Ths is a massive misunderstanding of the technology. First of all, the amount of hydrogen in the reactor is tiny. The magnetic confinement severely limits the density of the plasma. The inner containment vessel is a ultra high vacuum chamber. The chemical energy that would be released by a reaction between the hydrogen in the reactor amd oxygen from the air would be less than what is released by popping a hydrogen filled balloon with a lighter.

The truly concerning failure modes would be related to release of radiation or activated materials. But that would require damaging the reactor in ways that the reactor is incapable of imparting on itself.

Overall, the technology is remarkably safe.

You are ignoring that the plasma would ignite the O2 in the air. You are also ignoring what happens when several hundred MW of energy (at about 1,000,000C) under pressure is released instantly. Anytime you have a powerplant with enough energy to be economically viable, releasing that energy at once will be a problem. Even FF PPs can explode quite violently.

Thanks for the correction. If you're breeding lithium in the walls, might that be an incendiary concern?
