The 3rd layer of the reactor building inner containment has been erected at power unit №1 of Rooppur NPP

Dhaka, August 3 - Neftegaz.RU. The works on erection and concreting of the reactor building inner containment third layer sections of Rooppur NPP power unit No.1 being constructed in Bangladesh (the General Contractor - Atomstroyexport is included in the Engineering Division of ROSATOM) have been completed.

All works on the 3rd layer were performed by TrestRosSEM specialists for the period of 118 days. Totally, 2000 cubic meters of concrete mixture was placed.

Erection of the inner containment 3rd layer - is one of the construction milestones at the Rooppur NPP site in 2020. It was achieved in compliance with the schedule. During the erection and concreting of the inner containment sections, new technical solutions were applied that allowed increasing the labor productivity.



It resulted in the spread of activities for erection of the main layer of the inner containment to support a polar crane. The polar crane is intended for installation of the reactor building main equipment (reactor pressure vessels, steam generators, main circulation pumps) as well as pipelines and other metal structures. Its structure is erected under the dome of the reactor building on a special rail in the form of a circle.

The Russian design with VVER-1200 reactors that was selected for the first NPP in Bangladesh was successfully implemented at Unit 1 of Novovoronezh NPP-2. This is an evolutionary GenIII+ design, which fully complies with all international safety requirements.
