> So does your football field include the empty space necessary to keep the rods far apart If you are "aware" you might know that 99% of nuclear waste is low-level (contaminated hospital waste, rags, paper) or intermediate-level (cladding, concrete or chemicals from decommissioned reactors that are irradiated). These will never go critical. Even high-level radioactive waste doesn't go critical because the hot parts are either (a) valuable and get reprocessed into new fuel or (b) have short half lives and decay within a few month in the spent fuel pool of the power plants before being shipped away.

Yes, I am aware of the difference between high and low level fuel and the stew of different half lives of the constituents of higher level fuel. There's 47 k tones of high level waste in the US alone [1].So I think it's fair to assume that your 80 000 tonnes world wide was high level waste. Which has to be kept far apart from each other since they decay and at the very least generate heat. Therefore, apartness is an integral part of repository design. Yucca Mountain has a capacity for 70 000 tonnes. That is, its not big enough to store the world's waste despite nuclear power having a small fraction of the overall worldwide power production over the last 60 years.
