Abstract

MYRRHA is an Accelerator Driven System (ADS) under development at Mol, Belgium. With the development of such ADS and also with the development of some GEN IV type reactors, new problematic waste types occur, needing a different waste treatment approach during operation and/or during decommissioning. One of the problems to be solved during the operation of the ADS MYRRHA is the removal of Polonium from the lead-bismut eutectic. This paper gives an overview of an exhaustive literature study concerning the Polonium removal techniques from a lead-bismuth eutectic melt that will be used as target and reactor coolant in the MYRRHA reactor. Five extraction techniques have recently been investigated: distillation, Polonium hydride stripping, alkaline extraction, rare-earth filtration and electrodeposition. None of these techniques has yet been applied at large scale. A detailed description of each extraction process is given. It shows that there is no ideal solution to the problem.
