Uranium-free fuels for minor actinide burning in a 400 MWth accelerator-driven system are under development within the EUROTRANS European Integrated Project. The present paper gives an overview of the results for the ongoing work. Two kinds of fuels have been selected as primary candidates: they are composite materials consisting of (Puy,MA1-y)O2-x particles dispersed in a molybdenum or magnesia matrix. The performances of these MgO-CERCER and Mo-CERMET fuels have been modelled under normal operation as well as under transient and accident conditions. Three zone cores are required to obtain reasonable operational and safety parameters that satisfy the general and specific requirements of the overall design for the lead-cooled European Facility for Industrial Transmutation. In parallel to design and safety studies, in-pile and out-of-pile experiments are carried out to gain knowledge on the fuels. Irradiations investigate the helium release mechanisms (BODEX experiment in HFR), the role of microstructure and temperature on gas release and fuel swelling (HELIOS experiment in HFR) and the behaviour of the fuels in ADS representative flux conditions (FUTURIX-FTA in PHENIX).
