At the Rooppur NPP construction site in the People's Republic of Bangladesh (the general designer and general contractor being ROSATOM’s Engineering Division) the concreting work started at the inner containment dome of the reactor building at power unit No. 2.
The work is being carried out by specialists of the Trest RosSEM LLC branch (that is part of ROSATOM’s Engineering Division). It is planned to lay more than 3,200 cubic meters of concrete on the 17.6m high reinforced concrete structure and the 42.8m base diameter using four concrete placement booms.
“The final stage of building the passive safety system has just started. We will be able to optimize the concreting process by replicating the experience gained in performing similar work, in the reactor building at Power unit 1”, commented Alexei Deriy, ASE JSC Vice President - Director of the Rooppur NPP construction project.
For reference:
The inner containment is one of the key elements of the nuclear power plant safety system. It protects the reactor compartment and supports as well pipeline penetrations and the polar crane, with which the nuclear reactor is serviced.
Rooppur NPP equipped with two VVER-1200 reactors of the total 2400 MW capacity is being constructed under the Russian design 160 km from Dhaka, the capital of Bangladesh, in accordance with General Contract dated December 25, 2015. The Russian design with VVER-1200 reactors was selected for the first NPP in Bangladesh, which was successfully implemented at two units of the Novovoronezh NPP. This is an evolutionary Generation III+ design which fully complies with all the international safety requirements.
