1999/11/1 · Steam generator (SG) corrosion is a major problem in the operation of Pressurized Water Nuclear Reactors (PWRs). Among other factors, corrosion is due to the segregation and concentration of impurities in the tube/support plate and tube/tube sheet crevices.

Corrosion in pipes can advance into the interior parts of the metal over time, which may lead to pipe thinning and eventually pipe failure if left untreated. Furthermore, corrosion by-products are often carried downstream in piping, which can contaminate the fluid, cause the erosion and further corrosion of piping, and clog valve orifices.
