Separation of americium and curium for transmutation in the fast neutron reactor

•TODGA – F-3 extraction system was tested with real PUREX-process raffinate.•Recovery of 99,9% of americium and curium were demonstrated.•Chromatographic separation of americium and curium was tested with concentrate of MA and heavy REE.•Fractions of Am a purity of more than 99.9% was obtained. As part of PRORYV project activities dynamic tests of extraction systems (CMPO – TBP - F-3, Dyp-7 - F-3, ATP – CCD – F-3 (UNEX-T) и TODGA – F-3) were carried out. With the use of TODGA – F-3 from raffinate of PUREX-process from recycling of SNF WWER-440, the deep extraction of americium and curium was demonstrated (99,9% from the initial content). Using the concentrate of MA and heavy REE from recycling of SNF WWER-1000 experiments on chromatographic separation of americium and curium were carried out. The fractions of Am a purity of more than 99.9% was obtained. Mathematical models have been developed for all the processes studied, both for the process itself and for the operation. Verification of mathematical models on model and real products is planned.
