Chief executive officers from companies in the nuclear energy sector have called for Europe to implement an action plan that commits funding, mobilises capital and enables commercial deployment of fusion reactors “at pace”.

The CEOs said in an open letter that the European Commission should recognise fusion as a strategic priority for competitiveness, energy security and net-zero.

They called for an ambitious, technology-neutral, outcome-driven strategy and said the commission should back efforts to unlock private investment.

The CEOs, from companies including Proxima Fusion, the Fusion Industry Association, Focused Energy, DWE and Marvel Fusion, said Europe should establish a clear regulatory pathway for fusion, distinct from fission, and strengthen supply chains and workforce capabilities.
