ОN THE ISSUE OF WATER SUPPLY FOR THE RIVNE NUCLEAR POWER PLANT

Abstract

The article is devoted to the analysis of water supply and water use systems of the Rivne Nuclear Power Plant (RNPP) and the assessment of their impact on surface and groundwater resources. The study examines the sources of technical and drinking water supply, including surface water abstraction from the Styr River and groundwater intake from artesian wells. Particular attention is paid to the volumes of water withdrawal, water consumption structure, and the characteristics of return water discharges into the receiving water body. The paper presents the results of long-term monitoring of surface and groundwater quality within the RNPP impact zone. Quantitative and qualitative indicators of wastewater discharges are analyzed in comparison with established maximum permissible discharge standards and regulatory limits for special water use. The effectiveness of industrial, stormwater, and domestic wastewater treatment facilities is assessed based on laboratory control data. The analysis shows that the operation of the Rivne Nuclear Power Plant is carried out in compliance with valid permits, established water abstraction limits, and environmental regulations. Actual concentrations of pollutants in return waters do not exceed permissible values and do not cause deterioration of the hydrochemical state of the Styr River. Comparative assessment of water quality upstream and downstream of the discharge point confirms the absence of significant anthropogenic impact on the aquatic ecosystem. The implemented environmental protection measures, including the use of closed-loop cooling systems and continuous monitoring of water quality, contribute to minimizing the environmental impact of the nuclear power plant. The results indicate the stability of water use indicators and confirm the controlled and environmentally safe operation of RNPP with respect to regional water resources.
