This is the guide to advanced nuclear power where we will be building a full cycle Nuclear setup up to Ficsonium. It produces a total of 56250MW of power with zero waste! It is somewhat inspired by a No Nuclear Waste - Nuclear Power Super-Efficient Build Layout[www.satisfactorytips.com] guide posted by a youtuber TotalXclipse, that I strongly recommend to check out, especially if this is your first attempt at going Nuclear in Satisfactory as it is much more beginner friendly. In that guide the production chain ends up with us creating a Plutonium Fuel Rod and then dumping it into the Sink, which made me a bit sad, so I decided – hey, why don’t we try to put this juicy power rod to use and see what happens. And here is the result.

Unlike other types of power generators in Satisfactory Nuclear Power Plants have one downside – as they burn fuel they also create Waste as a by-product and because waste cannot be sent to the Sink or even deleted from our inventory, we need to find a way to deal with it somehow.

• Our 1st option is to create a huge storage in the middle of nowhere, connect outputs of our NPPs to it and just keep dumping our waste there. I’m not judging but if this is your way to deal with the wastes we simply cant be friends.
  
• Our 2nd option is recycling, meaning that we put our wastes through a number of transformations by the end of which we receive a usable item (Plutonium Fuel Rod) that we can get rid of by sending it to the sink.
  
• And the 3rd option is to use Plutonium Fuel Rod that we got from the previous option in another set of NPPs. Which in turn creates Plutonium Waste with another, much more complicated recycling process. Our final prize will be Ficsonium Fuel Rod, that can also be used to power NPPs but this time with no waste so our mission will be complete. Needless to say this is exactly what we will be doing here.

Those people who just switched from coal/fuel and are new to Nuclear Power may have a question (I definitely had it before I dived deeper into nuclear production chain) – “Cant we just design Nuclear Power that uses just Plutonium Fuel Rods and completely ignore Uranium, which are twice as less effective? It worked for fuel generators when I discovered Rocket fuel, so isn’t it something similar here?” The answer is – No you cant. Uranium Waste is the KEY component to creating Plutonium fuel and cant be replaced with anything else. Same goes for Ficsonium Fuel – you absolutely need Plutonium Waste to create it. So the simplified production chain would look smth like this: Uranium Fuel Rod -> Uranium Waste -> Plutonium Fuel Rod -> Plutonium Waste -> Ficsonium -> Ficsonium Fuel Rod -> Profit.

• This guide only covers the nuclear part of the project assuming that you are capable to set up the production of all the basic parts like Concrete or Iron plates on your own.
  
• To have access to all required production parts and buildings you need to have ALL of your Tier 9 milestones unlocked (except the Blueprints Mk.3)
  
• The production uses a lot of alternate recipes (I think I actually use all the alternate recipes that deal with Nuclear parts) so before you start make sure that you have all of them unlocked. There is a complete list in the requirements part of the guide.
  
• It will take a lot of time to get it all up and running so clean up your schedule. I think it took me 3 or 4 days to plan, build and tweak the entire thing but you should probably do it faster since we already have (almost) everything planned and calculated.
  
• We also need to find a suitable location to deploy our project. And since our NPPs alone consume over 5k water/min, the best way would be to do it right on top of some large body of water like we have near the northern border of the map.

A 70x40 grid (that is 14k Concrete and 5.6k of Iron plates). You can probably squeeze the whole thing into a smaller area but I used a more broad layout to give a better visual understanding of the setup.
Also 25xPower Shards.

Now lets get to the main production part of this guide. Here is the birdview of what the whole project will look like after we are done:

To make things a bit more organized I split it into 2 logical parts. Lets call them Nuclear Cycle - 1 and Nuclear Cycle – 2.

First lets construct 2 Manufacturers (M1 and M2 on the screenshot) that will be responsible for our Uranium Fuel Rod production.
M1 is set to 150% speed and produces 30xEncased Uranium Cells using Infused Uranium Cell alternate recipe. It uses the following raw inputs:

• 37.5 Uranium
  
• 22.5 Silica
  
• 37.5 Sulfur
  
• 112.5 Quickwire

The Encased Uranium Cells are then sent to M2 Manufacturer.
M2 is also set to 150% speed and produces 0.9xUranium Fuel Rods using Uranium Fuel Unit alternate recipe. It uses the following input:

• 30 Encased Uranium Cells (from M1)
  
• 3 Electromagnetic Control Rod
  
• 0.9 Crystal Oscillators
  
• 3 Rotors

The amount of produced Uranium Fuel Rods is exactly what we need to constantly supply our first set of 3 Nuclear Power Plants (NPP1), each set to 150% speed. We connect M2 to NPP1 using a single splitter so we have a balanced supply to each Power Plant.
Now let us also set up Water Extractors. Each Power Plant requires 360 water per minute so we are simply using 3 Water Extractor each set to 100% (3x120) for every Power Plant. We will need to tweak the water supply of the Power Plant closest to B1 Blender, I’ll cover that in the next step.

Now that our first set of Power Plants (NPP1) is up and running they also start producing 45 Uranium Waste per minute (15 each) so lets deal with it. We send them all to B1 Blender. It is set to 180% speed and produces 180xNon-Fissile Uranium using Fertile Uranium alternate recipe. It uses the following input :

• 45 Uranium
  
• 45 Uranium Waste (from NPP1)
  
• 27 Nitric Acid
  
• 45 Sulfuric Acid

(Both Nitric and Sulfuric Acid pipes are hidden inside the foundation so aren’t visible on the big picture, but trust me they are there).
Now that we set up our Blender we notice that besides Non-Fissile Uranium it also produces 72 water per minute as a by-product. The smartest way to deal with it will be to simply connect the water output of our Blender to the pipe that supplies the nearest Power Plant with water. We also need to lower the production of Water Extractors so we set all 3 of them to 80%. What we now have is 3x96 water per minute from Extractors plus 72 water per minute from the Blender, which equals to exactly 360 water per minute this Power Plant needs to normally function. With this out of the way lets move to our next step.

We now send the Non-Fissile Uranium we produced in the Blender to our 1st set of 3 Particle Accelerators PA1.
PA1 Particle Accelerator each set to 80% and produce a total of 24xEncased Plutonium Cell (8 each) using yet another alternate recipe - Instant Plutonium Cell. They use the following input:

• 180 Non-Fissile Uranium (60 each) from B1
  
• 24 Aluminum Casings (8 each)

We now merge outputs of all 3 Particle Accelerators into one belt which goes to a set of two Assemblers A1.
A1 Assemblers both set to 120% speed and produce a total of 1.2xPlutonium Fuel Rod (0.6 each) using Plutonium Fuel Unit alternate recipe. They use the following input:

• 24 Encased Plutonium Cells (12 each) from PA1
  
• 1.2 Pressure Conversion Cubes (0.6 each)

Now that production of Plutonium Fuel Rods is fully set up we consider our Nuclear Cycle – 1 complete. In the next part we will set up a production line to deal with Plutonium Waste and in the end get our final prize - Ficsonium Fuel Rods. Lets go.

The amount of Plutonium Fuel Rods produced by A1 Assemblers is exactly what we need to constantly supply our second set of 6 Nuclear Power Plants (NPP2), each set to 200% speed. To assure a balanced supply of fuel rods to every Power Plant in NPP2 segment we connect the output of the left Assembler to 3 NPPs in the upper row using a single splitter and in the same way the right Assembler is connected to the lower row of 3 NPPs also using a single splitter.
Each of these Power Plants also needs 480 water per minute so we also need to construct 4x100% Water Extractors for every plant.

Now the time comes to deal with Plutonium Waste that our second set of Power Plants (NPP2) started producing. The production cycle is slightly more complicated than the Uranium one so pay attention. First we need to set up the production of some parts that will be needed in the process.

Lets start with placing 3 Particle Accelerators (PA3) in the lower left corner of the grid. They will be producing a total of 1.2xNuclear Pasta (0.4 each) so set all 3 of them to 80% speed. They use the following raw input:

• 240 Copper Powder (80 each)
  
• 1.2 Pressure Conversion Cubes (0.4 each)

Next place a Manufacturer (M3) 5-6 tiles above Particle Accelerators from the previous step.
We then merge all 3 outputs of PA3 into one belt and connect it to one of the M3 inputs. This Manufacturer will be producing 12xSingularity Cells per minute and has the following input:

• 1.2 Nuclear Pasta (from PA3)
  
• 24 Dark Crystals (from PA4)
  
• 120 Iron Plates
  
• 240 Concrete

Now we need to setup the production of 24xDark Crystals for the M3 Manufacturer from the previous step. To do so place 2 Particle Accelerators (PA4) on the left side of M3. The first Particle Accelerator will be producing 24xDiamonds from either Coal using basic recipe, or from Crude Oil using Oil-based diamonds alternate recipe. In my setup I use oil variant because there was a free Crude Oil node nearby and also it is slight more power efficient, but you are totally free to use any of the 6 recipes you like to make those Diamonds.
We now send these Diamonds to the second Particle Accelerator where they will be turned into 24xDark Matter Crystals using the basic recipe and is working at 80% speed. The second component we need in this recipe – Dark Matter Residue will be coming via a pipe from a set of Quantum Encoders (QE) but we will deal with this later.
Now that we have everything needed to produce Singularity Cells lets move to the next part.

Place 3 Convertors (C1) on the right side of M3 Manufacturer. They will be producing 240xDark Matter Residue (80 each) so set them all to 80% speed. Connect them to the outside supply of Reanimated SAM – we need a total of 120xReanimated SAM per minute (40 each).

With that done we should now have all the required parts to process Plutonium Waste that the second set of Power Plants (NPP2) is creating. Place another Particle Accelerator (PA2) ~3 tiles above the C1 Convertors from the previous step. Connect the first input to M3 Manufacturer, connect the pipe input to the merged pipe of C1 Convertors and finally connect the second input to the merged conveyor belt of all 6 Nuclear Power Plants from NPP2. Set the production to Ficsonium and speed to 120%. This Particle Accelerator will be producing 12xFicsonium and should have the following input:

• 12 Plutonium Waste (from NPP2)
  
• 12 Singularity Cells (from M3)
  
• 240 Dark Matter Residue (from C1)

Now before we get to the final step of creating Ficsonium Fuel Rods a couple more things need to be done.

First lets set up a small factory that will be producing Ficsite Trigons in the upper left corner of the grid (F.Tri).
Place 4 Convertors so that their outputs are facing each other and set them to the production of Ficsite Ingot (Aluminum). We need a total of 80 ingots per minute so just manually set their production rate to 20 Ficsite Ingots per minute for every Convertor. They will need the following input:

• 320 Aluminum Ingots (80 each)
  
• 160 Reanimated SAM (40 each)

Next place 8 Constructors to the right side and set their production to Ficsite Trigons at 100% speed so that they will be producing a total of 240xFicsite Trigons per second (30 each). Connect them to the supply of Ficsite Ingots coming out of the Convertors and merge the output of Constructors themselves into one belt. We will need those trigons in the final step of our production chain in Quantum Encoders (QE).

Lastly place another Convertor (C2) on the left side of PA2. It will be producing Excited Photonic Matter out of thin air. We need a total of 120 Excited Photonic Matter per minute so set the speed of this Convertor to 60%.

Now finally we have everything to create Ficsonium Fuel Rods.
(keep in mind that image below is rotated by 180 degrees compared to the big picture so dont get confused)
Place 3 Quantum Encoders (QE) above PA2 and to the right of our ficsonium trigon factory (F.Tri). Set them to 80% speed each creating Ficsonium Fuel Rods. Lets examine their inputs more closely. First the pipe inputs should all be connected to the C2 Convertor which produces Excited Photonic Matter. Next connect the first belt inputs to PA2 producing Ficsonium. Connect the second belt inputs to the supply of Ficsite Trigons from the Ficsite trigon factory (F.Tri) on the left side. And lastly connect the 3rd belt inputs to supply of Electromagnetic Control Rods from outside. Here is the input summary:

• 120 Excited Photonic Matter (40 each) (from C2))
  
• 12 Ficsonium (4 each) (from PA2)
  
• 240 Ficsite Trigons (80 each) (from F.Tri)
  
• 12 Electromagnetic Control Rods

Before we send our Ficsonium Fuel Rods to the final set of NPPs lets deal with Dark Matter Residue that our Encoders also create. Merge all 3 of the Dark Matter Residue pipes into one and connect it to the Particle Accelerator (PA4) producing Dark Crystals. Now here is a tricky part – if you closely examine our production chain you will notice that we have a loop ->PA4->M3->PA2->QE-> where every production unit depends on the part from the previous one which means that none of them will start working until we feed it from the outside first. Basically you need to manually dump like a 100 Dark Crystals from your inventory into the M3 Manufacturer so it starts producing Singularity Cells. Once we jumpstart this part like that our Encoders will be constantly producing a total of 120xDark Matter Residue and then sending it back to PA4 so no further interference will be needed.

Now lets take the final step in our journey and put those Ficsonium Fuel Rods to use.
(this image is also rotated by 180 degees)
We are producing 6 Ficsonium Fuel Rods per minute which is the exact amount needed to fuel 6 Nuclear Power Plants or in our case 3 Nuclear Power Plants set to 200% speed. As Power Plants from NPP3 are using the same parameters as in NPP2 we can simply copy one row of Power Plants along with the Water Extractors from NPP2 and place them in the upper right corner of the left side of the grid. Connect each of them to the supply of Ficsonium Fuel Rods coming from Quantum Encoders (QE) and since Ficsonium doesn’t produce any waste this is the end of the line and we are finally done!
