Installation of the dome part of the outer containment of Unit 2 reactor building has started at the construction site of Rooppur NPP in the People’s Republic of Bangladesh (General Designer and General Contractor is Rosatom Engineering Division).
Installation of the lower tier of the outer containment dome has been completed. The installation of the oversize structure weighing 200 tons with the diameter of 46.3 meters lasted about 5 hours. The outer containment was raised and installed in the design position at the elevation of 48.8 meters.
“The outer containment is one of the key localizing safety systems. It is a reinforced concrete structure protecting the reactor plant from external impacts, which is able to withstand an earthquake, tsunami or hurricane”, commented Alexey Deriy, ASE JSC Vice President - Director for Rooppur NPP construction project.
The Rosatom Engineering Division unites the leading companies of the nuclear industry, namely: Atomstroyexport JSC (Moscow, Nizhny Novgorod, branches in Russia and abroad), Joint Design Institute - Atomenergoproekt JSC (Moscow, Nizhny Novgorod, St. Petersburg branches - design institutes, branches in Russia and abroad, R&D branches) and subsidiary construction organizations. The Engineering Division ranks first in the world by the order portfolio and the number of NPPs constructed simultaneously across the world. About 80% of the Division’s revenues originate from foreign projects. The Engineering Division implements construction projects for high-power NPPs in Russia and across the world, renders a full range of EPC, EP, EPC(M) services including project management and design activities, and develops Multi-D technologies for the management of complex engineering facilities. The Division relies on the achievements of the Russian nuclear industry and innovative state-of-the-art technologies.www.ase-ec.ru<http://www.ase-ec.ru/>
Apart from the outer containment, the reactor building is protected with the inner containment that was installed in June 2022 and was concreted in May 2023. A double containment is a distinctive feature of the Russian design of power units with VVER-1200 reactors, ensuring the highest level of safety.
