I am not a particular railroad buff but there really is something about those old steam engines which is impressive as all get out.
I have read that nuclear powered ships are technically steam powered as the atomic material is used to create the steam.
You be right, just remember, there are two loops so irradiated water is never outside the shielding.
“nuclear powered ships are technically steam powered”
Anything nuclear powered is done so through steam.
the eternally hot core flashes water to steam to drive the turbines which drive the generators which drive the electricity.
