Pyrochemical processes for recovery of actinides from spent nuclear fuels

This chapter discusses different aspects of pyrometallurgical processing of spent nuclear fuels. Initially, the applicability of pyrochemical separation processes within the advanced nuclear fuel cycle and waste management strategies is mentioned. The following technical part is focused mainly on electrochemical separation processes. The basic studies needed for the process development are described, including a summary of the achieved results on electrochemical and thermodynamic properties of actinides dissolved in selected molten salt media used for the processes. The last part is devoted to the principle and main achievements of electrorefining process using solid aluminium cathodes for homogeneous recovery of actinides from metallic fuel.
