All nuclear waste ever produced in the US could be stored in an area the size of a football field
That was is just the fuel and fuel is just a small part of all the waste.
Yes it is very radioactive but that doesn't mean that the rest can be stored on a landfill. It is still so radioactive that we don't have a proper solution for it's storage. Only because the fuel is SO MUCH MORE radioactive, doesn't make the rest disappear or the football field argument valid in any way.
