Under the guidance of the Working Party on Scientific Issues of Advanced Fuel Cycles (WPFC), the Expert Group on Innovative Fuel Elements (EGIFE) conducts joint and comparative studies to support the development of innovative fuels (oxide, metal, nitride and carbide fuels, and special mechanical forms), including cladding, for advanced nuclear fuel cycles and Generation IV systems.
The following technical issues are covered by the expert group:
Both driver fuels (i.e. uranium or uranium-plutonium fuels) and for minor actinide (MA) transmutation are considered.
R&D on innovative fuels
Irradiation results and benchmark with fuel performance codes
The expert group liaises closely with other NEA bodies, in particular the Working Party on Scientific Issues and Uncertainty Analysis of Reactor Systems (WPRS) - and within it the Expert Group on Reactor Fuel Performance (EGRFP) and the Expert Group on Reactors Multi-Physics (EGMUP) - and the Working Party on Multi-scale Modelling of Fuels and Structural Materials for Nuclear Systems (WPMM), in order to ensure the respective work programmes are complementary, to provide advice and support as required and to undertake joint work as appropriate. In addition, the expert group works in co-operation with other international organisations, including the International Atomic Energy Agency (IAEA) and the European Commission (EC).

Benchmark on Fuel Performance Codes and Experiments (password-protected for authorised participants)
The expert group dealt with the activities associated with the certification of experimental data and benchmark models along with establishing the processes and procedures for using the data and benchmark models for validation of modelling and simulation tools and data. The group's work was completed in 2020 and its scope of work is currently addressed in the Working Party on Scientific Issues and Uncertainty Analysis of Reactor Systems (WPRS).
The main mission of the Working Group on Fuel Safety (WGFS) is to advance the current understanding and address cross-cutting issues related to fuel behaviour in accident conditions, including work on associated aspects of thermal-hydraulics, oxidation, chemistry, mechanical behaviour and reactor physics.
The Working Party on Multi-scale Modelling of Fuels and Structural Material for Nuclear Systems (WPMM) was established to deal with the scientific and engineering aspects of fuels and structural materials, aiming at establishing multi-scale models and simulations as validated predictive tools for the design of nuclear systems, fuel fabrication and performance.
