Description
The causes of corrosion damage of steam generator tubes of a WWER-440 reactor were investigated by metallographic tomography and by a method based on measurements with the DENKMAN system. Electron microanalysis was also applied to examine the composition of corrosion products in cracks. Corrosion damage of stainless steel tubes is a result of combined action of factors associated with the tube material, the flowing-through medium, and the load determined by the thermohydraulic conditions and design features. Local corrosion appears in sites where all the three factors exert an adverse effect. Precise knowledge of the tube damage kinetics is a prerequisite for a scientifically grounded forecast of the steam generator lifetime. (Z.M.). 21 figs., 4 refs
