ROSATOM announced that IC dome metal structures were installed in the reactor building of Power Unit 2 at the Rooppur NPP construction site Bangladesh. The upper portion of the dome weighing 194 tonnes and being 35.7 meters in diameter was placed in its design position at an elevation of 51.7 meters and the construction height has now reached 60.5 meters.Installation activities for the IC dome were conducted in two stages. The lower portion of the dome weighing 195 tonnes and being 42.8 m in diameter was placed in its design position a week earlier, on 20 June.Assembly and installation activities for the IC dome are carried out by specialists of the Branch Office of TrestRosSEM LLC (comes under the Rosatom’s Engineering Division). The Liebherr LR11350 crane (with a lifting capacity of 1350 tonnes) was used to make a lift which took 4 hours. There was a particular difficulty in the process since it was required to place both dome portions in the design position with a tolerance of not more than 1 cm.The inner containment is one of the main components of the nuclear power plant safety system. It not only protects the reactor compartment, but also supports the polar crane used to service the nuclear reactor.The Rooppur NPP with two VVER-1200 reactors and a total capacity of 2400 MW is being constructed under a Russian design 160 km of Dhaka, the capital of Bangladesh, in accordance with the General Contract of 25 December 2015.
