"That a 10,000 year storage solution was nowhere near long enough to inculcate the Earth from the true shelf-life of the waste, which is realistically thought to be dangerous for many times that length of time." With some definition of "dangerous" sure. After just few hundred years, it's only slightly more dangerous than naturally occurring uranium. The other difference is that natural uranium is dispersed more and guarded less. "Final disposal of high-level waste is delayed for 40-50 years to allow its radioactivity to decay, after which less than one-thousandth of its initial radioactivity remains, and it is much easier to handle. --- After being buried for about 1000 years most of the radioactivity will have decayed. The amount of radioactivity then remaining would be similar to that of the corresponding amount of naturally-occurring uranium ore from which it originated, though it would be more concentrated."
