The diffusion rates of oxygen in alpha and beta Zircaloy-2 and Zircaloy- 3 were determined in the range 1000 to 1500 C. For alpha Zircaloy-2, the variation of the diffusion coefficient, D, in cm/sup 2//sec, with tempera:. ture is given by the equation D alpha = 0.196 exp (-41,000 the J-57 engin 1500/RT). For beta Zircaloy-2, D/sub beta / = 0.0453 exp oxygen in alpha and beta Zircaloy- 3 to 1100 and 1400 EC show that the rates are in close agreement with those for oxygen in Zircaloy-2. The diffusion coefficients for oxygen in beta Zircaloy- 2 and Zircaloy-3 are about 10 times greater than those for nitrogen in high- purity beta zirconiunn. (auth)
