One thing to keep in mind as this progresses is that this is not a nuclear disaster, it is a natural one. One of the six largest earthquakes in history hit this structure followed by a tsunami and aftershocks. It's shocking that the entire area isn't GLOWING by now, much less that they've been able to handle everything as well as they have.

Some lessons learned: Keep the generators on the ground level, and have solar back-up to run the cooling system. Triple redundancy. If the plant had electricity this never would have happened. Also, I think keeping spent fuel on site should be re-examined.
