Under the guidance of the Nuclear Science Committee (NSC) and the mandate of the Working Party on Scientific Issues of the Fuel Cycle (WPFC), the expert group will study needs associated with the transition from current to future advanced nuclear fuel cycles. The objectives of this expert group are:
- to assemble, organise and understand the scientific issues of advanced fuel cycles, in particular to support emerging nuclear fuel cycle technologies; and
- to provide a framework for assessing specific national needs related to implementation of advanced fuel cycles.
These issues are critical to implementing a sustainable nuclear energy infrastructure and this expert group will:
- define the key scientific issues by collecting and comparing information available from experts in member countries, organise the information in a systematic way and provide a deep level of understanding of each of them;
- assemble technical information on the existing and future technologies, including transmutation and storage technologies;
- develop and assess generic scenarios that are representative of the different strategies envisaged in the member countries; and
- evaluate the potential of systems beyond the current thermal and fast technologies.
- New fuel cycle simulator tools.
- Scenario studies using advanced light water reactors (high burn-up, high conversion ratio, inert matrix fuel, etc.) or advanced reactors (Generation IV, accelerator-driven systems, etc.).
- Investigation of the thorium (Th) fuel cycle and transition with legacy uranium (U) cycle waste elimination.
- Scenario studies for improving sustainability: multi-recycling scenarios, impact on starting reactors on used fuel and evaluation of low enriched uranium (LEU), waste reduction, etc.
- Taskforce: Benchmark on dose rate calculations for irradiated uranium oxide (UOx) and mixed oxide (MOx) spent fuel assemblies and others.
Relationships with other bodies
The expert group will liaise closely with other study groups (e.g. European Commission, International Atomic Energy Agency, etc.) and other activities being carried out under NEA auspices, for example by the Nuclear Science Committee (NSC), the Radioactive Waste Management Committee (RWMC), and the Committee for Technical and Economic Studies on Nuclear Energy Development and the Fuel Cycle (NDC), in particular providing expertise, when necessary, on issues related to the integration of nuclear power in an energy mix.
The deliverables of the EGAFCS will be the following:
- Report on study of the management of transuranic elements.
- Benchmark on dose rate calculations for irradiated UOx and MOx spent fuel assemblies.
- Report on feasibility of closing the fuel cycle using water-cooled reactors.
