N2 - The effect of flow velocity, pH and lithium concentration on corrosion product deposition in accelerated flow regions was investigated in simulated nuclear reactor primary water using discs containing micro-orifices. The results also showed that a well adhered crystalline deposit formed between 2 and 2.5 ppm lithium, where the zeta potential of stainless-steel specimens is negative and the electrokinetic effects are expected to dominate. Conversely, a loosely adherent deposit driven by the deposition of particulates was formed for lower lithium concentrations.
