There are plenty of sites that welcome new nuclear, usually any existing nuclear site would welcome more as its an economic engine for towns. The issue is it's just really poor and overly complicated technology, requiring miles of precision welds, the failure of any of which could cause big problems, and which must last for 50 years. It shouldn't be a surprise that this is hard to do well.

Nuclear energy is insanely efficient from a "materials that need to move around" perspective. That's why not having long term storage and just cobbling together short term on-site storage hasn't caused a crisis. The maintenance department at a plant generates more waste by volume.
Finding the space isn't the issue. Anywhere we could fit a couple container ships is fair game if you're looking for a national level solution. Politics is the problem. People are more scared of "magical glowing toxic waste" than normal toxic waste for whatever reason.
