On the thermal conductivity and diffusivity of solid and liquid uranium dioxide
This paper describes the methods employed by various experimental programmes that were set up to determine the thermal conductivity, k, of liquid UO(2). The final results of the programmes were in such disagreement that it remained an insoluble difficulty. This paper also describes recent experimental determination of the heat capacity of this material, at temperatures from 2500 K to above the melting point. This makes it possible to evaluate the heat diffusivity, alpha, in this temperature range. A discussion of the dependence of alpha on temperature indicates that the lowest measured value of k is the right one.
