I can't understand the difficulty governments have disposing of nuclear waste materials. Can't they just put it
back in the same place they dug it up from in the first place?|
Somewhere out there, dotted around the map, are uranium mines where they dig up low-level radioactive bearing ore.
Putting the "spent" radioactive materials back in the original hole is surely no more dangerous to that area, or
to those people, or to the environment, than the original radioactive ore that came out of it?
And if my un-scientific assumptions are incorrect, and the refined nuclear material has been brought to
a higher level of radioactivity than the original ore, then it seems only fitting that it goes back to where it
came from so that those land-owners who profited by its extraction should be the ones who have to deal with the
dangerous legacy that they themselves instigated.

Each year the world’s 441 nuclear power reactors create enough spent fuel to fill a football field. That’s about
10,500 tonnes of heavy metal. This waste is thermally hot and can stay radioactive for thousands of years. Because
it is solid and does not readily dissolve in water, the fuel wastes are typically stored in water pools on site at
the nuclear reactors for many years.
But permanent disposal places are needed. Scientists warn that the ongoing storage of spent fuel is not sustainable
for the long years needed for the waste to decay and lose its radioactivity. Right now only one permanent disposal
facility exists in New Mexico where long-lived radioactive waste from United States military programmes is
carefully packaged and cocooned in tunnels deep underground, in what is called a geological repository.
