The inner radius of the IC unit is 22 meters, the height is 8 meters and the weight is more than 144 tons.
The assembly of the tier was carried out for three months near the Unit No.2 construction site.
The installation of the steel structures was carried out by two crawler cranes Liebherr LR-13000, truck crane Liebherr LTM 1300 and two hydraulic devices. A special lifting beam was designed to protect the structure from deformations in the course of handling by crane.
