Concrete pouring completed for turbine deck of conventional island of Unit 2 at CGN Lufeng Nuclear Power Plant

At 12:30 on August 11, 2026, concrete pouring officially commenced for the turbine deck of the conventional island of Unit 2 at CGN Lufeng Nuclear Power Plant, and was successfully completed at 16:00 on August 13, after 51.5 hours, with a total of 2,685m³ of concrete poured.

The turbine deck structure of the conventional island of Unit 2 measures 68.7m in length and 16m in width, with a top elevation of +8.43m, consisting of two longitudinal beams and six transverse beams. Owner-supplied items include 296 anchor bolts, 56 lifting columns, 28 anchor plates, and 18 oil pipe sleeves, among which 8 sets of large embedded parts weigh over 10t each. The turbine deck construction features complex structures, a large number of owner-supplied embedded parts, and high precision requirements.

During the turbine deck construction, the project team fully drew on the experience feedback from the conventional island turbine deck of Unit 1, optimizing construction processes and organization. For high-precision embedded parts such as bolts with a permissible horizontal deviation of 2mm and anchor plates with a permissible deviation of 3mm, the on-site team adopted a "integrated steel frame support + bottom-support and top-suspension composite fixation" method to ensure that embedded part deviations remained within allowable limits. Facing the challenge of Typhoon "Hongxia," the team conducted a comprehensive inspection of typhoon prevention measures, including slope and foundation pit drainage, drainage pump capacity in the foundation pit, and protective sheds and operating platforms, ensuring the safety and reliability of the construction work surface.

The successful completion of concrete pouring for the turbine deck of the conventional island of Unit 2 creates favorable conditions for the subsequent overall turnover of the turbine foundation for installation. Looking ahead, Lufeng Nuclear Power will continue to deeply practice the work style of "rigorous, prudent, meticulous, and practical," adhere to the value orientation of "three focuses," and make every effort to promote the high-quality construction of Units 1 and 2.
