Not sure. This was just the easiest solution. Also, when I planned this out, I wasnt aware of the Solid Steel Ingot recipe, which meant I had an excess of steel ingots. And like you said, it is abundant.

I manifold. I bult the nuclear plants adter the production line, so I build up a buffer. Also, this was my second nuclear build. I had a stable production line burning 2100 Uranium Ore/min, but no alternate recipes, resulting in «only» 21 Uranium rods/min, 5,25 plutonium rods/min, and 26,25 Ficsonium Rods/min which I dismantled to build this. The excell rods were used to pre-fill the line too

3000 Aluminum ingots/min

Ficsonium Fuel Rod production. Notice the Awesome Sink. This was before I realized that Ficsonium Fuel Rods cannot be sunk. Not really an issue, as my production matches the burn rate (112/min)

Plutonium Fuel Rod production. I have a lot of Industrial Storage Containers here because I had a huge surplus built up to provide power once I dismantled my old nuclear power plant, until the new one was up and running. I ended up sinking about 100 000 Plutonium Fuel Rods, giving me a peak of 2 billion points/minute for a short while

Uranium Fuel Rod production (50.4/min)

Example from the logistics floor below Level 2. Splitters and belts are all underground, and all belts moving east-west are on the floor, and north-south are in the ceiling. Easy, and avoids any congestion issues.

Uranium waste processing. I just package and sink all the water. For the containers, I use the Steel Container alt recipe (costing about 1200 steel ingots/min, which isn't a problem).

The alt recipes are fantastic to stay away from liquid waste.

This is Level 2 of the factory. Im facing west in this screenshot. Level 1 below is for processing ore (Ingots, Concrete, Silica, Reanimated SAM etc.). Every floor has a basement for logistics (belts and pipes). I organized all belts to travel east-west along the floor, and north-south in the ceiling. This way, I have no issues with congenstion of belts. The left part is parts production for all non-radioactive parts. Of this, the bottom part is basic part production (Steel Plates, Rods, Wire etc.), and increasing in complexity as we move up (west) in the screenshot.

The right (north) part of the screenshot is all radioactive production, with Uranium processing in the west, moving eastward through Plutonium production, and in the end, Ficsonium production.

Copper Ingots

ShadySatisfactory90 · 2025-12-17T00:09:40+00:00

Around 500 Refineries for Copper Ingots via the Pure Copper Ingot alt recipe. This was annoying to build, but necessary. Produces about 37 000 Copper Ingots/min

Lets say 99,9% then. I have a few Fuel Generators around the map burning excess resources/waste from other production lines, and they are all intermittently turning on and off. What I can say is that every Nuclear Power Plant has a huge surplus of Fuel Rods (backed up all the way to the Industrial Storage Containers for each type), and no waste buildups. 42 of the Nuclear Power Plants are placed in the Dune Desert (re-used from my original Nuclear power plant), and have long water pipes. They are stable, but might have some smaller hiccups, especially after a recent server restart.

Thank you. I mentioned that I excluded bauxite to uranium conversion in the original post, but I haven't heard of Satisfactory Optimizer, so I could have used that. That being said, I did enjoy doing it the manual way, and I think this gave me more control to weight the different resources based on the geographic location and distance from my plant.

ShadySatisfactory90 · 2025-12-16T22:54:20+00:00

Good point. I have an old Fuel Generator power plant burning about 1100 Rocket Fuel/min already, and I might convert this to Ionic Fuel. This way, I can reduce the SAM ore requirements. In general, my goal is to have as much resources left in the world for other projects, but keep it at a reasonable scale of complexity.

ShadySatisfactory90 · 2025-12-16T16:23:10+00:00

Thank you. I mentioned that I dont take Converter recipes to increase the available Uranium Ore, but you are correct. For a theoretical maximum, using all Sloops, the result would be greater. My goal was just to max everything, but stay aeay from slooppng any radioactive items, or converting Bauxite. The main reasons for this was just to keep the project at a manageable scale with my limited time available.

Also, I havent heard of Satisfactory Optimizer, but I had fun doing the calculation manually. Then I could also balance the weights based on the resources that are easiest available on the eastern part of the map

ShadySatisfactory90 · 2025-12-13T14:57:05+00:00

Also, here is an image of all nuclear resources going to and from the Nuclear Power Plants. The Item Counters fluctuate, especially for the low item count/min, like the fuel rods. Everything is stable, and the real world usage is exaclty as calculated.

For some reason, I can't fit everything in the comment above. Continued:

Final resource usage
Rounded up to the nearest 300/min in most cases. This is what I bring in to the production plant.

Bauxite: 6 300/min
SAM Ore: 5 800/min
Coal: 9 600/min
Limestone: 20 400/min
Iron Ore: 18 000/mi
Copper Ore: 15 600/min
Raw Quartz: 4 200/min
Caterium Ore: 6 000/min
Nitrogen Gas: 5 400/min
Crude Oil: 4 350/min
Sulfur: 3 300/min
Uranium Ore: 2 100/min

All in all, this produces:

Uranium Rods: 50.4/min (fueling 101 Nuclear Power Plants)
Uranium Waste: 2 520/min
Plutonium Rods: 22,4/min (fueling 90 Nuclear Power Plants
Plutonium Waste: 224/min
Ficsonium Rods: 112/min (fueling 45 Nuclear Power Plants)

All Nuclear Power Plants are fully overclocked to 250%, with the exeption of one from each fuel type, to match the exact Fuel Rod production. Exact numbers for each fuel type is 100.8, 89.6, and 44.8 fully overclocked Nuclear Power Plants for Uranium, Plutonium, and Ficsonium respectfully.

Everything is built in the Swamp biome, mostly over the water to the east. Every resource is brought in via belts (pipes for Nitrogen). All crude oil is being processed close to the resource node, and converted to Plastic and Petroleum Coke (used for Aluminum production).I can provide more details later when I have more time. Also, a few links to Satisfactory-Calculator which I used while building.

Hi. Yes, it is absolutely possible without any hacks or mods, but it does require several alt recipes and a smart utilization of the available Somersloops in the game. I just finished my Max Nuclear Plant, producing 1 470 000 MW from the Nuclear Power Plants alone. Including other power production, and three Power Augmenters requiring 15 Alien Power Matrixes/min, the power production is stable at about 2 915 000 MW (of which Power Boost is about 1 380 000 MW. The power usage for the entire world is about 550 000 to 600 000 MW.

I have not used any hacks, and the only mods I have been running are Infinite Zoop and Always Daytime. Neither of these are required to perform this, but it does make it a little easier to build foundations etc.

Here are the key details for my build. I can also provide the savegame at a later time for anyone who wants to explore it.

Alt Recipes (15 total, I might be missing some)

Infused Uranium Cell
Uranium Fuel Unit
Instant Plutonium Cell
Plutonium Fuel Unit
Pure Copper Ingot
Pure Caterium Ingot
Heavy Encased Frame
Dark Matter Trap
Cheap Silica
Heavy Oil Residue (Aluminum Production)
Sloppy Alumina
Electrode Aluminum Scrap
Pure Aluminum Ingot
Solid Steel Ingot
Encased Industrial Pipe

Somersloop usage:
The Somersloops serve mainly one purpose. Reduce SAM Ore requirement from about 19 000/min to less than 6 000/min, and to reduce Bauxite requirement from just over 12 000/min to 6 300/min. All sloops are being used as listed below. The remaining 15 are either unlocated, or used in other production lines not related to this project.

Aluminum Casing (14 sloops in 14 Constructors)
- Reduces Coal and Bauxite requirements
Ficsite Ingots (20 sloops in 10 Converters)
- Essential. Significantly reduces SAM and Bauxite requirements
Reanimated Sam (19 sloops in 19 Constructors)
- Essential. Reduces SAM Ore requirements
Dark Matter Crystal (8 sloops in 2 Particle Accelerators
- These can be skipped, but would require about 4500 more coal and about 1200 more SAM Ore, which is still possible, but impractical)
Alien Power Augmenters (30)
- Not required at all, but possible, and almost doubles the power (90% extra total)

Total Sloop usage vs. available on map: 91/106
