A Study of the Chemical Diffusion of Oxygen in (U sub 0.8 Pu sub 0.2 )O sub 2--x at 1400 deg C

A Study of the Chemical Diffusion of Oxygen in (U sub 0.8 Pu sub 0.2 )O sub 2--x at 1400 deg C

The coefficient of chemical diffusion of oxygen in (U sub 0.8 Pu sub 0.2 )O sub 2--x at 1400 deg C was determined for nonstoichiometric conditions between x = 0-0.036 to be D = (3.4q0.5) x 10 exp --9 m exp 2 s exp --1 . There was good agreement for results obtained between 600-1400 deg C, indicating...

Zusammenfassung:The coefficient of chemical diffusion of oxygen in (U sub 0.8 Pu sub 0.2 )O sub 2--x at 1400 deg C was determined for nonstoichiometric conditions between x = 0-0.036 to be D = (3.4q0.5) x 10 exp --9 m exp 2 s exp --1 . There was good agreement for results obtained between 600-1400 deg C, indicating that the activation energy over this whole range is identical. Graphs. 7 ref.--F.H.H.
