From what I'm reading of the Japan Times things are not looking good for them or the rest of the world. If this isn't a time for swift world action then I don't know when is. There are so many things going wrong in Japan at the moment I see no good outcome and this will affect all of us if we don't rally the best minds in the world.
Here's a thought if the details could be worked out. Pump liquid nitrogen into or near the reactor core to bring down the temperature. There is the danger of course of making the metal brittle causing it to crack but I think seeing as how the containment structure is some six inches of hardened steel it just may have a chance of working. The problem would be getting that much liquid nitrogen to the location. Maybe by ship?
According to the Times all personnel have been evacuated from the plant. It has been deemed unsafe for any workers to be in the area. Elevated levels of radiation has been recorded as far away as Tokyo 150 miles away.
So you have about 10 days depending on the weather and when a meltdown will occur to decide what you will do. Will you stay and try and ride out the fallout or head for some safer area? Anyway you look at it this will affect us all in one way or another. 750 rads is enough to give you cancer down the road. And I'm sure when the estimates from my last post were done they were a best case scenario.
