Question

Is fusion energy safe?

Fusion cannot melt down or run away — and Kronos's low-neutron design goes further.

Why

Yes. Fusion needs a narrow window to proceed and stops the instant conditions leave it — there is no chain reaction to run away, and no meltdown risk.

01

No runaway

Unlike fission, there's no self-sustaining chain reaction; lose the conditions and fusion simply stops.

02

Low-neutron

D–³He at fₙ 5.44% means far less activation than D–T, and scheduled-replacement waste near zero.

03

Honest limits

Public-dose and waste requirements are published with the conditions that make them achievable.

Is fusion energy safe? +
Yes. Fusion cannot melt down or run away — it needs a narrow window to proceed and stops the moment conditions leave it. Kronos's burner is also low-neutron, with scheduled-replacement waste near zero.
Is fusion radioactive? +
Fusion produces no long-lived high-level waste like fission. Kronos's low-neutron burner (5.44% of power as neutrons) minimizes activation; requirements are shown with their conditions.
Can a fusion plant explode or melt down? +
No. There is no chain reaction and only a tiny amount of fuel in the plasma at any moment; any disturbance stops the reaction rather than accelerating it.
