If it's using gravity, what happens if this whole reactor gets tilted? What happens at 10 degrees? 45? 90? 180? Are there any critical angles where it would melt down?

I'm curious how you would make such a design that would be both using gravity yet tolerate being moved around.

I'd be more concerned about possible coolant loss and/or valve failures because of corrosion.

I suppose earthquakes and other disasters happen (and possibly tilt the reactor) however Earth is shaped?

Sure, you are right but i see HN needs the ⸮ ....
