      abstract     = {It is clear that closed nuclear fuel cycles with the
                      recycling of spent nuclear fuels can enhance the
                      sustainabilityof nuclear energy (Taylor et al. 2022a,
                      2022b). In Europe two strands of research have been
                      followed: (a) theheterogeneous recycling of (U,Pu) in the
                      PUREX process followed by a minor actinide separation
                      process(Geist et al., 2021) and (b) the homogeneous
                      recycling of actinides in a grouped actinide extraction
                      (GANEX)process. The GANEX option has some advantages since
                      it is based on fully decomposable (“CHON”) solventsand
                      produces separate uranium and transuranic products – this
                      adds a proliferation barrier due to theplutonium being mixed
                      with minor actinides.The first GANEX cycle (GANEX-1) to
                      separate the bulk uranium uses a monoamide as a selective
                      extractant.The second cycle is more complex and a number of
                      concepts have been developed in Europe over the last15+
                      years, including within European collaborative projects
                      (ACSEPT, SACSESS, GENIORS). The GANEX-2cycle requires
                      innovative solvent formulations capable of co-extracting
                      plutonium and the minor actinides(including neptunium) as
                      well as separating the trivalent minor actinides from the
                      lanthanides. Processes havebeen developed and tested on the
                      lab scale, including hot tests with spent fuel (Lyseid
                      Authen et al., 2022).The various solvent extraction
                      processes are briefly introduced, the most suitable choices
                      are pointed out, andthe process schemes are compared to one
