Rooppur 1 Dome Set In Place

Installation of metal structures for the inner containment dome has been completed in the power unit No. 1 reactor building at the Rooppur NPP construction site in the People's Republic of Bangladesh (PRB) said the project general contractor ASE, the engineering division of Russian nuclear power player Rosatom.

Rooppur 1 Dome placementSpecialists of the Trest RosSEM LLC subcontractor in the PRB implemented the lifting and installation of the last tier of the inner containment dome. With a weight of 230 tons, the dome was lifted by a Liebherr heavy crawler crane with a 1350 ton lifting capacity. The component mounted in the design position, moving from +51.700 elevation to +60.500 elevation, completes installation of the inner containment metal structures of the reactor building.

The next stage of works at this power unit will include connecting and starting up a polar crane, assembling a reactor vessel, a steam generator, and a primary circulation pipeline.

The installation works on the inner containment dome mounting were carried out in two stages - from +44.100m elevation to +51.700m elevation and further on to an elevation of 60.500m. The lower part of the dome is a metal structure of 44m diameter and 185t weight. The lower part was installed a week earlier.

In the near future, specialists will start concreting the inner containment above the +44.100 elevation.

The construction schedule calls for the installation of the power unit No. 1 reactor vessel into the design position sometime in September.

The Rooppur NPP site is located on the eastern bank of the Ganges River in the Pabna district at a distance of about 160 km northwest of the city of Dhaka, the capital of the Republic of Bangladesh. The facility is designed and constructed by the Engineering Division of the ROSATOM State Corporation. The nuclear power plant will consist of two VVER-1200 reactor power units, their life cycle is expected to be 60 years with the possible extending of the service life for another 20 years. The Russian design with VVER-1200 reactors successfully implemented at Novovoronezh NPP- 2 was selected for the first NPP in Bangladesh. This is an evolutionary GenIII+ design that fully complies with all international safety requirements.
