The 740-ton dome was lifted and installed in one stage on the reactor building of power unit No. 4 of the Xudapu NPP (Huludao City, Liaoning Province) in China. The nuclear facility is being built with the participation of the Engineering Division of Rosatom State Corporation. Previously, during the construction of a Russian-designed NPP, the dome installation took place in two stages.
The single-stage lifting technology optimizes the process and reduces the time of work. The dome, assembled on the ground, was lifted by a crane and placed on the reactor building. Ahead, unit No. 4 is waiting for the installation of the reactor vessel.
A polar crane was also installed at the construction site. After the completion of concrete works inside and outside the dome part of the reactor building, the crane will be needed for the installation of large-sized equipment.
Xudapu NPP is a new project of Rosatom and Chinese CNNC in the field of nuclear energy. In 2019, the parties signed contracts for the construction of power units No. 3 and No. 4 of the Xudapu NPP with VVER-1200 reactors. Russia will also supply nuclear fuel to China. The commissioning of power units is scheduled for 2027-2028.
