Nevada Test Site area has no better use.
The term "waste" fails to recognize the energy content of the material.
With new (and some not so new) reactor concepts, this shifts magically from a liability to an asset.
With no reprocessing, spent PWR fuel was loaded into a CANDU reactor in the DUPIC experiment.
In my opinion, if I had a few acres of dry casks, I'd build my next reactor capable of utilizing the source.
