    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    You lack understanding of the interrelationship between the reactor, drywell, and torus. As far as #2's explosion, I'll stick with this, sourced multiple times in this thread: "it is realistically assumed that without operator action, reactor vessel pressure control over the long term would...

    Japan Earthquake: Nuclear Plants at Fukushima Daiichi

    It seems to have been a blob for quite some time now... Wouldn't you want to keep water in the drywell to help cool the RPV, which would in turn help to keep the corium blob cooled? I believe that could prevent melt-through, but have no resources to back up such a claim. No measurable water...
