Kurk II Cooling Tower To Be Russia's Tallest
The Kursk NPP-2 evaporative cooling tower will become the tallest one in Russia, with its expected height being 179 meters -- a bit taller than 587 feet, the plant said on Monday.
The construction team has started concreting the tower’s ring footing. Over 1,100 cubic meters of concrete have been placed into the first section. A total of 6,050 cubic meters will have to be placed into the foundation subdivided into 5 sections.
‘The preparation activities prior to the cooling tower construction began in late 2019. We have set up a sand-gravel foundation, finalized the concrete blinding, and just recently, we have completed the ring footing reinforcement of 280 tons’, Rostislav Kimlik, the deputy chief engineer of the capital construction and the head of construction control team at the Kursk NPP-2, said. ‘Since the cooling tower will be the tallest one, the outer surface of the cooling tower cover is breaking the record, too, with 53,150 square meters’.
The Kursk NPP-2 construction project calls for the installation of evaporative cooling towers, one for each power block. The stacks work as a part of the power block’s cooling system. Water circulates in a closed circuit, thus removing unnecessary heat from the units. Cooling towers are used to lower the water temperature. The water cooling process is facilitated by thermal exchange with water. Cooling water is distributed all over the spraying system using spraying devices (nozzles). Natural draught cooling towers are environmentally friendly thanks to the energy savings they provide. Stacks have the same function as water ponds – they disseminate unnecessary heat produced during water cooling into the atmosphere. In the meantime, water returns into the cooling system cycle.
The cooling tower’s ring footing radius is 71.736 meters, the total amount of concrete used to form the cover is 14,078 cubic meters.
In 2020, the construction team plans to erect the structure of the evaporative cooling tower as high as 10.7 meters.
