Technogenic pollution of environmental objects determines the relevance of work on the analysis of ensuring environmental safety requirements during the operation of nuclear power plants when copper ions enter water bodies with discharges from nuclear power plants. The paper analyzes the dynamics of both actual discharges of copper ions for Balakovo NPP, Novovoronezh NPP and Smolensk NPP (t / y), and in fractions of the normative permissible discharges for this heavy metal (%). The absence of violations of environmental safety requirements is shown. A more detailed analysis was carried out for the Rostov NPP. It is shown that the modernization of the turbine condenser pipe systems of the power unit No. 1 led to a sharp decrease in the flow of copper ions into the cooling pond from the nuclear power plant. Analysis of the toxicant content dynamics in the water of the cooling reservoir and the Tsimlyansk reservoir did not reveal the effect of the influx of copper ions from the cooling reservoir with filtering water on their concentration in the reservoir water.
