Helium-3

A rare, light helium isotope; the burner's fuel and a strategic material.

Helium-3 is a rare, non-radioactive helium isotope. It fuels the D–³He burner and is strategically valuable for quantum and medical uses. The breeder co-produces about 1.97 kg/yr, giving Kronos an internal supply path.

Helium-3 is a rare, non-radioactive isotope valued for quantum computing, neutron detection and medical imaging as well as fusion fuel. The breeder co-produces about 1.97 kg/yr/yr, giving Kronos an internal terrestrial supply and a strategic position in a genuinely constrained material — value Kronos frames as strategic rather than near-term revenue.
