Real talk, why can't we just launch that shit into the sun? Obviously, I understand the risk of a rocket filled with spent fuel rods exploding is low Earth orbit and the weight to cost ratio, but are there other reasons?
It's insanely more expensive than any of the other options, even the long-term storage deep down underground with further burial and complete abandonment of the location in a way that would make the location as unremarkable as possible, preventing future generations developing interest to potential markings.
Tom Scott has a great, rather concise video about that. It's not really just ground, but rock, making it even more secure and unaffected, especially given that the waste is first sealen into special containers.
The waste is vitrified, meaning that it's encased in what's basically solid glass.
Basically to put something in the sun youโve got to bring it to a near-standstill relative to the sun. You have to slow it down from the speed Earth is orbiting at (2 * Pi AU/year) to almost zero. It takes a ton of rocket fuel to do that.
That plus the danger you mentioned makes burying it the cheaper and safer option.
It's literally easier to launch something outside the solar system than launching it into the sun.
