Under the guidance of the Nuclear Energy Agency's Nuclear Science Committee (NSC) and the mandate of the Working Party on Scientific Issues of the Fuel Cycle (WPFC), the Expert Group on Innovative Fuels Elements (EGIFE) has been established with the objective of conducting joint and comparative studies to support the development of innovative fuels such as homogeneous and heterogeneous fuels, accelerator-driven systems (ADS) fuels, and oxide, metal, nitride and carbide fuels, all of which can be implemented in advanced nuclear fuel cycles with fast reactors. The scope of the expert group covers innovative fuel fabrication techniques, irradiation performance of innovative fuels, characterisation and post-irradiation examination methods and predictive codes for innovative fuel fabrication and performance. This report presents recommendations on oxide and metal fuel properties for fuel performance codes that have been established by the experts in this field and based on selected data.
