There are superior solutions to vitrification. Synroc [1] is technically far superior as it puts the long lived isotopes into mineral phases in which they are stable, as opposed to metastable glass.

Once stablised as synroc it is simply a matter of storing the waste. Storing above ground (i.e. in a shed) seems to me to be a better solution than pursuing geologic disposal, given the waste is now stable, and can be easily monitored.

That is pretty cool stuff.
