Abstract: This document provides the results of an experimental demonstration and validation of a spiked AMSEL flowsheet test, which was conducted at FZJ. The AmSEL process uses TODGA as an extractant and SO3-Ph-BTBP as an Am(III) selective complexant. The process was run in the 16-stage centrifugal contactor setup installed in the FZJ laboratories, using a flowsheet designed and optimised by CEA. An Am(III) product containing 45% Am(III) with only 5% Cm(III) contamination was obtained. The remaining Am(III), Cm(III) and Ln(III) were routed to the spent solvent. The separation from Ln(III) was very good with high decontamination factors. However, significant recycling of Am(III) occurred, which needs to be addressed in further process optimizations. More centrifugal contactor stages are required to improve Am(III) recovery and the Am/Cm decontamination factor.
