I'd love you to be correct, but I don't think so.

Firstly, I've never heard of a lightweight structure being built around the secondary containment to keep the rain off. There is no point, The secondary containment by it's nature is a robust concrete building that needs no protection from the elements.

Secondly, The footage of the explosion appears to show what it quite obviously a concrete building exploding:



A lightweight building would blow apart and reveal the flames of the actual explosion. The scene above looks more like the cloud of grey dust one would expect from a heavy concrete building being blown to smithereens.

You so know it

It still doesn't necessarily mean a large release of radioactive material. As I said before, the reactor vessel may well be intact. That's what they're saying at the moment.

However, the mere fact of the secondary containment being blown away would probably make this second only to Chernobyl in seriousness.

They have major problems with all off them.

Well no, but most of that lot are dead.

Wow, a 60 year old man has been rescued today after being swept out to sea on a section of his roof. He was picked up 15km offshore.

New Scientist has this about the nuclear power stations and associated blasts and problems:

Very interesting. Very level headed.

In summation:

....an official at Japan's nuclear safety agency rated the incident a 4, according to the International Nuclear and Radiological Event Scale. Three Mile Island was rated a 5, while Chernobyl was rated 7 on the 1 to 7 scale.

NASA geophysicist Richard Gross calculated that Earth's rotation sped up by 1.6 microseconds. That's because of the shift in Earth's mass caused by the 8.9-magnitude earthquake. A microsecond is one-millionth of a second.

I've just been watching NHK (Japanese TV with an English translation on Sky 516) and the devastation is extraordinary. Looking at the scale on a map, the tsunami hit an area at least equivalent to the coastline between Bournemouth and Hastings and possibly a lot longer than that, though hopefully less densely populated.

Quake now been upgraded to a 9.0 using all the latest data they have

Watching some of the devastation with the kids yesterday. DS turned to me and said how awful it all was, just like something from a film but you never expect to see things like that in real life. Sympathies to ev1 over there and the friends and relatives abroad

I think if I lived in san francisco I would be moving out now. What with the christ church earthquake then this there has been an awful lot of movement on that pacific plate.

I can see this becoming an iconic image for the anti-nuclear lobby:
