On December 24, the concreting of the fifth tier of the inner containment of Unit 2 reactor building was completed (General Designer and General Contractor - Rosatom Corporation Engineering Division).
It took the specialists of Trest RossSEM LLC 23 hours of uninterrupted work to lay 850 m3 of self-compacting concrete mix. The fifth tier completes the cylindrical part of the inner containment - one of the main components of the NPP reactor safety system, which prevents the release of radioactive substances into the environment. Later, the dome of the power unit will be installed on it.
“The concreting of the fifth tier of the inner containment from elevation +38.180 to elevation+43.400 was completed significantly ahead of schedule. This is another proof of the high professional level of the specialists of Trest RossSEM LLC in Bangladesh and a good indication of well-coordinated work of the whole team at the construction site”, said Alexey Deri, Vice President of ASE JSC, Director of Rooppur NPP Construction Project.
Currently, the construction workers have proceeded with manufacturing of elements for the containment dome part. It is planned to complete the erection of steel structures of the inner containment dome in first half of 2022.
Rooppur NPP equipped with two VVER-1200 reactors of the total 2400 MW capacity is being constructed under the Russian design160 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, that was successfully implemented at two units of Novovoronezh NPP. This is an evolutionary Generation III+ design which fully complies with all the international safety requirements.
For reference:
Rosatom State Corporation 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.
We construct reliable and safe NPPs with III+GenVVER reactors that are in line with all international requirements and recommendations.
