NUKE


Yes, Nukes                                             
                                                            
         Perhaps I should hesitate to rehash                
         the nuke debate of the 70s, but I'm               
         a firm believer that nuclear power 
         has gotten a bad rap.

of a political problem than a
technical one.  Radioactive

concentrating it, and        
stashing it in a site chosen        ((I need to verify

problem" because it's    
just accepted that the    
bulk of the waste will              
be pumped into the    
air.                     
                        
And this includes
radioactives embedded in
the coal.  If coal plants
had to meet the same    
standards as nukes, they'd
all be shut down.
                                  

-------- 

Consider just as a
thought experiment, dumping
the waste in the ocean.  If
your canisters are good,
maybe it gets buried and you
don't release anything.  If
they leak somehow, and it
gets into the sea water,
there still wouldn't be any
measurable change in the
concentration in the stuff
that's there already.

This probably isn't the right
way to do it, but I take it
as the baseline: we can
clearly do better than this.

(Mander's idea that we need armed guards           (see MILCOMP for ref).
on nuclear waste strikes me as kind of
whacky.  Does he expect a terrorist
attack in the southwest US, by people
equipped to transport massive amounts of
hot stuff without getting fried, who have
the capabilities to refine spent nuclear
fuel enough to squeeze enough weapons
grade material to make some bombs?  If
this was doable, I would guess the
material wouldn't be called "waste", it'd
be recycled and reused as fuel.)
          
(Try this factoid for a reality check:
nuclear fuel is enriched about 5%.
Weapons grade material is enriched about
95%.  Two different animals.)

Beckman's book "The Health Hazards of _Not_ Going Nuclear" 
isn't bad.  Here's a couple of paragraphs from 
p.102, Ch.4 "Waste Disposal":

       The much used rhetoric about wastes remaining
    "radioactive for thousands of years," while perfectly
    true (the halflife of plutonium 239 is 24,400 years), is
    quite misleading and largely meaningless... the longer
    the halflife of an isotope, the less intense it's
    radiation.  Arsenic, which is not radioactive at all,
    has an infinite halflife, and indeed, while plutonium
    will be around for a long time, arsenic will be around
    forever.
       Nor is the point about arsenic (for example) a cheap
    trick of demagoguery.  As Prof. B. Cohen of the
    University of Pittsburgh has pointed out, arsenic
    trioxide is a poison used as a pesticide.  It is not a
    very commonly used one, but more of it (in weight) is
    imported every year than all the nuclear wastes would
    amount to if all US power were nuclear.  Arsenic
    trioxide is about 50 times more toxic than plutonium
    when ingested (for plutonium being "the most toxic
    substance known to man" is more melodramatic piffle),
    but the main difference compared with the threat of
    wastes is this: Nuclear wastes, when there are enough of
    them, will be buried deep underground in carefully
    chosen geological formations.  But the arsenic trioxide
    is dispersed in random places on the earth's surface,
    mainly where food is grown.  Long after the nuclear
    wastes have decayed to negligible levels, it will still
    be around in the biosphere.
