Abstract

This study provides an assessment of the possible impact of climate change on increas-ing the temperature of water in the sources from which water is taken for open technical cooling systems. In recent years, there has been a decrease in the efficiency of nuclear reactors at Ukraine's nuclear power plants in the hot summer months of the year. Using the example of cooling ponds of operating nuclear power plants, an assessment of the mutual influence of air temperature indicators and the temperature of surface water for cooling was made. Based on the monitoring temperature data of the cooling reservoirs of the NPP of Ukraine in different months of 2020, as one of the hottest years of observations, the equations of the correlation dependences between the temperature indicators of the surface air and the temperature of the cooling water were obtained. In the OriginPro8 software environment, which is widely used as an industrial standard for data collection and visualization, a climatic forecast of the atmospheric air in the territory of Ukraine was made and a forecast dependence of the water rise in water bodies was established for the period until 2160. The obtained forecast values of the relative total efficiency of the NPP reactors of Ukraine for different periods until 2050, which indicates a gradual decrease in the output power in the nuclear power industry of Ukraine. This approach to the analysis of the operation of cooling ponds can be acceptable for evaluating the operation of thermal plants and other industrial facilities that have an open cooling pond and can serve as support for making management decisions in the context of global climate change and for preventing the risks of emergency situations on the object.
