You appear to be reiterating an irrational position. I provided links to overviews of the topic; I strongly suggest at least skimming them. The quantity of unavoidable high level waste would appear to be sufficiently small that geological disposal is a cost effective solution.

The high level waste in question is not magically safe. Rather the various reprocessing and disposal methods have been extensively engineered and deliberated. At this point there is no cause to believe deep geological disposal in crystalline bedrock to be unsafe.

Less waste to deal with makes it safer, simply because you need to control and manage less material.

We also know how to get rid of it entirely, leaving only material that will decay to safe levels within hundreds of years. It's prohibitively expensive right now, but may be feasible in the future once technology matures.
