Development of the regulation of hydrobiological monitoring in circulation cooling system of the Zaporizhzhia nuclear power plant

The article proposes a new approach to solving the problem of biofouling at facilities circulating cooling system Zaporizhzhia Nuclear Power Plant (ZNPP) by regulating hydrobiological studies. In course studies, 4 species hydrobionts were found that formed massive fouling on water supply facilities: filamentous algae Oedogonium sp. and Ulotrix zonata with total biomass 123.6±18.44 g/m2, tropical molluscs Melanoides tuberculata Tarebia granifera Thiaridae family 20.09 g/m2. shells dead mollusks drifted along pipes circulation flow interfered operation pumping stations. Also, blue-green Microcystis aeruginosa, which dominated phytoplankton pond, belonged potential bio-hindrances. regulation was developed aim timely detection capable active reproduction creation biological obstacles. It provides for four types monitoring: current (operational), extreme (control), deployed (research) background (hydrobiological monitoring Kakhovka reservoir in zone influence waste warm waters). For each type monitoring, subjects control (a group hydrobionts), parameters (species composition, abundance, biomass) frequency are determined. makes it possible minimize consequences or prevent occurrence accidents emergencies ZNPP systems associated obstacles, can be used as an example similar problems other power facilities. also contains practical recommendations improving ecological state pond preventing development dangerous aquatic organisms introducing biomeliorator fish different food spectrum into
