No. Volcanoes are no good. Too volatile, unpredictable.
Using concrete and steel casks, the contained radioactive waste should be lowered into a deep-sea trench along a subduction zone, preferably the Aleutian Trench, which I believe is in U.S. territorial waters. There the radioactive waste can be RECYCLED under the North American Plate.
This satisfies the three criteria for safely disposing of radioactive waste: time, distance, and shielding. It won’t reappear for millions of years and in the meantime will be underneath miles of the earth’s crust. Difficult to get much better than that.
I’d like to see proof that stuff placed there would actually get subducted (is that a word?) before trying it with nuclear waste.
It’s possible though, that in a few more generations we may wish we hung on to the stuff.
Re putting radioactive waste in a deep sea trench. It won’t work. Didn’t you see the movie “The Beast from 30,000 Fathoms”? Nuclear waste made a small sea creature massive and he ate a New York Cop, a bathyscape, and destroyed a roller-coaster.
Just image 50 ft. long sea worms attacking New York City. Now, if we could get them to attack Philadelphia, Chicago, Detroit, San Francisco, Hollyweird, Seattle and Portland, then I might change my mind. Sort of like the worm attack scene from “DUNE”.
Worms love liberals. Taste like chicken. An appropo analogy.
Do you have a background in geology? Sounds like it.
We have the ability to dig holes that are miles and miles deep, not only that we have many abandoned mines which are empty and pose no threat to any water table. throw the waste down there and fill it up with concrete and dirt.
