en.Wedoany.com Reported - At 8:02 a.m. on June 15, 2026, the dome of Unit 5 at the Ningde Nuclear Power Plant of China General Nuclear Power Group (CGN) in Fujian Province was successfully lifted into place. The dome, with a diameter of approximately 45 meters and a weight of over 270 tons, was hoisted by the XGC28000, a 2,000-ton crawler crane independently developed by XCMG. After 2 hours and 45 minutes of continuous operation, the dome was precisely positioned in a single attempt. This lifting marks the official transition of the "Hualong One" nuclear power unit from the civil construction phase to the equipment installation phase.

The XGC28000 crawler crane is a large-scale lifting equipment independently developed by XCMG, with a rated lifting capacity of 2,000 tons and a rated lifting torque of 27,459 kilonewton meters (2,800 ton-force meters). It features a split crawler chassis and a multi-combination truss boom, offering advantages such as low ground pressure, the ability to travel with a load, and a large lifting height. During this lifting operation, the XGC28000 used a 108-meter heavy-duty main boom, and the entire process—from vertical lifting to aerial rotation, from traveling with a load to high-altitude adjustments—was stable and precisely controlled. In addition to the main lifting equipment, 10 XCMG tower cranes, including the XGT2230-100S (100-ton class), participated in the operation, handling high-altitude, large, and heavy equipment lifting tasks in the nuclear island and conventional island areas. This lifting marks the second time the XGC28000 has undertaken a critical lifting task for a "Hualong One" nuclear power unit, following its role in the dome lifting of the No. 3 reactor building at the Fangchenggang Nuclear Power Plant in 2018.

The Ningde Nuclear Power Project, located in Ningde City, Fujian Province, is an important clean energy base along the southeastern coast of China and the first nuclear power project in Fujian Province to commence construction and enter operation. The project plans to build six million-kilowatt-class nuclear power units in two phases. The first phase, consisting of four units, was fully completed and put into operation in 2016. As of the end of March 2026, the cumulative on-grid electricity generated by the first-phase units exceeded 347 billion kilowatt-hours. The second phase, Units 5 and 6, adopts China's independently developed third-generation nuclear power technology, "Hualong One," with a construction period of 54 months per unit. The main construction of Unit 5 officially began on July 28, 2024. Following the successful dome lifting, Unit 5 will enter the equipment installation and commissioning phase, laying the foundation for subsequent grid connection and power generation. Once Units 5 and 6 of the Ningde Nuclear Power Plant are completed, they will further enhance the clean energy supply capacity of China's southeastern coastal region.
