520 | _ | _ | |a The LUCA process was developed at Forschungszentrum Julich for the selective separation of Am(III) from an acidic solution containing the trivalent actinides Am(III). Cm(III), and Cf(III) as well as lanthanides. A mixture of 0.4 mol/L bis(chlorophenyl)dithiophosphinic acid and 0.15 mol/L tris(2-ethylhexyl)phosphate dissolved in 20% isooctane/80% tert-butyl benzene was used as the extractant. The process was carried out in centrifugal contactors using an optimized flowsheet involving 7 stages for extraction, 9 stages for scrubbing and 8 stages for back-extraction. Very encouraging results were obtained. A high feed decontamination factor was obtained for Am(III) (> 1000), and recovery in the product after stripping was higher than 99.8%. The Am(III) product was contaminated with 0.47% Cm(III). More than 99.9% Cf(III), Eu(III) and > 99.5% Cm(III) inventories were directed to the raffinate and the contamination with Am(III) (< 0.08%) was low. The experimental results were in good agreement with the predictions of a computer code. |
