Under the guidance of the Nuclear Science Committee, the Working Party will deal with scientific issues in various existing and advanced nuclear fuel cycles, including fuel cycle scenarios, physics, separation chemistry and flowsheets, waste forms, fuels and materials, and coolants.
To provide member countries with up-to-date information on and develop consensus regarding:
Fuel cycle scenarios:
- Assessment of advanced fuel cycles scenarios, including resource utilisation, waste management and transition phases.
- Fuel cycle tools and databases and evaluation of associated uncertainties.
- Keep updated information on separation technologies, including advanced aqueous and pyrochemical processing issues for different fuel cycle scenarios.
- Evaluation of advanced processing concepts, including design bases for future reprocessing plants, and review of current robotics used for spent fuel reprocessing.
- Improvement of waste management in advanced fuel cycles: reduction, recycle and reuse.
- Keep updated information on fuels development for implementing in advanced systems and associated fuel cycles.
- Evaluation of innovative fuels, including fabrication processes, characterisation, behaviour, property measurement, performance and qualification.
- Identification of advanced materials to meet systems requirements for advanced systems.
- Assess current status and future needs for qualification of reference structural materials.
- Identification and elaboration of areas where experimental protocols and standards are needed.
- Identify existing databases.
Liquid metal and coolant technologies:
- Assessment of the environmental effects relevant for construction standards based on a fundamental understanding of materials behaviour
- Answer key technical issues to address radiological impact, operation, handling, maintenance and inspection as relevant for licensing.
Technology and components of accelerator-driven systems (workshop):
- Accelerator and neutron source.
- Subcritical system design and relationship to nuclear fuel cycles.
Liaise closely with other relevant NSC working parties and NEA standing technical committees, especially the Nuclear Development Committee (NDC) and the Radioactive Waste Management Committee (RWMC), to ensure the respective work programmes are complementary and to provide advice and support where required, undertaking joint work where appropriate. Particularly close working relationships will be maintained with the Working Party on Scientific Issues of Reactor Systems (WPRS) and the Working Party on Multi-scale Modelling of Fuels and Structural Materials for Nuclear Systems (WPMM), as well as with the Generation IV International Forum (GIF).
The Working Party will also work in co-operation with other international organisations (EU, IAEA).
