Uranium fuel cell — Factorio Production Calculator
Uranium fuel cell is crafted in the assembling machine in 10 seconds, producing 10 per craft from 10 × Iron plate, 1 × Uranium 235, 19 × Uranium-238. At 60 per minute you need 2 assembling machines, and the chain behind it draws on 3 raw resources: depleted uranium fuel cell, iron ore, uranium 235.
Production chain for 60 Uranium fuel cell / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Uranium-238 | 114 | 38 | Centrifuge |
| Uranium fuel cell | 60 | 2 | Assembling machine |
| Iron plate | 60 | 3.2 | Furnace |
Raw materials
| Resource | Per minute |
|---|---|
| Depleted uranium fuel cell | 190 |
| Iron ore | 60 |
| Uranium 235 | 6 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Uranium fuel cell recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 10 s | 10 | Iron plate × 10, Uranium 235 × 1, Uranium-238 × 19 |
What the whole chain needs
60 uranium fuel cells per minute pulls in 2 intermediate products, and the whole tree comes to 43 machines across 3 machine types, fed by 3 raw resources. The table above already sums demand across every branch — if copper cable is used by two recipes, you see the total, not one of them.
Belt check: the busiest input here moves 190 per minute, which is 0.21 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.
What uses uranium fuel cell
1 base-game recipe consumes uranium fuel cell, sorted by how much each one takes:
- Portable fission reactor — 4 per craft
What uranium fuel cell is made from
- Iron plate — 10 per craft
- Uranium-238 — 19 per craft
FAQ
How many assembling machines do I need for 60 uranium fuel cells per minute?
2 assembling machines. One at standard speed produces 30 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does uranium fuel cell take?
At 60/min the chain consumes 190 depleted uranium fuel cell per minute, 60 iron ore per minute, 6 uranium 235 per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is uranium fuel cell needed for science packs?
Not directly. It feeds Portable fission reactor, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
