You can’t even name one, you just link to a bad researched video.

How do you know there isn’t an ice age in 100.000 years that completly changes the geological structure at those chosen points?

How do you know their copper tanks will last as long as calculated?

It is a silly long time you want to store highly radioactive material and you have to garantee that it won’t touch any water sources. That is impossible to proove - everything else is wishfull thinking or targeted propaganda.

Please name just one long term storage for highly radioactive waste. While you will fail at that, a second task: try to imagine a facility, that is able to store something safely for 1 Million years. If you can, you are not trying hard enough.

No, it can’t.

Except there aren’t any long term storage solutions for highly radioactive waste.

I wish I could look at it from a neutral position, but emacs is just too perfect to recommend anything else.
