An existing mathematical model that describes the contamination of isothermal steel surfaces in water-cooled nuclear reactors by radioactive corrosion products in high-temperature water is extended by including a term for mass transfer across the fluid boundary layer. Fits to experimental data from recirculating and once-through loops remain good, while predictions of corrosion rate are altered slightly. Resulting variations of initial deposition coefficient and surface activity with velocity are shown.
