The paper discusses analytical models developed to predict solution chemistry in regions of PWR steam generators, such as tube to tube support plate crevices, where corrosion has led to reduced plant availability. Formation of acidic solutions during seawater, brackish water, and cooling tower condenser inleakages is predicted. This prediction is consistent with observations of denting at such plants. At freshwater cooled plants, caustic solutions are expected to be formed in crevices; however, the strength of such solutions does not appear adequate to lead to short term caustic stress corrosion cracking of Alloy 600 tubes. Plant observations and model predictions are in reasonable agreement. Preliminary efforts on crevice thermal hydraulics also have been undertaken and have led to some interesting insights into dynamic and equilibrium crevice solution chemistry. 16 refs.
