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.
