Apostolidis, R. Carlos, O. Courson, J.-P. Glatz, R. Malmbeck, G. Pagliosa, K. Römer, D. Serrano-Purroy] In the present work the performance of several processes used for advanced reprocessing of commercial LWR fuels as well as transmutation targets is compared. As a first step uranium and plutonium were recovered by PUREX type reprocessing. The raffinate, containing fission products including lanthanides and the minor actinides (MA) was used as feed for the second step in which minor actinides and lanthanides were separated from the bulk of the fission products. The five different processes tested use CMPO, DIDPA, TRPO, Diamide and CYANEX 923 as extractants. In the third step MA are separated from lanthanides. Here three processes were tested, i.e. using CYANEX 301, the synergistic mixture of di-chloro substituted CYANEX 301 and TOPO, and BTP solvents. Column-, batch- and continuous counter-current extraction techniques were used for the tests. The different processes will be described and discussed in terms of performances and efficiencies for Am and Cm separation. Efficient separation of MA from different genuine fuel solutions could be demonstrated and thereby also the possibility of closing a future transmutation fuel cycle. The combination of Diamide and BTP seems to be the best, among extractants tested, to achieve an efficient MA recovery from spent fuel. © 2004 Oldenbourg Wissenschaftsverlag GmbH Laboratory techniques, experiments nationallicence Analytical chemistry nationallicence Inorganic chemistry nationallicence Christiansen Birgit aut Apostolidis C. aut Carlos R. aut Courson O. aut Glatz J.-P aut Malmbeck R. aut Pagliosa G. aut Römer K. aut Serrano-Purroy D. aut Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 92/8/2004(2004-08-01), 475-480 0033-8230 92:8/2004<475 2004 92 ract https://doi.org/10.1524/ract.92.8.475.39283 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/ract.92.8.475.39283 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Christiansen Birgit aut NATIONALLICENCE 700 1- Apostolidis C. aut NATIONALLICENCE 700 1- Carlos R. aut NATIONALLICENCE 700 1- Courson O. aut NATIONALLICENCE 700 1- Glatz J.-P aut NATIONALLICENCE 700 1- Malmbeck R. aut NATIONALLICENCE 700 1- Pagliosa G. aut NATIONALLICENCE 700 1- Römer K. aut NATIONALLICENCE 700 1- Serrano-Purroy D. aut NATIONALLICENCE 773 0- Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 92/8/2004(2004-08-01), 475-480 0033-8230 92:8/2004<475 2004 92 ract CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
