A study was made of the quanitative relationship between heat transfer and the corrosion of zirconium alloys through an investigation of accelerated corrosion rates as a function of thermal gradients in an oxide film. This treatment was based on available isothermal corrosion data and on heat transfer dataa obtained by direct measurements on the corroded metal. An application of this analysis to the PWR reference design indicates that heat transfer corrosion does not pose a problem for the core lifetimes under consideration However, the analysis indicates that future reactors designed for higher fluxes and surface temperatures may be limited in their operation especially for the case of heavy fouling on the corroded metal.
