Previously in this thread I excluded the possibility of an explosion. I was wrong. Most of this is speculation as to what happened, I might be
The containment building is supposed to be able to design overpressure from a build up of steam. TEPCO claimed the steam was successfully vented away
from the reactor. If it wasn't, then this could of caused the containment building to break. I am unsure if it could cause it to explode.
There's that possibility. And there's this:
The fuel assemblies are made up of lots of fuel rods bunched together. The fuel rods are made from metallic Zirconium and inside are Uranium Dioxide
pellets of fuel. If the reactor cannot be cooled adequately and the fuel gets too hot, eventually the Zirconium fuel cladding will react with the air
(or water? I forget) in an exothermic reaction, raising the temperature even higher. Hydrogen gas is evolved from this reaction. Hydrogen gas is
explosive especially in confined space like the containment building. Normally
be recombined with oxygen forming water
via hydrogen recombiners, if this does not occur a potentially dangerous mixture could occur. This is the only
thing that I could think of that
could possibly cause the reactor building to explode like that.
But if it was Hydrogen gas it would mean that all efforts to cool the reactor failed, and reactor is extremely hot and probably melting down as we
speak. And even worse it will be exposed to air. In other words, the # has hit the fan.
As far as I know, the wind is blowing the radiation away from Japan towards the US, but it can dissipate over the pacific ocean before then. The
reactor also, unlike Chernobyl, isn't out of control, and unlike Chernobyl shouldn't be on fire.
But again, I might be wrong.
