  • To add to this: A certain type of Soviet submarine used a lead-bismuth alloy as coolant for their reactor. The coolant solidifies at ambient temperature so it had to be heated indefinitely by some way or another or else it solidified and trashed the reactor. I don’t think any of them exist anymore since Russia wasn’t able to afford sustaining the giant navy after the Soviet collapse.

    Just goes to show how insane nuclear submarine engineering is, or was at some point.
