The deepest mine in the world is 4km deep. There are only a dozen or so more than 2km deep. Going down 5-6km may be possible, but definitely not with "no issues

  You don't need to drill tunnels for people to walk in - just a borehole wide enough to fit a cylinder filled with nuclear waste. In fact, this very idea was already researched and test holes drilled - but of course was cancelled due to public opposition, even though we could get rid of our nuclear waste almost overnight using this method. Typical. https://en.wikipedia.org/wiki/Deep_borehole_disposal https://en.wikipedia.org/wiki/Deep_borehole_disposal

    Just running the numbers here. As per your Wikipedia article, current technology limits the borehole to 50 cm. That gets us 500 to 1000 m^3 worth of storage per borehole, assuming the lower 1km to 2km is used for storage. From this[1] page, as far as I understand, on a global scale the current amount of nuclear waste in need of such storage is 482000 m^3. So roughly 500-1000 boreholes to store the current waste inventory. Anyone got any ideas on how much it costs to drill a 5-6km 50cm hole?

      It costs something around 1000€ for a 6m well. Without the paperwork. But this is your usually drilling equipment for those depths.
