In the People's Republic of Bangladesh, construction crews have completed the concrete layering of the the containment dome at the Rooppur nuclear power plant's Unit 1 reactor, Russian plant builder Rosatom has said.
The work was performed by specialists of RosSEM Trust LLC (part of ROSATOM’s Engineering Division). In total, over 3200 cubic meters of concrete were laid in the structure more than 17.6 meters high with the diameter of the foundation of 42.8 meters.
“Concreting of the containment dome is the final stage of construction of the passive safety system. The works at the next stages will include the CPS strands tensioning and the containment testing”, said Alexey Deriy, Vice President of ASE JSC – Director of Rooppur NPP construction project.
The inner containment is one of the main elements of the NPP safety system. It does not only protect the reactor compartment but also provides support to the pipelines penetrations and the polar crane, which is used for servicing the reactor.
Rooppur NPP with two planned VVER-1200 reactors with the total capacity of 2400 MW is being constructed under the Russian design, 160 km from Dhaka, the capital of Bangladesh, in accordance with the general contract dated December 25, 2015.
The project represents the first nuclear plant construction for Bangladesh. The design has been successfully implemented in two power units of Novovoronezh NPP and is fully compliant with the international safety requirements.
