Horizon Nuclear-Powered Shipping Roadmap

Funds a €2M coordination action that maps whether nuclear propulsion could be safe, viable and responsible for commercial shipping.

ScheduledEuropean CommissionEU

Nuclear propulsion could reduce greenhouse-gas and air-pollutant emissions from commercial shipping, but its feasibility depends on more than reactor technology. This scheduled Horizon Europe Coordination and Support Action funds one €2 million project to assess the technical, economic, environmental, legal and social conditions for possible deployment.

The project should evaluate SMRs and other

Develop a research and innovation roadmap for nuclear-powered commercial shipping, covering SMRs and other advanced nuclear technologies. The action assesses technical feasibility, ship integration, lifecycle costs, infrastructure, safety and security, environmental and marine impacts, waste and disposal, damage scenarios, regulatory and legal gaps, crew training, skills and social acceptance. It maps national, regional and international regimes, informs EU climate and air-pollution plans, and coordinates industry, research, NGOs, public authorities, IAEA and IMO perspectives under the ZEWT Partnership.
