Construction of spray ponds, one of the key elements of the technical water supply system, has begun at the construction site of the third power unit of Leningrad NPP-2. Specialists building the power unit with a VVER-1200 reactor have started implementing this new stage of the project.
Spray ponds are designed to remove excess heat from the equipment that ensures the operation of the power unit. They will cool pumps, heat exchangers, aggregates, and other important elements of auxiliary systems. The project involves the construction of two artificial reservoirs, each 124 meters long, 74 meters wide, and 4.5 meters deep.
Currently, the excavation of the pit and the installation of the blanket drainage are being completed at the site. The next stage will be the reinforcement of the foundation slab of the first pond, which is planned to begin in August.
As reported at the station, the design of the structures is significantly more complex than it may appear externally. Each pond will be divided into open and closed parts. This engineering solution will allow the system to remain operational even during extreme natural phenomena, including tornadoes and hurricanes, as well as potential man-made impacts associated with a shock wave.
