For me a nuclear reactor is nothing more than a huge boiler. So it's only logically to make it a part of already existing steam setup.
The problem is of course that just adding another heating option is a little bit lame, so let's supersize things.
I would like to see another 'tier' of steam based power production which utilizes superheated steam at for example 400° to be used in steam turbines.
And what would be a nuclear power plant without those cooling towers? But this would need some type of used steam, still hot but not any more usable in steam engines or turbines, which i call here "old steam".
Changed resources: max water temperature is raised from 100° to 400°
New resource: "old steam"
New Buildings:
- Advanced boiler: heats water up to 400°, burns all kind of solid fuels and oil based fuels
- Nuclear Reactor: heats water up to 400°, burns radioactive fuels
- Steam turbine: uses 400° water to generate electric power, has option to generate "old steam" or higher pollution
- Cooling tower: uses "old steam" to generate water of maybe 80°
