Measurement of the Kinematic Viscosity of 0.75LiF– 0.2BeF2–0.05ThF4 Molten Salt

  • Published:
Atomic Energy Aims and scope

Experimental data were obtained on the kinematic viscosity of 0.75LiF–0.2BeF2–0.05ThF4 melt in the temperature range 920–1155 K in order to substantiate the concept of a reactor with circulating fuel based on molten salts of lithium, beryllium, and thorium metal fluorides with added fissile materials. It is shown that the obtained viscosity is described by an exponential dependence on the reciprocal of the absolute temperature. The parameters of this dependence were determined. It is shown that the viscosity of the composition under study is described by the equation for a normal liquid at temperatures above 920 K.
