[ RadSafe ] Icy future for Japan???

[JPreisig at aol.com]

Radsafe:
 
     If this project were in the USA (thankfully  not!!!), the EPA would 
probably require a passive barrier system (not much human  intervention 
allowed) and the system would have to remain in place for 300 or  more years.
Concrete might pass these tests.  I doubt the freeze wall concept  would 
pass these tests.
 
    Even if there were slight leaks in a concrete barrier  system, the 
ocean would still provide considerable dilution.  However, the  project is in 
Japan, and they can do what their regulators allow/approve.
 
    The Japanese should probably head up to Chernobyl and  see the 
Sarcophagous around the Chernobyl reactor, and engineer a solution from  there.  My 
heavens, when will fusion come online???

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.

And concrete  doesn't melt!

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????
