Here is a screenshot of my 200MW Nucular Power Plant. This is my first bots-based nuclear power plant, my previous ones used belts.
This factory consumes about 220MW, there is 40MW of solar generation but otherwise the Nuclear reactors provide all the power. Also visible is 40MW of backup power - an Oil Boiler and 12 Diesel Generators from KSPower. As I often do, I overbuild on Steam Turbines, having 20-50% extra steam turbines with storage tanks to better handle load spikes and make better use of reactors during lulls in electricity usage. A side effect of the 1000degrees steam is that storage tanks become much more effective too (tho I don't really use that). The volume of steam in the tank is fed into the circuit network and used as a condition to trigger the backup power, if the nuclear reactors are able to provide all required power to run the factory the tank will remain at 2500/2500. The oil burner comes on when the tank volume is less than 2300, it is a topping power plant, the Diesel Generators come on if the tank volume is less than 250 - that's for a real emergency when the power grid has been massively overtaxed for some time and/or the nuclear reactors are about to fail.
The setup appears to generate about as much nuclear fuel as it needs, it really should have more Uranium Enrichment but I wanted to focus more on the MOX fuel, hence the 13 Fast Breeders (they seem to work well, but don't even dent the depleted uranium stash, I have 20K of uranium and depleted uranium stashed away.
Finally I've killed myself several times with the Nuclear Rocket. Fighting trees. Even though I respect its lethality I do wish it'd deal ~6000 damage so it could kill Behemoth Biters.
