During the operation of the nuclear power plant the system shall cool the essential consumers of the nuclear island.
The entire scope of system equipment – pipelines, electric pumps etc. were installed by specialists of the JSC "MSU-90", whereas flushing and adjustment of equipment was performed by employees of the JSC "CONCERN TITAN-2" and other contractors.
At the start of the system the water intake was provided from the spray cooling ponds. All in all there are four such ponds at the Leningradskaya NPP. Between them is placed a backup water storage reservoir. During the summer period water intended for cooling will be delivered to the ponds through special nozzles, while in the cold season it will be delivered through the heating pipeline.
The principle of operation of spray cooling ponds is identical to that of evaporative cooling towers designed to cool turbine condensers. The water in the pond is cooled due to its evaporation and heat removal when contacting with atmospheric air.
