Concreting has begun on the inner containment dome of the reactor building of unit 2 at the Rooppur NPP under construction in Bangladesh, Rosatom’s Engineering Division has announced. The work is being carried out by specialists Trest RosSEM, part of the engineering division of Rosatom. It is planned to lay more than 3,200 cubic metres of concrete on a reinforced concrete structure with a height of 17.6 metres and a base diameter of 42.8 metres using four concrete distribution booms.
“We have begun the final stage of building a passive safety system. We will be able to optimise the concreting process by using the experience gained during similar work on the reactor building of the first power unit,” commented Alexei Deriy, Vice President of JSC ASE, Director of the Rooppur NPP construction project.The inner containment is a key elements of the NPP safety system, which protects the reactor compartment and also provides support for pipeline penetrations and the polar crane used to service the reactor.
The Rooppur plant is being built by Rosatom on the eastern bank of the Ganges River in Bangladesh’s Pabna district about 160 km northwest of the capital city of Dhaka. It will comprise two VVER-1200 reactors: Rooppur 1 is scheduled to start operating 2023, followed by Rooppur 2 in 2024.
