[ RadSafe ] Icy future for Japan???

[Brennan, Mike (DOH)]

There are a number of plusses and minuses for the freeze wall concept.
It can be easier to ensure solid barrier (one with no leaks) than you
get by pumping concrete into the ground.  As long as you keep the
refrigerant pumping, it should be self-healing.  It is fairly easy to
expand in almost any direction.  When you are done with it, it is easy
to make go away.  

It does, however, require a lot of electricity, and pipes in the ground,
and probably some chemicals that can cause problems.  I don't believe
anyone's ever tried something this big before, and certainly not
expecting it to be in place for as long.

Radsafe:
     CNN News is reporting that Japan is looking at  freezing the ground
around the Fukushima reactors to keep the radioactivity from  reaching
the Ocean.  Is there no concrete in Japan???  Isn't dilution  the
solution to pollution????
