抄録

Numerical simulation of the electrotransport of fuel actinides, minor actinides and rare earths in an electrorefiner for pyrochemical reprocessing of a typical spent metallic fuel has been attempted based on an improved thermochemical model developed for application to a multicomponent system in the electrorefiner. Variation of the decontamination factors (DFs) for minor actinides and rare earths and minor actinides fraction in the cathode product (fMA_c) as a function of some important parameters such as percentage transport, catholyte concentration, fuel composition (with respect to U and Pu) and batch number (batch processing) are presented and discussed.
