A Self-Sustaining Isotope Supply

Running the breeder generates a renewable stream of tritium, helium-3, and neutrons — isotope products that sustain themselves from abundant inputs.

Isotopes as renewable products

Operating the breeder (Hyperion) turns abundant inputs into a stream of otherwise scarce isotopes. From water-derived deuterium and lithium, the machine produces a roughly 4 kg/yr class of tritium, a helium-3 class near 1.97 kg/yr, and a flux of 14 MeV neutrons. These are renewable in the sense that they regenerate as long as the plant runs.

Why this is self-sustaining

The tritium sustains the plant's own fuel; surplus tritium decays to helium-3; helium-3 fuels the burner or serves other uses; and the neutrons breed the next batch of tritium. The loop feeds itself from inputs that are effectively unlimited, so the isotope supply does not deplete a finite resource.

• Tritium: sustains fuel and seeds new machines
• Helium-3: fuels the burner and supplies other uses
• 14 MeV neutrons: drive breeding and enable neutron services
• Inputs remain only water and abundant lithium

Honest gate

All output figures are computed design targets for a machine entering construction in Q2 2027, not measured yields, and no economic value is claimed. See what bred helium-3 can supply and the closed fuel cycle.

A loop that feeds itself

The isotope stream is self-sustaining because each product feeds the next stage: tritium fuels the plant and seeds new machines, its surplus decays to helium-3, helium-3 fuels the burner, and the neutrons breed the next tritium. Nothing in this loop depends on depleting a finite deposit; it runs on water and lithium, so the isotopes it yields are renewable in the only sense that matters for supply.
