Abstract
Опыт применения ингибитора солеотложений «НАЛКО 1392» в циркуляционной системе водоснабжения Нововоронежской атомной электростанции
Highlights
The water chemistry should ensure the operation of equipment without any damage to its components or the loss of efficiency caused by the corrosion of the internal surfaces as well as without scale and sludge formation
In the process of operating the circulating water supply system at the Novovoronezh nuclear power plant (NVNPP), heating leads to the cooling water oversaturation with salts, primarily, with calcium carbonate, this causing the formation of scale on the heat-exchange surfaces (Vlasova 2007, Vitkovskiy et al 2017)
An alternative way to cope with the negative effects of the high carbonate hardness of water is to maintain such water chemistry in the system with which the scale crystals formed are stabilized within the water column by the action of the salt scaling inhibitor and do not settle on the heat-transfer surface (Ivanova and Cherkasova 2016, Procedural recommendations)
