uhhh things arent going well at those nuke plants either

Abandon ship.
They initially suggested that the damage was limited and that emergency operations aimed at cooling the nuclear fuel at three stricken reactors with seawater would continue. But industry executives said that in fact the situation had spiraled out of control and that all plant workers needed to leave the plant to avoid excessive exposure to radioactive leaks.
If all workers do in fact leave the plant, the nuclear fuel in all three reactors is likely to melt down, which would lead to wholesale releases of radioactive material — by far the largest accident of its kind since the Chernobyl disaster 25 years ago…
“It’s way past Three Mile Island already,” said Frank von Hippel, a physicist and professor at Princeton. “The biggest risk now is that the core really melts down and you have a steam explosion.”
A Japanese cabinet minister confirms that part of the containment vessel itself in reactor number two has been damaged. Meanwhile, if you can believe it, a fourth reactor is now on fire and radiation levels have risen to the point where, in the vicinity of the plant, they’re actually a threat to human health. Which, of course, is another major problem since there are only so many workers with the know-how to perform the necessary tasks. Even if they’re willing to be rotated in or out, there may not be enough of them to staff the rotations.
And guess what? Even if a meltdown is averted — which now seems unlikely — the worst may be yet to come:
Even as workers race to prevent the radioactive cores of the damaged nuclear reactors in Japan from melting down, concerns are growing that nearby pools holding spent fuel rods could pose an even greater danger…
The threat is that the hot fuel will boil away the cooling water and catch fire, spreading radioactive materials far and wide in dangerous clouds…
The pools are a worry at the stricken reactors at the Fukushima Daiichi plant because at least two of the three have lost their roofs in explosions, exposing the spent fuel pools to the atmosphere. By contrast, reactors have strong containment vessels that stand a better chance of bottling up radiation from a meltdown of the fuel in the reactor core.
It would take days or weeks for the spent rods to boil off so there’s time to deal with this problem if workers can get back into the plant. But if they can’t due to radioactivity — what then?
A nuclear engineer tells the Times that spent rods catching fire would actually be worse than a meltdown. If I’m understanding it correctly, it would be the equivalent of a giant dirty bomb going off.
