Again, nonsense.  The waste from current reactors is mainly uranium 238 (~95%), one of the isotopes coming out of the ground when uranium is mined.  So putting it back in the ground is, well, kind-a appropriate.  However, that would be stupid!  Since one has the uranium 238, which can be used to fuel reactors, why throw it away?  Use it in one of the "new" designs (most have been known about since the beginning off the nuclear power age) and one is left with true waste with at most ~30 year half lives.
