What are the benefits of storing nuclear waste in subterranean salt mining caves?

The main advantage is that since the salt has been in its deposit for millions of years, there could not have been groundwater flowing through the deposit for at least that long. If there had been, it would have carried the salt away. So, if nuclear waste is placed inside the salt bed, chances are good that groundwater won't carry it anywhere else. The nuclear waste will decay away to nonradioactive elements before it leaves the salt deposit.
