With AVT water chemistry the deposition rate increased with rise in surface temperature and boiling. The opposite effects occurred under alkali (9 ppm NaOH) conditions. Comparison of deposition rates with solubility data leads to the conclusion that deposition is controlled by the degree of supersaturation of soluble iron at the surface. Corrosion of the steel was independent of the type of steel (2 1/4% Cr or 9% Cr) and amount of magnetite deposited onto the surface. The applicability of data obtained on test loops to full size steam generators is discussed.
