Comparison
Low-neutron vs aneutronic fusion.
'Aneutronic' means zero neutrons — a marketing word more than a machine. Kronos is honest: the burner is low-neutron, at 5.44% of power as neutrons — a few percent, small, and not zero.
Side by side
A few percent is small — and it isn't zero.
'Aneutronic'
The ideal claim
- Implies zero neutrons — no activation, no shielding
- True near-zero needs helium-3 fractions that don't close on this machine
- Often used loosely in fusion marketing
- Kronos does not claim it
Kronos
Low-neutron (honest)
- D–³He at the design point: fₙ 5.44% of fusion power
- Far below D–T — a much cleaner wall and waste profile
- Scheduled-replacement waste near zero; still needs some shielding
- We publish the number, not the buzzword
Near-aneutronic operation would require a redesigned machine — a named option, not this design. We say so.

Conceptual design and simulation study; the integrated Kronos machines are not yet built, and certain results are requirement-class. No financial figures are published on this site.
