FIELD: chemistry.
SUBSTANCE: invention relates to power engineering and can be applied in NPP, in the secondary loop with pressurised water reactor. Claimed is method of suppressing corrosion in the secondary loop of installation with pressurized water reactor and system, provided with steam-generator, turbine, condenser and heater, in which non-deaerated water is recycled water, which was not processed by either deaerator or introduction of chemical substance by device for chemical substance introduction. Substance, representing oxide, hydroxide, carbonate, compound of acetic acid or oxalic acid of metal elements, selected from Ti, Y, La, Zr, Fe, Ni, Pd, U, W, Cr, Zn, Co, Mn, Cu, Ag, Al, Mg and Pb, is applied on construction element, which comes in contact with non-deaerated water.
EFFECT: invention will make it possible to suppress corrosion and reduce expenditures on equipment and operating costs.
