“no real place to store nuke waste for 100,000 years”
You have to consider the tiny volume of the nuclear waste.
If the volume is so small then why not fly it into the sun? Cost, that’s why. And... the volume aint so small.
Starting in 1985, almost 100 short tons (91 t) of radioactive fuel were removed from the site. Planning and work was partially hampered by too optimistic views about the damage.[101]
