Module III of the steel liner of the nuclear island containment vessel for Unit 1 of the Jiangsu Xuwei Nuclear Heating and Power Plant was hoisted into place

On September 15, good news came from the construction milestone of Unit 1 of the Jiangsu Xuwei Nuclear Heating and Power Plant — the first nuclear power unit to start construction during China's 15th Five-Year Plan period — as Module III of the steel liner of the nuclear island containment vessel was successfully hoisted into place, marking another key progress in the project's main construction. Module III hoisted this time adopted a two-layer cylindrical wall panel assembly structure, with a module dead weight of 133 tonnes, an overall lifting weight of 258.52 tonnes, a module body height of 11 meters, and a hoisting elevation of 15.75 meters. As the module landed smoothly in place, the already installed Module I and Module II were connected with Module III as one integrated unit, bringing the cumulative overall height of the containment vessel steel liner cylinder to 31.45 meters. The containment vessel is the core safety barrier of the nuclear island, and the steel liner...

Module 4 of Steel Liner for Unit 3 of San'ao Nuclear Power Plant Successfully Hoisted

At 8:16 a.m. on August 15, the hoisting operation of Module 4 of the 3BRX steel liner for Unit 3 of the San'ao Nuclear Power Plant was officially launched. Under the stable operation of the 2,000-ton crawler crane of CNNC Machinery Engineering, the module successively completed a series of procedures including slewing, load-bearing travel, and alignment adjustment. After 220 minutes, the hoisting task was successfully completed. Module 4 of Unit 3 hoisted this time was integrally assembled from the fourth and fifth layers of the cylinder, with a diameter of approximately 45 meters and a height of 11.46 meters. The module features a large volume, susceptibility to deformation, and limited slewing space for the crane. The project team strictly implemented the special plan, completed site reinforcement, transport of baskets and counterweights, and crawler crane relocation in advance, organized hoisting simulation drills, and comprehensively inspected various safety hazards...

Module 5 of Containment Steel Liner Successfully Lifted at Unit 3 of Guangdong Taipingling Nuclear Power Plant

On August 10, the construction of Unit 3 at CGN's Guangdong Taipingling Nuclear Power Plant reached a critical milestone. A Zoomlion 2,000-tonne crawler crane, serving as the core lifting main force, successfully completed the precise positioning of Module 5 of the containment steel liner. This lifting operation involved significant technical challenges and demanding working conditions. The steel liner Module 5 weighed nearly 280 tonnes, with a component diameter of 45 meters, a height of nearly 6 meters, and a wall thickness of only 6 millimeters, making it a typical ultra-large thin-walled flexible component. The module's lateral windward area exceeded 300 square meters, making it susceptible to wind-induced sway during lifting, which imposed extremely high requirements on the crane's operational stability, control precision, and heavy-load adaptability. The Zo...

First Integrated Hoisting of Nuclear Island Steel Liner Module 5 with Attached Electrical and Instrumentation Cable Tray System within CGN

At 15:30 on August 10, 2026, with the successful positioning of Steel Liner Module 5 in the reactor building of Unit 3, the attached electrical and instrumentation (E&I) cable tray system was simultaneously placed, marking the successful completion of the first "Five-ization" installation project for Module 5 attached E&I cable trays within China General Nuclear Power Group (CGN). Traditional nuclear power Module 5 construction adopts a serial mode of "structure first, installation second, commissioning last." The E&I construction for Module 5 of Unit 3 at Taipingling Phase II innovatively adopted an integrated scheme of "prefabrication-installation-integral hoisting." E&I construction was advanced to the module assembly stage, changing the traditional on-site dispersed work method. Through prefabrication of steel materials in workshops, delivery to the site for welding and installation, a large amount of high-altitude, cross-operational...

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 Hualong One reactors. 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...
