Summary:

The density and thermal expansion of molten UO/sub 2/ were measured from 3120 to 3250/sup 0/K using the gamma attenuation technique. The density-temperature relation for molten UO/sub 2/ was found to be rho(T) = (8.86 +- 0.06) - (9.16 +- 0.43) x 10/sup -4/ x (T - 3120/sup 0/K) for rho in g/cm/sup 3/ and T in /sup 0/K. The results agreed within experimental error with the single previous measurement. However, the value of the first derivative of density in the molten phase with respect to temperature was found to be approximately 50% higher than the value recommended in a review of properties for reactor safety analysis. 4 figures.
