Abstract — The research data concerning the biological corrosion of construction materials for nuclear power plants (NPPs) are submitted in this article. The corrosion kinetic features of 08Kh18N10T and 20 steels in industrial neutral electrolyte are analyzed before and after the above steel types are contaminated with microorganisms. The effects of microorganisms and the products of their metabolism on the corrosion of biocide component-protected steels are evaluated.
