Lifting of Steel Liner Module 1 for Unit 4 of Guangdong Taipingling Nuclear Power Plant Successfully Completed

A key construction milestone was reached at the Guangdong Taipingling nuclear power construction site, where the 2,000-tonne crawler crane of CNNC Machinery Engineering precisely completed the lifting and positioning of Steel Liner Module 1 for Unit 4 of Guangdong Taipingling Nuclear Power Plant. The entire lifting operation lasted 2 hours and 12 minutes, with smooth and orderly lifting, lowering, and slewing movements, and strict control over safety and quality throughout the process, marking the official commencement of main structure construction for the nuclear island reactor building.

As the core barrier of the reactor containment, the steel liner module safeguards the nuclear safety defense line, and modular lifting is also a key technical step in the batch construction of the "Hualong One" reactor. The steel liner module lifted this time integrates the base plate in one formed piece, featuring a large diameter, thin shell wall, and relatively low stiffness. To achieve smooth lifting and positioning, precision control was mandatory, with zero tolerance for deformation deviation.

The project team demonstrated exceptional capability to precisely overcome the challenge:

An integrated truss tooling technology was adopted, and a meticulous dedicated lifting plan was developed based on the component characteristics. Sixteen evenly distributed lifting points were arranged on the truss to disperse forces and balance the module load, fundamentally enhancing the stability and safety factor of the lifting operation.

Through rigorous load calculations and multiple technical reviews, key parameters such as crane positioning, lifting path, and placement angle were repeatedly optimized. Comprehensive joint inspections and simulation drills were conducted prior to the formal lifting, ensuring stability and precision throughout the entire process of hoisting, slewing, and placement of the module.

The project team worked in close coordination with other construction units on site, deeply integrated into the unified collaborative command system, participated in formulating avoidance plans for construction machinery such as tower cranes on site, and designated fully enclosed warning zones, providing comprehensive safeguards for lifting safety and construction quality.

During construction, the project team consistently practiced the work style of "rigorous, prudent, meticulous, practical, swift, and precise": in response to objective factors such as hot summer weather and multi-disciplinary cross-construction on site, team members worked in close collaboration, strictly implementing management systems including pre-lifting joint inspections, proactive risk control, and coordinated morning and evening briefings, weaving a tight safety network throughout the entire process.

As an important project in the batch construction of "Hualong One" reactors in the Guangdong-Hong Kong-Macao Greater Bay Area, CNNC Machinery Engineering will continue to uphold the safety philosophy of "safety first, absolute certainty," and with professional, safe, and reliable lifting and transportation services, fully ensure the smooth progress of "Hualong One" unit construction, contributing "CNNC Lifting" strength to safeguarding national energy security and promoting green and low-carbon development.
