Weight is a way to make the problem sound worse than it is, because nuclear waste is so incredibly dense. It's not enough to be a big deal yet. Dumping it deep into the ocean is an option, but it's only going to happen to waste that doesn't have potential uses first.

nuclear waste is so incredibly dense

Yes and no. Most current fuels are Uranium or Plutonium. Both between 19 and 20 g/cm^3^. For reference, liquid water is approximately 1 g/cm^3^. Unspent fuel is a similar weight to gold.

"Spent" U~238~ is usually around 96% U~238~. If we consider the remainder a rounding error and assume all 60 tonnes is 60 million kg of U~238~. That will give us a very rough estimate of 3,000 m^3^.

Also worthy of noting are other wastes that comes from mining and refining.

There is much waste already. The "spent" waste is too radioactive to safely re-refine until later.
