Communications Division of Rosatom Engineering Division, PUBLISHED 26.06.2023

In the reactor building of Tianwan NPS power unit No. 7, which is being built in China with involvement of the Rosatom Engineering Division, the upper part of the inner containment dome weighing 214 tons and being 36 meters in diameter has been installed in the design position.

The works to install the inner containment dome were carried out in two stages. Earlier, on May 19, the lower part of the dome being 44 meters in diameter and weighing 391 tons, was installed on the containment's cylindrical part in the reactor building. For this end, a crane with a maximum 2000t lifting capacity had been delivered to the construction site.

"The construction of Tianwan NPS Unit 7 is proceeding right on time. The next step will be to install the key equipment inside the reactor building, i.e. the reactor pressure vessel, steam generators, hydraulic tanks of the emergency core cooling system, pressurizer, main circulation pumps," said Alexey Bannik, Atomstroyexport JSC Vice President for Projects in China and Prospective Projects.
