Without addressing the plausibility of the scenario initiation - one of the considerations of fuel storage is preventing that, especially with known seismic hazards - the release of energy could plausibly amplify the explosion. Dumping energy into air will heat it enough to produce explosive expansion; you've seen it happen, usually around tall dark clouds in the summer, when you can hear it for miles.

Arnie Gundersen has been all over the web and the news sharing his 
opinions on just what is going on.

I am not a nuclear engineer, but most of what he says seems plausible 
enough to me.  The actual claim was that a hydrogen gas explosion in 
Unit 3's fuel storage pond banged enough fuel rods into each other to 
initiate a prompt criticality, which resulted in another 
near-simultaneous blast, which made for a much larger event than it 
otherwise would have been.

The question I have of Mr. Gundersens and his assertion is, assuming we 
did have a prompt criticality in part of the fuel stored there, how does 
that result in such a violent explosion? That would get us a lot of heat 
and radiation, for sure, but how does that translate into an explosion 
unless there is some other vector present like water to flash into steam 
(and it does not look much like a steam explosion to me)?
