On June 18, 2024, the dome has been successfully lifted and installed at a single stage on the reactor building of Xudapu NPS power unit No. 4 (China) constructed with involvement of the Rosatom Engineering Division. Previously, was installation was carried out in two stages during construction of NPSs of Russian design.
For the first time such an operation was carried out in July 2023, at Unit 3 of the same NPS. The mature technology ensures a significant reduction in the construction time of the power unit.
“Unlike the traditional installation of the dome in two stages, the one-stage lifting technology significantly streamlines the process and reduces the time of this work. The 740-ton dome pre-assembled on the ground was lifted by crane on the reactor building. The reactor vessel is still to be installed at Unit 4, said Alexey Bannik, Atomstroyexport JSC Vice President for projects in China and prospective projects.
The polar crane was previously installed at the site, and this will help installing large-sized equipment after the installation and concreting works have been completed inside and outside the dome part of the reactor building.
