Uranium Processing Plant for 50 reactors

Post by Raphaello »

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.

Image

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:
Blueprint
Here are the recipes as of 0.15.10:

Code: Select all

Uranium Processing          Kovarex Enrichment          Fuel Cell recipe    
Time        10              Time        50              U235 In         1
Ore In      10              U238 In     5               U238 In         19
U235 Out    0,70%           U235 Out    1               FuelCell Out    10
U238 Out    99,30%          U238 Out    2               U235/U238 Ratio 5,26%
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:

Code: Select all

Uranium Processing      Kovarex Enrichment
Cycles      1000        Cycles      200         
Time        10000       Time        10000           
Ore In      10000       U238 In     1000            
U235 Out    7           U235 Out    200        U235 Total  207
U238 Out    993         U238 Out    400        U238 Total  393
                                               Ratio       52,67%
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:

Code: Select all

Uranium Processing      Kovarex Enrichment
Centrifuges 5           Centrifuges 1    
Ore In     10000        U238 In     1000            
U235 Out    35          U235 Out    200        U235 Total  235
U238 Out    4965        U238 Out    400        U238 Total  4365
                                               Ratio       5,38%
However, for a better looking design, I'd prefer 4 ore processing centrifuges, so let's optimize the setup with modules and beacons:

Code: Select all

Uranium Processing          Kovarex Enrichment
Centrifuges     4           Centrifuges 1           
Speed           120%        Speed       120%            
Productivity    120%        U238 In     1200            
U235 Out        40,32       U235 Out    240     U235 Total  280,32
U238 Out        5719,68     U238 Out    480     U238 Total  4999,68
                                                Ratio       5,61%
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?

Code: Select all

Fuel Cell usage                         
Number of reactors      50                      
Fuel cell burn time     200                     
Fuel cells needed       2500                    
                            
U235 needed             250                     
U238 needed             4750  
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 :shock:

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

Nice ... however productivity modules doesnt work any more!

Also "Fuel cell burn time 120 " is wrong. Its 200s.

What do you mean? They certainly work in ore processing - I tested it and got 6 U238 from 50 ore. Productivity modules don't work in enrichment of course so I don't use them there.

Ups ... your right ... my fault!
Doesnt know that its working there.
