The more dangerous stuff burns itself out quickly (short half-life), and the longer-lasting stuff is not very dangerous given the type of radiation it is and can be blocked quite easily
So, probably bury it deep enough with little external sign that it's actually there, and if it is actually discovered it won't be that big of a deal:
> The main concern associated with spent nuclear fuel – radioactivity – diminishes with time.
> About 40 years after it's done making power, the heat and radioactivity of the fuel bundle will have fallen by over 99%.
> About three containers are needed to store the quantity of fuel that is removed each 12-24 months; the space taken up by even a 60 year plant life is less than is needed for a Wal-Mart even without any efforts to efficiently stack the containers.
