Uranium Processing Plant for 50 reactors
Posted: Sun May 14, 2017 8:20 pm
How big does the uranium processing need to be? The setup below is all you need to power up to 50 reactors. It also automatically reprocesses spent fuel and increases amount of U235 from mining and ore processing.
Enrichment process needs to be started manually by putting 40 U235 into one of steel chest on the left side (next to enrichment centrifuge).
Here's the blueprint if you want to try:
If we only produce fuel cells (oh, sweet nukes!) then we need 1 U235 for 19 U238 - a ratio of 5,26%.
So, in 10000 seconds we can expect the following productionif we run 1 centrifuge for ore processing and 1 for enrichment:
In this time ore processing will give me 7 U235 and 993 U238. This is clearly not a good ratio so I run 1 enrichment centrifuge which consumes 1000-400=600 of U238 to create 200 U238. The whole setup produces 207 U235 and 393 U238. Ratio is way overboard on 52,67%.
We need 5 ore processing centrifuges to come to (almost) perfect ratio:
However, for a better looking design, I'd prefer 4 ore processing centrifuges, so let's optimize the setup with modules and beacons:
The end ratio is a bit higher than ideal but it can be lowered by removing (or further increased by upgrading) speed module in enrichment centrifuge. You'll want lower ratio when using a lot of uranium ammo, higher is better for nuke fans.
So, how many reactors can we run from this setup?
If we have 50 reactors burning constantly then we need 2500 cells for 10000 seconds (assuming continous operation). To produce those cells 250 U235 and 4750 U238 is needed 
So (unless there's an error in my math) we can run more than 50 reactors continuously from this compact setup
edit: corrected cell burn time to 200
