Thanks again to all for the extremely interesting discussions of facts here, it looks like this is an island of sanity on the web...
I went through a bunch of pages here, but could not find anything again about the Pu that was measured. Has the situation evolved?
I also found an...
A very quick and dirty back of the envelope:
length of beach, let's say 500m on both sides of the factory, makes 1000m
area up to 500m from shore
average depth between beach and 500m distance: 100m
makes a volume of 5x10^7 m3
If you consider dumping for example 5000m3 of highly...
Does the US army not have transportable desalination units? A quick google search turns up there are units for flatbeds that have capacities of 140'000 GPD which I assume to be gallons per day and should be able to cope with generating enough water.
Data plots
I just stumbled upon someone who plotted various variables over time for reactors 1,2, and 3 (pressures, water levels,...), this might be helpful to understand how things evolve in the reactors:

"...The radiological toxicity of reactor-produced plutonium far exceeds the
chemical toxicity of this heavy element..."

Concerning the availability/non availability of data, there is an effort to collect unofficial (and most likely non calibrated) radiation data in Japan using private Geiger counters, don't know if it helps figuring out what is going, but haven't seen it mentioned here...
I found this forum searching for discussions about facts of what is happening in Japan, and have been reading it for nearly a week now. I am glad to see so many people interested in what actually is happening instead of the scare mongering done by the media...
I wanted to add a perspective on...
And here they say it's the SFP that has reached 400C:

"Another negative development in the world’s worst nuclear crisis in a quarter of a century is that the temperature at the spent fuel pools at Reactor...
Here is some information about the spent fuel stored in TEPCO facilities:

Maybe this helps you to make a better guess at what is going on right now.
