Question
Is fusion better than fission?
Fusion has a cleaner safety, waste, and fuel profile; fission is proven and deployed today. They're different tools — fusion aims to be the firm clean power fission promised, without its drawbacks.
Fusion and fission share the goal of firm clean power but differ sharply in safety, waste, and fuel — see how fusion differs from fission and fusion waste.
Questions & answers
Is fusion better than nuclear fission?
On several important measures, fusion's profile is cleaner: no chain reaction or meltdown risk, no long-lived spent fuel, abundant fuel, and no weapons-usable material. Fission's advantage is that it's proven, licensed, and generating power today, while commercial fusion is still being developed.
So which should we build?
It's not strictly either/or — both are firm, low-carbon options. But fusion aims to deliver what made fission attractive (firm, clean, high-density power) without the meltdown risk, long-lived waste, and proliferation concerns that have constrained fission's growth.
How does Kronos sharpen fusion's advantage?
By being low-neutron, Kronos further reduces activation and waste, and its fuel cycle produces no fissile material at all — extending fusion's inherent edge over fission.
