It's a BWR, the worst case failure mode looks something like Fukishima. Certainly a mess, but "set on fire" makes me think you're imagining another Chernobyl.

It's a BWR, the worst case failure mode looks something like Fukishima. Certainly a mess, but "set on fire" makes me think you're imagining another Chernobyl. BWRs don't catch fire like that. If something went very wrong, the reactor and containment buildings might pop and make a big mess, but it's not as though there's a thousand tons of graphite there to catch fire. It's not an RBMK. Edit: Actually it's a PWR, the other two reactors at this plant are BWRs. Still, similar worst-case scenarios.
