Corrosion depends on what the pipes are made of. There’s an alloy that seems to work pretty well, and worst case. There’s no water to react with. You can make your passive cooling tank however big it needs to be…to get absurd about it, if you had a tank with a perfectly flat and level floor a mile in diameter, you’d probably be ok. If you can’t make it work at a GW, go with smaller reactors. LFTR works fine for small reactors; it was designed for a nuclear airplane.
