Man, they just can't get enough cooling water into those reactors. Basically, that is the crux of the problem.. The #4 one started on fire again, but apparently it went out on it's own, some brave dude could take a look, was mentioned. They think the fission rods that are in the storage pool there have had the water level go down and it is exposing them to the atmosphere, and the subsequent heat creates explosions, possibly from Hydrogen build up. Everyone has become an expert in nuclear fission over the last couple days.
My wife is scrubbing the tub now. We do have some rivers close by for drinking water, if no other source available.
