Fukushima Nuclear Blast?

The first visible fire in Unit 3 is seen at about the place in the building where the spent fuel pool is located. I've also seen a report that states a piece of spent fuel rod was found about 1 mile away form the Unit 3 building after the blast.

This news is not good and may be indicative that the Japanese authorities are not being very forthcoming with news and analysis of this disaster.

If mistakes are to be learned from, they need to be part of the international nuclear industry's dialog as soon as possible.
