Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
There was a hydrogen explosion in the building of reactor 1, but outside the reactor. The explosion was from hydrogen released form the containment vessel when venting steam to reduce the pressure. The explosion blew off the top of the building only. The similar explosion around reactor 3 looks like the building is reduced to rubble. The explosion around reactor 4 which also affecter the entire building took place because of hydrogen released from the spent fuel pool, not from the reactor which had had all its fuel moved to the pool for scheduled maintenance.

The explosion in reactor 2 was in the "torus" wetwell below the reactor. But the outer shell of the building is relatively intact.

So, in what may be my last act of "advising", I'll advise you to cut the jargon. -- My old PhD advisor, to me, 26/2/11
