The method of determination of the oxygen diffusion coefficient in oxide on zirconium alloys and adjacent metal using weight gain and oxide thickness measurement data was applied to Zr1Nb alloy (Zr-1%Nb based on calcium-thermal zirconium). Dependence of oxygen diffusion coefficients in oxide and alpha-phase of this alloy can be described by the following equations: D-phi = 0.0518.exp(-148083/RT), D-alpha = 0.4531.exp(-188354/RT).
