Concreting of the inner containment dome of Unit 1 has been completed at the Rooppur Nuclear Power Plant recently.
Over 3200 cubic meters of concrete was laid in the structure of more than 17.6 meters high with diameter of 42.8 meters at the base. The works were performed by RosSEM Trust , part of Rosatom Engineering Division, said a press release.
"Concreting of inner containment dome is the final stage of construction of the passive safety system. Next stage works include CPS strands tensioning and the containment testing", said Alexey Deriy, the vice president of ASE and director of Rooppur Nuclear Power Plant construction project.
The inner containment is one of the main elements of the NPP safety system. It not only protects the reactor compartment but also provides support to the pipelines penetrations and the polar crane, which is used for servicing the reactor, the press release added.
Rooppur NPP with two generation 3+ VVER-1200 reactors is being constructed under the Russian design.
General designer and the general contractor of the project is the Rosatom State Corporation Engineering Division. The plant will have total capacity of 2400 MW.
