Corrosion product deposits in the secondary side of nuclear plant steam generators may result in tube support plate blockage, and tube fouling. In order to improve our understanding of those two phenomena, a solid deposit growth model has been developed by the R&D Division of EDF. The validity of this model is tested by comparing the results of simulations to the actual levels of tube support plate blockage observed in some nuclear plants. The limits of the model and the strategy to improve it are discussed.
