Single Centrifugal Contactor Test of a Proposed Group Actinide Extraction Process for Partitioning and Transmutation Purposes

Abstract

In this work a solvent comprising of tri-butyl phosphate and bis-triazinyl, bi-pyridine in cyclohexanone has been used in a single centrifugal contactor test to evaluate its GANEX process potential. It was found that the density of the aqueous phase had to be increased to facilitate phase separation in the centrifuge. The kinetics of the system was also found to be relatively slow in the equipment of choice, especially regarding the stripping. However, it was still possible to recover more than 87% of all actinides in one extraction step with minor fission product contaminations using a flowrate of 30 ml/h.

“…7,[21][22][23][24][25] Also, hydrophilic bis-triazines were synthesized as masking agents for some metal ions that could interfere with An(III) separation. 6,[27][28][29][30][31] Consequently, a few hydrophilic BTBPs have been synthesized and tested. 6,[27][28][29][30][31] Consequently, a few hydrophilic BTBPs have been synthesized and tested.…”

“…26 With regard to the hydrophobic BTBPs and BTPhens, one of them, CyMe 4 -BTBP, is the current European reference compound for An(III)/Ln(III) separation process development. 6,[27][28][29][30][31] Consequently, a few hydrophilic BTBPs have been synthesized and tested.

Development of the Chalmers Grouped Actinide Extraction Process

“…This is the opposite to the cyclohexanone based systems where the density of the organic phase is very close to that of the aqueous one, and even more so after metal extraction, making phase separation diffi cult. This was evident in a recent centrifugal contactor test of the cyclo--GANEX system [45]. The radiolytic and hydrolytic stability of the FS-13-GANEX is the best of all four examined systems and makes it an interesting diluent for the future.…”
