Dhaka, March 3, 2021 (PR) - Subcontractor specialists - Trust RosSEM, Roin World LLC and Energospecmontazh JSC performed complex works on installing two polar crane beams on rail tracks at the first power unit of the Rooppur NPP.
These are the main metal structures of the crane, with the help of which the operations for the transportation and installation of the main technological equipment of the containment area (reactor vessel, steam generators, pressure compensator) will subsequently be carried out.
The beams of the polar crane were installed in the reactor building using a Liebherr heavy crawler crane, at an elevation of +38.500 m.
“Installation of heavy structures required complex and well-coordinated work of subcontractors. The specialists of Roin World LLC provided the preparation of the access road for lifting the beams by the crane, the specialists of Trust RosSEM completed the installation of containment lobes for the installation of the rail track at 38,500 m in the shortest possible time, the specialists of Energospecmontazh JSC carried out the final operation - the installation of the beams on the rail ways ", - said the deputy director for project management of the branch of ASE JSC in the People's Republic of Bangladesh - chief project engineer Yuri Koshelev.
Currently, work is underway to install structures and crane mechanisms on crane runways.
Due to the movement of the crane along a circular path, it will be able to perform all loading and unloading operations at any point in the reactor compartment.
It is planned to complete the installation of the polar crane (circular crane) in June this year, then the installation of large and heavy equipment of the reactor plant of the first unit of the NPP will begin.
After the NPP is put into operation, the crane will be used for repair work and fuel transportation.
The Rooppur NPP with two VVER-1200 reactors with a total capacity of 2,400 MW is being built according to a Russian project 160 km from the capital of Bangladesh, Dhaka, in accordance with the general contract dated December 25, 2015. The general contractor for the construction of the Rooppur NPP is Atomstroyexport (Engineering Division of Rosatom).
For the first nuclear power plant in Bangladesh, a Russian project with VVER-1200 reactors was selected, which was successfully implemented at two power units of the Novovoronezh NPP. This is a generation III + project that fully meets international safety requirements.
