FBR Mega Station

Okay, so I think I found the issue that some people have had with fuel falling off from the enrichment reactor. It comes down to the core fuel balancing. The way it's setup in the BP, the central power generator reactor receives 1/3rd of the supply, and the other 4 receive 1/6th each. Until the central reactor maxes out its fuel supply, then it takes 8 from the supply, and the remaining 8 is split across the other 4 (so 2 per reactor). This means the other 2 power generators receive 10, the desalinator plant receives 10, and the enrichment reactor receives 10. The latter being the problem as it requires 16 to operate. So unless you use the core fuel factory to also saturate the entire pipe network, in addition to ensuring each reactor has 160 fuel to start, you will likely start imbalancing the fuel, and the enrichment reactor will eventually fall over, causing the whole plant to shut down.

The solution:

Take the balancer that splits the 2-ins to the 3 outs, and move it 2 spaces towards the power generation side (you need additional space so you can split the middle reactor with the desalinization reactor). Run a line from that straight back to the enrichment reactor, and remove the part where it splits to the desalinization plant. Then run another line back to connect to the desalinization and split that one into the middle reactor (this is tricky to do, and it's easier to fight with pipe snapping off). Don't forget to reconnect the 6x enrichment plants back into the moved balancer also.

Now your split with have 16 going to the enrichment reactor, then 16 being split to 8/8 for the desalinization plant and the middle reactor, and the other two power generation reactors split 16 as well. And all is perfectly balanced, as it should be. /thanos

Problem: Core fuel is distributed unevenly.

I did something similar to @schplat.

In the balancer where core fuel comes in, I connected two FBRs to each output. However, since it's an odd number, the third output was split and routed back to the balancer. (For this, I had to insert another balancer somewhere where there was space to ensure I had enough inputs and outputs.) This way, core fuel is distributed evenly among all. I haven't had any problems since.

I have tried so many of these FBR blueprints in the last month I am about to give up playing the game because the FBR doesn't work. I don't know if there was an update that broke them, there is an in game bug or if my files are corrupted. The fact remains that I can not produce power using Fast Breeder Reactors. I am unable to find any information on why this is not working. I started a new game and I am about to lay down stage 1 nuclear which is amazing considering how hard I worked to get it done but I am afraid when I get to stage 3 I am going to have the same problem. With a lack of an actual community in the game, I am pretty much on my own but I shall give this one a try for all the good it will do. This is my 5th attempt to get FBR online. It looks promising but I don't expect any miracles. Thanks in advance for the blueprint.

Any chance you can show an image of how to hook up the MOX processing?

@packtloss the MOX processing hooks up right next to the existing Nuclear Reprocessing Plants. Look to use the connector for the glass channel on the corner of the outermost Reprocessing Plant.

For those of you using this in U4, follow the instructions above from user schplat initially to get your core fuel balancing correct. Whilst it might be a challenge to visualise it, the wording is deliberate and achieves exactly what he said, although I personally moved the balancer 3 tiles rather than 2 to make it work. Very hard to get the pipes right.

I went one more step and took a stab at implementing a depleted uranium add-on since I'm sure a lot of you have used the smaller variant to get to this point (like me you have 20 max sized bins full).

To keep this short, you can utilise two of the power FBRs for this, I took the farthest two from the desalinators (nearest the processing plants), set at 1x enrichment, into a separate BFE t1 pipe loop that then feeds 2x enrichment plans (FBR -> BE and CF) and 8x chemical plants II (FBE + depleted uranium + salt). It's a perfect ratio, although to start up the process you'll need Calen's core fuel plant to run again, was about 2-3 in game minutes for me to fix the loop back to normal.

You can hook the blanket fuel from the chem plants straight back into the main line. You will need one more nuclear reprocessing facility to top up the extra core fuel usage (as running your FBRs on 1x is 50% more fuel use but same steam), but you can simply stack this processing plant next to the original three and jerry rig the provided pipes and belts. Just make sure you have enough salt ingress, I found that was the first stress point I encountered.

When you're eventually completely out of depleted uranium, simply change the two FBRs back to 0x.

Job done. Cheers from Aus.
