Safety of Small and Advanced Nuclear Reactors

Funds safety and demonstration work for small modular, advanced and innovative reactors, fuel cycles and energy-system uses.

OpenEuropean CommissionEU

Small modular and advanced reactors introduce new designs, fuels, services and deployment settings that need consistent safety evidence. Regulators, developers and researchers also need shared approaches for uses beyond electricity generation.

Projects can research and demonstrate the safety and viability of light-water SMRs, advanced modular reactors, innovative reactors and their fuel cycles. W…

Projects can research and demonstrate the safety and viability of light-water SMRs, advanced modular reactors, innovative reactors and their fuel cycles. Work may cover instrumentation, digital technologies, operating rules, industrial or district heat, maritime uses and integration into low-carbon smart energy systems.
