Summary

The development of nuclear energy in Ukraine is impossible without creation of advanced maneuverable and peak capacity HPPs and HAPPs. The estimation of the value of currents in the rebar reinforced concrete of the well unit of the Dniester HAPP. It is shown that the existing stray fields in the area of findings of the hydro generator-motor may not be the cause of increased heating of reinforced concrete foundation. It is found that the cause of heating of the reinforcement foundation is the circulating current. In order to develop effective solutions to reduce heat constructs requires additional theoretical and experimental studies of the distribution of the magnetic fields and currents in the structural elements under different load conditions.

Keywords: maneuverability, hydro generator-motor, fields of dispersion, heating, fittings.
