Go on, my understanding is that the "explosion" was basically a steam pressure explosion which blew the top off of the reactor, if that is incorrect do you have a reasonably easy to understand source?

There were two explosions - first was a steam explosion followed 2 or 3 seconds later by another more powerful explosion - with the cause of the latter still being debated. However, one theory does describe it as follows: "However, the sheer force of the second explosion, and the ratio of xenon radioisotopes released during the event, indicate that the second explosion could have been a nuclear power transient; the result of the melting core material, in the absence of its cladding, water coolant and moderator, undergoing runaway prompt criticality similar to the explosion of a fizzled nuclear weapon." http://en.wikipedia.org/wiki/Chernobyl_disaster#Experiment_and_explosion http://en.wikipedia.org/wiki/Chernobyl_disaster#Experiment_a...

  Arnie Gunderson from Fairewinds makes the case that the explosion in fuel pool of Unit 3 at Fukushima was a detonation (faster than the speed of sound) and not a deflagration (speed of sound). A plausible reason was a initial hydrogen explosion in the pool distorted the fuel and initiated a moderated prompt criticality. http://www.fairewinds.org/gundersen-postulates-unit-3-explosion-may-have-been-prompt-criticality-in-fuel-pool/ http://www.fairewinds.org/gundersen-postulates-unit-3-explos...
