For instance, its only me thinking that billions spent on yucca

long-term economic and environmental sense.

Not a good example. We would *still* have to deal with the existing
high-level wastes somehow, no matter what other sources of energy we
find.

I don't see what is wrong with just a big concrete structure in the middle of
Death Valley, glassify the waste and store it there.

Even better:

Crush the wastes into a fine powder. Mix at a 1:10,000 mass ratio with
concrete (and at a 1:50 mass ratio with non-radioactive powder of the
same basic elementary materials), and form into 50 cm cubes. Then cast
those cubes into the centers of 1 meter cubes of straight concrete. You
now have a large structural block of concrete with a virtually
undetectable and essentially unextractable radioactive component. Use
those bocks, in their hundreds of thousands, to build up artificial
island, dams, bridges, walls.
