Welcome. These are my four nuclear power plants, each one has a factory producing 3/min uranium fuel rods, 6 reactors at 250% and recycling 150/min uranium waste. One plant produces 37.500 MW, so it is 150.000 MW in total.

The plants can be run separately or all together as long as you make sure to fill the train stations with all needed resources. There are 10 train stations, each with four slots/cars. You need to bring in nearly every type of resource: Bauxite, Coal, Iron, Caterium, Oil, Nitrogen Gas, Sulfur, Limestone, Quartz and Copper.

Uranium is brought in by belt from the node nearby. I included this megaprint to have 4x300/min from one node: https://satisfactory-calculator.com/en/megaprints/index/details/id/1459/name/4C12T+-+Quad+Cores+Twelve+Threads+of+Uranium

1. Step 1: Connect the train stations to your rail network and bring in all the resources.
2. Step 2: Connect power lines and start the factory and the recycling.
3. Step 3: Start the fuel rod production and wait a few minutes for the reactors to start.

If you want to shutdown power production just stop the fuel rod production. the reactors will stop working after a few minutes. But make sure to keep the factory and the recycling running until all waste is processed.

No batteries / power storage included. I know i won't get a design price for this. So feel free to modify.

Enjoy.
