Coal and nuclear have equivalent steam sides. Well, nuclear often has even more complexity with separate loops with heat exchangers to minimize contact between the reactor water and rest of the plant.

CCGT turbines are a bit different in that they have turbine first, and then the same steam boiler to turbine setup.

That is why I ask. All generation from mechanical sources needs generators, they need control circuitry. Steam plants need boilers, cooling towers and what not.

Just wanted to point out that singularly focusing on "hurr durr renewables need to dig stuff out from the ground and not made using pixie-dust" is quite the irrelevant take since the entire energy generation industry shares so much complexity, no matter the source of energy.
