Dave Fawthrop said:Ouch! Real,engineers, as against academics, never try for a "1st class
job" they do the job well enough.
That's just semantics. To me, nuclear waste disposal done "well enough"
*is* a first class job. The module I did was taught by a very
experienced geophysicist with many years Real World experience working
for commercial companies. He didn't present us with conclusions, merely
facts from which we could draw our own.
Quoted message said:The problem with that argument is background radiation. We and our
ancestors have dealt with cosmic rays, and granite rocks for billions of
years. Increasing the levels of radiation by a fraction of background is
IMO acceptable.
The problem with the above is it dismisses a lot of very important
issues such as erosion over thousands of years exposing incredibly toxic
material, water table movements over that time frame leaching said
incredibly toxic material, and excessive heat build up that a repository
can't handle, by only assuming a minor increase in background radiation
as the only problem. It's not that simple, by a long stretch.
