Abstract Viscosities of uranium solutions in H2O and 3 mol/L HNO3 medium were measured by Ubbelhode flow viscometer in the concentration range of 0.5%-3.0% from 10 °C to 30 °C at 5 °C interval. Viscosity data were interpreted in terms of an empirical equation; h=aoexp(boM+coM2). Values of coefficients ao, bo and co were calculated for all the three systems studied. Flow activation energies and thermodynamic parameters were also evaluated.
