Hi Robin
Much of the energy in the rad waste is lost in the form of alpha particles, and
these have a very short range in solid matter.
One solution might be a "dusty plasma". I was surprised to find that
Wiki actually has an entry on this.

IOW convert the solid radwaste to a fine dust particulate - so that even
alpha particles escape and create lots of ions.
In a magnetic field, the charged polarities could be separated - just as
in other MHD devices. Of course, this would demand extreme measures to
insure that no leaks occur.
That cave in Nevada has already been dug, and would be a good place for
the plant to be sited.
