Re: A real solution

Hi All,

What I remember from my days fighting the Anti-Nukes in Switzerland, it takes
between 600 and 900 years (depending on the reprocessing method used) for the
health risk posed by the activity in a spent fuel element to decay to that of
an ore that you could find in Switzerland.  And there are no useful fissile
ores in Switzerland.  I remember there were a lot of exposure assumptions in
that risk calculation, but it may help you get an idea, in particular that this
time is not measured in multiples of 25,000 years!

Best regards

Fritz
