Abstract

The evaporation dynamics of Fe element in uranium melting during vacuum induction melting have been studied. The results of experiment and calculation show that the evaporation rate of Fe is the first order with respect to Fe content in the metal. The activation energy of evaporation of Fe from uranium melt is 121 kJ/mol, and the rate of Fe evaporation is simultaneously controlled by the diffusion through the liquid boundary layer and the evaporation reaction of Fe at the metal/gas interface, in which the mass transfer coefficient is estimated to be from 4.52x10(-4) cm/s at 1673 K to 1.01x10(-3) cm/s at 1853 K.
