**Abstract Scope** |
Many models have been proposed to explain the basic growth rate characteristics of zirconium alloy corrosion films, all of which treat the growing oxide layer as a single, one-dimensional moving boundary problem. The intention of this study is to investigate the hypothesis that the observed corrosion kinetics for zirconium alloys can be more accurately described by the superposition of an ensemble of oxide barrier layer elements following a stochastic growth model. The resulting model reproduces the qualitative features of typical autoclave corrosion weight gain curves. Numerical fits to experimental data suggests an improvement over previous models. |
