Abstract

The energy strategy of Ukraine until 2030 envisages the completion and commissioning of power units 3 and 4 at the Khmelnytskyi NPP. An important factor in the correct, uninterrupted operation of the Khao NPP is the availability of appropriate water resources and water levels that can be restored with the help of precipitation, as well as flow regulation. During the research period from 2019 to 2023, the cooling pond of Khao NPP was not recharged by pumping water from the Horyn River. The research methodology is based on the application of the hydrological-genetic and statistical method. The homogeneity of the series of observations according to statistical parametric and non-parametric criteria was determined; integrated total curves of water levels were constructed; graphs of surfaces are constructed; the precipitation unevenness coefficient was calculated. The possibility and expediency of applying statistical criteria to assess the significance of the presence of trends, which were revealed based on the data of observations of water levels and precipitation for the Horyn River near the village, is substantiated. Yampil and in the Khao NPP cooling pond. It was established that in most cases, the heterogeneity of the observation series can be influenced by anthropogenic factors, such as the regulation of the reservoir, the operation of reclamation systems, agricultural fields, overgrowth of the banks of the pond, siltation and waterlogging, floodplain meadows, and others. In cases of insignificant annual distribution of precipitation in the Yampil River and in the Khao NPP cooling pond, the latter does not have a significant impact on the distribution of water levels in them.
