Do you know what their current thoughts are on this?
Right now with the yahoos running the US, Japan may be our best hope. Apparently Steven Chu was recommending that explosives be used to blow holes in the reactor early on so they could get more water into them. Trying to find that link right now. Will post it if I find it.
Messages show conflict within NRC after Japans earthquake and tsunami
The NRC e-mails reveal disagreement about how to advise the Japanese. The NRC staff chafed at some unorthodox advice coming from an ad hoc group of scientists assembled by Energy Secretary Steven Chu. Famed physicist Richard Garwin, one of Chus group, proposed setting off a controlled shaped explosion to break through the concrete shield around the primary steel containment structure to allow cooling water to be applied from the outside. One NRC scientist called the idea madness.
Another idea from the Chu group was to attempt a junk shot a variation on what some engineers proposed to stop the oil spill in the Gulf of Mexico to plug leaks of radioactive water from Fukushimas nuclear reactors into the sea. When using a mixture of sawdust, newspapers and other junk failed, Japans Tepco ultimately used a compound known as liquid glass.
Apparently the last people we need helping on this situation right now are those tasked with the responsibility. Where is Red Adair when you need him ?
