Rheological and thermophysical parameters of a suspension

The determination of rheological and thermophysical parameters for chemical reprocessing of nuclear fuels in water media is discussed. The parameters include the dynamic viscosity, the thermal conductivity, the specific heat, the enthalpy of suspensions in the temperature range 200-300°C and the concentration 30-125 g/dm 3. The enthalpy of a suspension of oxides of plutonium and Np, Am and Cm was determined as a sum of the enthalpies of the mass fractions of the dispersed phase and the dispersing medium. The results show that the increase in the viscosity of a suspension of plutonium, Np, Am and Cm oxides does not exceed 5.5 % of the viscosity of heavy water.
