Abstract: 
Experimental results for thermal diffusion of oxygen in both hypo-and hyperstoichiometric uranium based oxides are reviewed, and the influence of a metallic encapsulation on thermal diffusion in nuclear fuel pellets is analysed. The collected data for the heat of transport Q(0)* of the mobile oxygen component show a minimum in the vicinity of the stoichiometric composition which is interpreted on the basis of a straightforward analysis of thermal diffusion in mixed conductors with a variable composition. It is further shown that the experimental data for the heat of transport Q(0)* in (U,Me)O2+delta can be used to extract information on the defect structure.
