Why Fusion Is Inherently Safe

Fusion's safety is not a system bolted on — it is physics. There is nothing to run away.

Chain reaction

None

Fuel in machine

Seconds' worth

Meltdown pathway

None

A fusion plasma holds only a tiny, continuously-supplied amount of fuel and depends on precisely maintained conditions. Anything that perturbs it — a power loss, a leak, a fault — makes it cool and extinguish within seconds. There is no chain reaction, no critical mass, and no stored energy that can drive a runaway.

The burner adds a further margin: as a linear mirror it has none of the tokamak's disruption failure mode.

Fusion's safety is physics, not a bolted-on system: the plasma holds only seconds of fuel and depends on precisely maintained conditions, so any fault makes it cool and stop. There is no chain reaction, no critical mass and no stored energy to drive a runaway — and the linear burner additionally lacks the tokamak's disruption failure mode.
