70 GW Nuclear Power Plant – No Waste using Raw Inputs Guide in Satisfactory

This guide explains how to build 70 GW of nuclear power where there is no lag term storage of nuclear waste and the only inputs are raw materials. This is quite a big build, it took me about 40 hours to figure out and build, although you can build a smaller version of it and expand as needed. We’ll break this into 3 sections, the first is building the nuclear power plants, the second is all the required raw materials and the last is the factory that produces the nuclear fuel rods and processes the waste from raw materials.

In this build you will need a lot of construction materials, see the following guide for how to bring them to construction sites without having to constantly go back to your home base to pick up more construction materials: https://auluftwaffles.com/2022/01/09/never-run-out-of-building-material-during-a-build-in-satisfactory/

Starting with the nuclear power plants, these require uranium fuel rods and about 300 water each and produce uranium waste. I picked a location above a big lake to put down all of the 28 required nuclear power plants. I build the water extractors on one level and the nuclear power plants on the level above that. I also grouped the nuclear power plants into 2 since that is a total water demand of 600 water per minute which is exactly the limit of Mk. 2 pipeline and can be fulfilled by 5 water extractors. I delivered the uranium fuel rods and pick up the uranium waste using a train transportation network that I also used to collect the raw materials.

Now moving onto sourcing the raw materials, you will need the following input materials with at the following rates per minute:

  • Copper ore: 780
  • Caterium ore: 540
  • Uranium: 500
  • Raw quartz: 135
  • Sulfur: 400
  • Nitrogen gas: 480
  • Limestone: 1620
  • Water: 8400 for power plants, 760 for production lines
  • Coal: 750
  • Iron ore: 690
  • Bauxite: 240

I looked for a location on the map for the production lines that had most of these raw materials available and also used a lot of power shards to boost the miner production rates to the maximum for a given raw material. For those that you can’t source locally you will need to ship it in using a transportation network. I used trains for my transportation network because they don’t require any fuel since they run on electricity and they also have high throughput since each terminal has 2 inputs and outputs. You will need to keep in mind that train terminal inputs and output cannot be driven at the maximum rate of your belts, especially if you are using both ports. This is because as the terminal loads/ unloads materials, no materials can be inserted or taken out of the terminal. For the Mk. 5 conveyor belts I usually assume that a single port can be driven at 720 materials per minute by drawing out both ports into an industrial storage container and then only using one of the output ports of the industrial storage and that that maximum rate if you are wanting to draw out raw materials from the terminal from both ports is 600 materials per minute per port.

Finally, moving onto the production lines producing the nuclear fuel rods and processing the waste. Below is a long list of the production steps that are required including which production building serves it, the input materials required and the output materials. This is for both the production of nuclear fuel rods and the processing of nuclear waste. There are some important notes to keep in mind:

  1. For the water production there is some output that certain stages need to sink. To keep things in balance you need to subtract that water output from the required input and be sure to only produce exactly the required amount of water by scaling down the output rate of some of the water extractors.
  2. Some pipelines and conveyor belts need to be doubled or tripled up, such as the limestone, since the material demand exceeds the 600 liquid capacity for Mk. 2 pipelines and Mk. 5 conveyor belts.
  3. Some production steps produce one of the inputs on the outputs, which is the case for sulphuric acid. In that case the net demand after subtracting the output needs to be produced. You will need to consider multiple input/ output iterations since the output is fed back into the input which then produces more output again.
  4. Some production lines will have to produce more than is strictly required because there isn’t an exact match between rates across recipes.
  5. Be sure to build the uranium waste to have over capacity so that you don’t end up with a lot of uranium waste in storage.
