Helium-3 Strategic Supply

Helium-3 is scarce and in chronic shortage; the breeder produces it, and the burner consumes it, which frames the whole sovereignty story.

Scarce and in demand

Helium-3 is a light, stable isotope used in neutron detection, cryogenics, quantum systems, and as a candidate fusion fuel. It is extremely rare on Earth, and demand has outstripped supply for years. This scarcity is the pivot of the Kronos energy-security story because the same isotope is both a product of the breeder and the fuel of the burner.

The breeder (Hyperion) produces helium-3 at a design point of about 1.97 kg/yr, partly through tritium decay (tritium decays to helium-3). This is a domestic production route for a material with no reliable domestic source. But the burner's helium-3 fuel demand is roughly 400x domestic supply per commercial unit, so breeding alone does not close the fuel gap.

Why lunar helium-3 enters the picture

Because terrestrial helium-3, including breeder-bred helium-3, cannot meet burner-scale fuel demand, the long-horizon supply story includes lunar helium-3, gated to roughly 2038-40. This is stated plainly as a dependency, not a solved problem: the burner's fuel supply does not exist at terrestrial scale today.

• He-3 is rare on Earth and in chronic shortage
• Breeder produces ~1.97 kg/yr, partly via tritium decay
• Burner He-3 fuel demand ~400x domestic supply per unit
• Lunar He-3 (~2038-40) is a stated dependency, not solved

The dual role of helium-3, product of one machine and fuel of the other, is the single most important structural fact in this section. It means the breeder's isotope value and the burner's fuel gap are not separate stories but two ends of the same material chain. Reasoning about one without the other, at its correct scale, is the most common way the supply picture gets distorted.

Design-and-simulation stage across the board.
