Domestic Isotope Supply Security
The breeder addresses three strategic isotopes at once — tritium, helium-3, and 14 MeV neutrons — as a domestic, sovereign supply platform.

Three isotopes, one platform
Supply security for strategic isotopes has usually been handled isotope by isotope. The breeder (Hyperion) is studied as a single platform that addresses three at once: tritium for stockpile replenishment, helium-3 for neutron detection, and 14 MeV neutrons for materials testing. Co-production from one machine is the organizing idea of this section.
Why 'domestic' is the operative word
Each isotope has a supply-security problem: tritium decays and must be replenished; helium-3 is scarce and inelastic; fusion-spectrum neutrons are historically hard to access. In all three cases, a domestic, sovereign source reduces exposure to concentration and interruption and puts the supply rate under national control.
- Tritium: a decaying isotope needing continuous domestic make-up.
- Helium-3: a scarce detection isotope with inelastic supply.
- 14 MeV neutrons: fusion-spectrum testing few facilities provide.
- One platform: co-production improves efficiency and resilience.
Honest framing
Why one platform, not three
Handling three strategic isotopes with a single platform is a deliberate choice grounded in their shared physics. The neutrons that breed tritium are the same neutrons available for materials testing, and the helium-3 arises from the very tritium the platform produces and stores. Because the outputs are physically linked, one machine can serve all three needs while sharing the most demanding infrastructure — separation, storage, and accountancy. Concentrating this capability in a sovereign asset improves both efficiency and resilience, which is the organizing rationale for treating the breeder as an isotope platform rather than a single-purpose source.
The breeder is a design and simulation study. Construction begins Q2 2027; FOAK first tritium is targeted for ~2030. Every output figure is a computed design target, not delivered supply. The supply-security case is real; the timeline and the honest gates are stated plainly.
