Yes let's just destroy a piece of nature before we even discovered it....at least it saves us the time of documenting it.......

Bad Idea, the stuff needs to be stable for 10s of thousands of years. And we have never performed such longtime stability measurements of e.g. the glass (ceramic) that you are talking about.
I think we should not take these kind of risks.

Actually, I agree with eppie on this one. :) I'd rather we keep it in a geologically stable deep dry place where we can keep an eye on it. Also, our spent fuel is not really "waste" and some day we might want to reuse some of it for other purposes.

"In March 1977, fear of nuclear weapons proliferation (especially after India demonstrated nuclear weapons capabilities using reprocessing technology) led President Jimmy Carter to issue a Presidential Directive to indefinitely suspend the commercial reprocessing and recycling of plutonium in the U.S. Other nations, have not followed suit and continued to reprocess spent nuclear fuel." source

The mountains of U238 we mine and don't use should be restored below ground until we decide we want to use it in breeder reactors.
