The steam generator tubes at the Indian Point 2 Nuclear Station have not exhibited severe secondary side degradation in spite of the accumulation of large amounts of hard sludge. Several different factors involving materials, operating conditions, and secondary side chemistry, may have contributed to the absence of extensive corrosion. One of these factors, explored in the present study, is the accumulation of deposits and hard sludge around the tubes. The build-up of hard sludge appears to have been caused, at least in part, from the deposition of a ferrihydrite precursor. Both SEM/EDX measurements on the sludge and radiotracer studies indicate that the migration rates of corrosive species, such as sulfate, in the sludge are extremely low in the temperature range of interest. Accordingly, the presence of the hard sludge and the underlying tube deposits may contribute to retardation of corrosive attack on the tube surface.
