Material Science & Supply Chain for the Fusion Industry
Switzerland combines tritium expertise grown out of its watchmaking industry with highly specialized suppliers in mechanical engineering, materials processing and engineering — Cluster 3 bundles that offering into a single point of contact.
Custom or in series: solutions for the fusion industry
Switzerland is home to a tritium-processing industry that historically grew out of its watchmaking industry. With many highly specialized companies in mechanical engineering, materials processing and engineering, it offers extraordinary capability as a supplier. Cluster 3 brings together the specialized companies working in fusion research and, where possible, offers a single point of contact — or coordinates customer enquiries professionally and confidentially.
Fuel Cycle Management for the Fusion Industry
Every fusion power plant runs deuterium and tritium in a loop: injecting it, burning it in the plasma, recovering unused gas and newly bred tritium, reprocessing it, and injecting it again. Cluster 3 covers every stage of this cycle with specialized Swiss industry.
Good to know: Cluster 3 can't offer every solution and product itself — but it is networked closely enough that, together with industry and research, it can usually offer an optimal solution. Contact us today.

Where Cluster 3 comes together
Including the Fusion Fuel Cycle Workshop by smolsys at SOFT 2026 — one example of Cluster 3 activities.
Uniquely specialized knowledge, worldwide, networked
Cluster 3 connects Swiss research institutions with specialized industry know-how across the entire fuel-cycle value chain.

In the thick of it, or just watching?
Switzerland is internationally in “pole position” when it comes to handling fusion fuel — but the race has already begun. We can still decide, in the short term, whether to take part or just watch. The future needs your support.
