The diffusion coefflcients of hydrogen in BETA -zirconium were calculated from experimental hydrogen sorption curves. The results were D (cm/ sup 2//sec) = 5.32 x 10/sup -3/ exp (--8320/RT), (760 to 1010 deg C). This relationship was independent of hydrogen concentrations (to 41 at.% H) and oxygen concentrations (to 4.2 at.% O) in BETA -zirconium. Oxygen in solid solution with zirconium and surface films on the zirconium reduced the rate of hydrogen sorption by zirconium. The effect of oxygen in solid solution with zirconium was observed to be related to the alpha to BETA transformation, while the effect of surface films was related to the hydrogen concentration at the film-zirconium interface.
