That is of course what the safest way of disposing nuclear waste would be : disperse it sufficiently, and spread it everywhere. That is, after all, what nature has been doing for billions of years, and it doesn't bother anyone because we evolved under background radiation levels. Accumulation is what makes these things dangerous, and what do we do ? We put them all together, behind a thin layer of metal, guaranteeing that a localized problem bad enough to pierce a 3mm layer of metal and a dozen centimeters of concrete becomes a complete catastrophe. But good luck defending that one politically, no matter how much you've got physics on your side.
