Neutrons in demand

Fusion development is constrained by limited access to relevant materials testing. Commercial fusion requires components proven under high-energy neutron exposure, yet existing facilities cannot fully replicate fusion conditions at scale. As fusion timelines accelerate, access to high-flux neutrons becomes a decisive enabler.

Medical isotope demand is rising faster than supply. Precision oncology and ageing populations are driving sustained growing demand, while global isotope production remains capacity-constrained and vulnerable. Reliable neutron production is essential to secure supply and scale impact.

The world needs neutrons

Essential to progress in technology, healthcare, and industry, neutrons quietly underpin innovation with practical impact.

Access to high-flux, high-energy neutrons is becoming a decisive enabler of progress, supporting energy technology, enabling critical medical isotope production and strengthening research and industry worldwide.

  • Fusion development depends on neutron access.
    High-flux neutrons are essential for testing fusion materials, components, and lifetimes under realistic conditions.

  • High-flux neutron sources shorten fusion timelines.
    Faster, high quality testing reduces development risk and accelerates deployment of fusion technologies.

  • Fast neutrons allow isotope innovation.
    Fusion neutrons enable production of isotopes unobtainable with existing reactors or accelerators.

  • Reliable nuclear medicine requires reliable neutrons.
    Growing cancer care demand relies on sustained production of isotopes for diagnosis and therapy.

  • Europe is scaling fusion faster than neutron supply.
    Fusion programs are accelerating, while dedicated neutron capacity remains limited.

  • Strategic funding signals long-term demand.
    EU and national investments in fusion and advanced energy confirm sustained need for neutron infrastructure.

One solution for two critical bottlenecks

dante spherical tokamak

High duty cycle, long pulse operation and high neutron flux. Purpose built for materials testing and isotope production, using a scalable modular design with a minimal physical footprint.

A compact fusion neutron source

  • Compact spherical tokamak designed to deliver reactor-level fast neutron flux.

  • High neutron yield enabling production of a broad range of medical isotopes.

  • Large usable irradiation volume for materials testing and isotope production.

  • Flexible target configurations supporting simultaneous irradiation of multiple isotopes.

  • No uranium, no chain reaction — inherently safe by design with a simplified regulatory pathway.

  • Overcomes the scaling limits of fission reactors and accelerator-based systems for isotope production​.

Neutron production

Fuel Injection

Hydrogen isotopes, typically Deuterium and Tritium, are injected into the vacuum chamber as gas, high energy ions or high-speed frozen pellets.

Plasma Formation

Powerful magnetic fields and a central solenoid induce a strong electric current, ionising the fuel into a hot plasma.

Auxiliary Heating

External systems, such as Neutral Beam Injection or Radio Frequency waves, further heat the plasma to over 100 million degrees Celsius.

Magnetic Confinement

The unique spherical shape (low aspect ratio) allows for higher plasma pressure with lower magnetic fields, keeping the superheated fuel stable and away from the vessel walls.

Fusion Reaction

High-energy nuclei collide and fuse, overcoming the Coulomb barrier to create Helium and high-energy Neutrons (14.1 MeV)

Neutron Escape

Because neutrons have no charge, they are unaffected by the magnetic field and fly out of the plasma at high velocities.

Neutron Interaction

The high-energy neutrons penetrate the "blanket" or outer test sections of the tokamak.

Medical Isotope Production

Neutrons strike stable target materials to trigger controlled transmutation, creating life-saving isotopes for nuclear medicine diagnostics and therapy.

A healthier more sustainable future

Reliable isotope supply transforms diagnostics and treatment, eliminating delays, reducing costs, and expanding access to life-saving care.

Materials Testing

Neutrons bombard potential reactor materials and components to study radiation damage and durability for future fusion power plants, industrial materials and structures.

A step closer to usable fusion power

Accelerated materials validation unlocks faster fusion deployment, reducing uncertainty, costs and timelines for commercial energy.
