One of the trestles connects Heating plant building with the first and second power units of the nuclear power station. At this facility the company's employees assembled metalwork – beams and pedestrian overpasses. Al in all there are some 300 tons of steel and 90 tons of pipes 25 to 1020 mm meter in diameter.
To date, the work on this project has been mostly completed.
Another trestle that is being installed by specialists of "MSU-90" links the building of Power Unit 1 turbine with a steam chamber that will provide putting the equipment into operation.

Then with the use of a truck crane the enlarged portions are mounted on the trestle having a height of approximately 9 meters. The installation is carried out with the use of an aerial work platform.
Pipes were manufactured at the production complex "MSU-90". The length of a branch of the pipeline is 25-30 meters. It weighs approximately 400 kg. To date, 30% of the work has been done.
