The results of an analysis of the thermal impact of the circulating cooling water discharged after cooling equipment in the Kalinin NPP on the thermic regime of the cooling reservoir and the climate in the littoral areas are presented. The impact was evaluated by comparing the hydrometeorological characteristics before the commissioning of the nuclear plant (1971–1983) and during its operation at full power (2013–2016) with similar characteristics in the background areas. It is shown that the impact of the Kalinin NPP on the littoral climate is very small and manifests only in a strip 200–300 m from the water edge. The main impact of the plant was to increase the water temperature in the cooling water reservoir and to increase evaporation from the surface of the reservoir.
