R&D: Gen IV, materials, modelling, fuel cycle
Updated: 5 October 2025. Objective: strengthen scientific sovereignty and accelerate the maturation of critical building blocks through test infrastructure and multi-year funding.
Priorities
- Materials and ageing
- Fuels and fuel cycle
- Modelling, data, HPC
Infrastructure
- Test platforms (irradiation, corrosion, thermohydraulics)
- Data sharing and common protocols
- Competitive access to major facilities
Governance
- Multi-year programmes and milestones
- Public-private partnerships
- Openness: publications and operating experience
Argument
R&D is not a luxury: without test infrastructure and data, we lose time relearning the same lessons.
