Quote from D3adsI'm praying that the reactor doesn't explode... it doesn't bare thinking about what would happen if that occured.. *shudder*
It's not going to explode. Hydrogen gas might explode, except that there's no longer a roof to keep it in so it builds up. The bad thing with the reactor is it melting into a big solid uranium puddle in the bottom of the reactor, which would be pretty difficult to cool and impossible to fix, so they'd just bury it in a sarcophagus. This isn't very likely of happening either. The main thing they're worried about is the spent fuel rod pools becoming dry, resulting in the spent fuel rods overheating, which would oxidize the rods and release a bunch of scary radiation.
