I would like to advocate again against storing nuclear waste in a centralized repository. A community willing today to host it may want to change its mind, which will be practically impossible. Besides, there is a better, proven way, to deal with radioactive material in a safe way: dilute it.
We did not invent radioactive materials (except for some short-lived synthetic elements); all we do is to concentrate ore to be useful for our activity. In the diluted form, in which it occurs naturally, it is harmless.
So, I suggest using waste from other mining activity to mix with nuclear waste, and spread the mix over large areas, ideally underground. I hope this helps.
Truly yours, Sorin Schwimmer
