Abstract
:
The effective diffusion coefficient of oxygen into Zircaloy-4 oxide layer at temperature range from .1173 to 1773 K were determined by applying a recent experimental kinetic data to an analytical expression. The reaction of the Zircaloy-4 in steam at elevated temperatures involves the growth of discrete layers of oxide depending on the reaction medium temperature, which lead to the development of a diffusioncoefficient equation to characterize the diffusion at each temperature interval. The results of the proposed diffusion coefficient equation in this study have been compared -with experimental data and show a good agreement.
