The version and limits of the original source apply to every entry. Quantities and requirements belong to the named variant; do not add alternative recipes or opening lines together.
These options share a planning task. Their differences stay visible in the individual rows and calculators.
Using this reference
Choose a recipe for Uranium processing and fuel cells, then choose the machine that will run it. The per-minute rate uses the recorded output, recipe duration and machine speed. Batch quantities answer how many materials a fixed number of operations consumes; the rate column answers how fast one selected machine processes them.
Increase the target rate to see the number of whole machines needed. Rounding up leaves some nominal spare capacity. This is a direct production step, not a balanced factory: upstream supply, transport and temporary interruptions still need to support the stated rate.
Uranium-235
0.035 per minute · Buildings needed (rounded up): 1,715
| Source data | Batches | per minute |
|---|---|---|
| − Uranium ore | 10 | 50 |
| + Uranium-235 | 0.007 | 0.035 |
| + Uranium-238 | 0.993 | 4.965 |
Rates use the selected building at base speed. No modules, beacons, quality, power shortages or overclocking are simulated. Fractional outputs are expected averages, not guaranteed drops.
per minute = Batches × 60 × Production building / seconds per cycle
Uranium processing · 12 Seconds
Uranium ore × 10 → Uranium-235 × 0.007 + Uranium-238 × 0.993
Station: Centrifuge
Kovarex enrichment process · 60 Seconds
Uranium-235 × 40 + Uranium-238 × 5 → Uranium-235 × 41 + Uranium-238 × 2
Station: Centrifuge
A worked example
Suppose you want 1.02 × Uranium-235. This recipe produces 0.01 per operation, so you need 146 operations. That produces 1.02 in total, leaving 0 extra. The direct material list is Uranium ore × 1460.

Nuclear fuel reprocessing · 60 Seconds
Depleted uranium fuel cell × 5 → Uranium-238 × 3
Station: Centrifuge
Kovarex enrichment process · 60 Seconds
Uranium-235 × 40 + Uranium-238 × 5 → Uranium-235 × 41 + Uranium-238 × 2
Station: Centrifuge
A worked example
Suppose you want 3.98 × Uranium-238. This recipe produces 0.99 per operation, so you need 5 operations. That produces 4.97 in total, leaving 0.99 extra. The direct material list is Uranium ore × 50.

30 per minute · Buildings needed (rounded up): 2
| Source data | Batches | per minute |
|---|---|---|
| − Iron plate | 10 | 30 |
| − Uranium-235 | 1 | 3 |
| − Uranium-238 | 19 | 57 |
| + Uranium fuel cell | 10 | 30 |

per minute = Batches × 60 × Production building / seconds per cycle
Uranium fuel cell · 10 Seconds
Iron plate × 10 + Uranium-235 × 1 + Uranium-238 × 19 → Uranium fuel cell × 10
Station: Assembling machine 1 / Assembling machine 2 / Assembling machine 3
A worked example
Suppose you want 31 × Uranium fuel cell. This recipe produces 10 per operation, so you need 4 operations. That produces 40 in total, leaving 9 extra. The direct material list is Iron plate × 40, Uranium-235 × 4, and Uranium-238 × 76.
