Where does the "1 mile down" come from? That seems more like based on emotion than on science / engineering. If it isn't, I'd like to see some of the tradeoffs of different depths.
I could imagine that drilling this deep might be the most expensive part, so if you could get away with, say, half of the depth, that would be quite the advantage.
What do we know about the safety tradeoffs of putting a reactor that far underground?
I'm not trying to shoot down the idea, it's just so unexpected that I feel I haven't even begun to think of the right questions yet.

- foxyv 2y agoI believe that the 1 mile down comes from the current proposed methods of disposing of nuclear waste. Essentially, you place the reactor in it's final resting place, removing the need to transport it to a disposal site. Depending on the site you would bury either deeper or shallower depending on the geological stability of the region. https://www.science.org/content/article/finland-built-tomb-store-nuclear-waste-can-it-survive-100000-years https://www.science.org/content/article/finland-built-tomb-s...
- schiffern 2y ago>the pressure of water at a mile deep is 160 atmospheres, the same as that found in the thick pressure vessel of the standard PWR. Technically it's about 1.03 miles, but they round to 1 mile. https://www.google.com/search?q=160+atmospheres+%2F+%281+kg%2Fliter+*+9.80665+m%2Fs%5E2%29+in+miles https://www.google.com/search?q=160+atmospheres+%2F+%281+kg%...
