Question
Is fusion energy clean?
Fusion emits no CO₂, and Kronos's low-neutron burner minimizes waste too.
Why
Yes. Fusion produces no carbon emissions and no long-lived high-level waste. Kronos's D–³He burner is low-neutron — 5.44% of power as neutrons — so activation and scheduled waste are far lower than D–T.
01
No CO₂
Fusion is carbon-free at the point of generation.
02
Low-neutron
Fewer neutrons than D–T means less activation of the structure.
03
Near-zero scheduled waste
The burner's replacement-component waste is near zero over its life.

Is fusion energy clean? +
Yes — fusion emits no CO₂ and produces no long-lived high-level waste. Kronos's low-neutron D–³He burner (5.44% of power as neutrons) further minimizes activation and scheduled waste.
Does fusion produce radioactive waste? +
Far less than fission and no long-lived high-level waste. Kronos's low-neutron design keeps scheduled-replacement waste near zero; requirements are published with their conditions.
Is Kronos fusion aneutronic? +
No — it's low-neutron, not aneutronic. At the design point 5.44% of power comes out as neutrons: a few percent, small, and not zero.
