sub-modules, forming a spectacular C-shaped semi-circular arc barrier, with a total weight of 339.5 tons and a total weight of 339.5 tons, all of which pose extremely high challenges to the hoisting technology. The module is not only bulky, but its semi-arc design increases the difficulty of azimuth adjustment in the hoisting process, which may lead to deformation if you are not careful, and at the same time, the environment of the in-place area is complex, and the steel bar is dense and the space is limited, which further aggravates the risk and difficulty of the operation.

In order to overcome these difficulties, the Shanghai Nuclear Engineering Institute has adopted a number of innovative measures: anti-deformation tooling has been specially added for deformable areas to strengthen structural stability; The wire rope is used to bind the module in an all-round way, and with the help of ground forklift traction, the precise control of the module direction is realized; In addition, advanced technologies such as large-space 3D laser scanning, BIM modeling and reverse engineering have been introduced, and the integration and application of these high-tech means is like installing a smart brain for hoisting operations, ensuring that the CA03 module can be seated in the predetermined position without any difference.

In the end, with the tacit cooperation and unremitting efforts of the hoisting team, the contest of technology and courage ended in victory, and the CA03 module successfully and successfully completed the hoisting task, laying a solid road for the follow-up construction of Guangdong Lianjiang Nuclear Power Project.Editor/Jiang Mingyue
