Bacteria Fouling in the Systems of Technical and Circulating Water Supply of Balakovo Nuclear Power Station

The article is devoted to the study of bacteria in the system of technical water supply of Balakovo nuclear power plant (BNPP). The work was carried out in 2017. The samples were taken at the following sites: backup diesel generator of the 3rd unit (rode’s-3), pumping station of feeding pond-cooler (PSFPC), coastal pump station of unit 3 (CPS-U3), coastal pumping station of power unit № 4 (CPSP-U4), turbine hall of power unit № 3 (TH-PU3), turbine hall of power unit № 4 (TH-PU4).

Bacteria Fouling in the Systems of Technical and Circulating Water Supply of the Novovoronezh Nuclear Power Station

The paper presents the results of a study of microorganisms involved in the biofouling of technical and recycled water supply systems of the Novovoronezh nuclear power plant. Sampling was carried out at the following facilities: onshore pumping station (BPS), engine room (MH), spray pool (BB), central pumping station (CNS). The number of microorganisms that make up biofilms varied from 104 to 107 microbial cells in 1 ml. The species diversity at each object is represented by 2 to 3 types of bacteria.
