Results of the study of phytoplankton of the cooling pond of the Khmelnitskiy Nuclear Power Station are given in the paper. It has been shown that the distribution of phytoplankton in the cooling is non-uniform, which is conditioned by water circulation and by the influence of wind. Characteristics of the ecological state of the cooling pond are given based on the bioindication indices of plankton algae, including the type of their habitat, their relation to thermal, hydrodynamic, and oxygen regime, pH, organic matter and nutrients content, and also the type of their nutrition. Results of the ecological characteristics of the cooling pond based on the bioindication indices of phytoplankton were compared to those obtained using the procedure of the ecological assessment of the quality of surface waters.
