“…When discussing about nuclear waste, the P&T community delivers the reduction of radiotoxicity over time normalized to one ton see e. g. [35,36] with the caveat that radiotoxicity is a weighted unit overemphasizes the effect of heavy isotopes due to a higher toxicity index. An approach often criticized in the final disposal community [37].…”

Traditionally there is a gap between reactor operation and the consideration of nuclear waste in the final disposal. Fuel is produced and fuel must be disposed of in the view of the reactor operator, fuel has to be cleaned in the reprocessing and new solid fuel has to be produced in the view of the chemist. iMAGINE is designed to overcome this separation through the breakthrough development applying an optimized, integrative approach from cradle to grave of nuclear energy production as a first step to come as close as possible to the vision of zero waste nuclear power. It is described here the first time all in three the steps: reactor, fuel cycle, waste, providing the ratio behind each of the choices taken to come to the overall solution to open the discussion and thinking process on what could be achieved by a really innovative approach to integrated nuclear energy production. The opportunities regarding the handling of the remaining waste will be discussed with a view on the expectation of the final disposal community, the study ‘Nuclear waste from small modular reactors’, and the IAEA report ‘waste from innovative types of reactors and fuel cycles - a preliminary study. The aim of the is not to find answers to each of the raised points, but to identify first potential approaches and potentially promising ways to go, as well as to stimulate a discussion among experts. In the best case this could lead to a change of track for nuclear to become an even more sustainable and at least as important, trusted technology to help solve the net-zero challenge.

“…Safety of advanced nuclear systems and fuel cycles [11][12][13][14][15][16][17] is supported through R&D towards a new generation of more sustainable reactor technologies. Safety design and licensing of technologies are also identified as a high priority by the European Sustainable Nuclear Industrial Initiative of the Strategic Energy Technology Plan SET-Plan (SNETP-ESNII Generation IV fast reactors and closing the fuel cycle).…”

The development and safe operation of nuclear installations in Europe is of vital importance for the future of nuclear energy. Helping to ensure the safe operation of nuclear power has always been one of the top priorities of Euratom Research Framework Programmes. With the incentives of Horizon 2020, further integration towards an EU/Euratom Research Area was achieved, better prioritisation at European and International levels based on updates of Research and Innovation agendas or deployment strategies, capitalisation of European Technology platforms and enhanced cooperation with International Organisations or Fora effectively happened. Evolutions towards European Joint Programmes together with EU/Euratom Member States, confirm that research and innovation programmes successfully benefit from a truly added value of a concerted European approach in nuclear safety research and training advocated by the European Commission and EU/Euratom Member States.

“…The partitioning and transmutation (P&T) strategy has been proposed as an effective way to curb the nuclear waste problem, as it can reduce the volume and mandatory storage time for spent fuel significantly. − Lanthanides (Ln), due to their large proportion relative to the actinides (An) and high neutron-absorption cross sections that would adversely affect the transmutation, are required to be removed from An before the transmutation process . However, the similarity between the trivalent actinides (An(III)) and lanthanides (Ln(III)) in chemical properties makes the separation of An(III) and Ln(III) a very challenging task .…”

The extraction and complexation of trivalent americium (Am) and lanthanides (Ln) by four 2,9-diamide-1,10-phenanthroline (DAPhen) ligands with different alkyl substituent groups on the diamide moiety in an ionic liquid (IL), C 4 mimNTf 2 , were studied through a combination of batch extraction, spectroscopic, and calorimetric approaches. All four DAPhen ligands can achieve selective separation of Am(III) from Eu(III), but the detailed extractability and the extraction kinetics are affected significantly by the length of the alkyl substituent groups. UV−vis absorption spectrophotometric titrations indicate that Ln(III) coordinates with all four ligands in a 1:2 mode in the ionic liquid and the binding strength decreases with the increase of the alkyl chain length. The complexation of the DAPhen ligands with Ln(III) in the ionic liquid is driven by highly positive entropies and opposed by endothermic enthalpies. A luminescence spectroscopy study suggests that each DAPhen ligand coordinates in a tetradentate form with Eu(III). This work further unravels the unique extraction and coordination behavior in an ionic liquid system and offers additional guidelines to design more efficient DAPhen ligands for Ln(III)/An(III) separation.
