Choose a variant below. Closely related recipes, conditions or opening branches are collected here so you can compare them without moving between almost identical pages.
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 Nuclear heat and steam, 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.
Nuclear reactor
3.75 per minute · Buildings needed (rounded up): 16
| Source data | Batches | per minute |
|---|---|---|
| − Concrete | 500 | 1,875 |
| − Steel plate | 500 | 1,875 |
| − Advanced circuit | 500 | 1,875 |
| − Copper plate | 500 | 1,875 |
| + Nuclear reactor | 1 | 3.75 |
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
Nuclear reactor · 8 Seconds
Concrete × 500 + Steel plate × 500 + Advanced circuit × 500 + Copper plate × 500 → Nuclear reactor × 1
Station: Assembling machine 1 / Assembling machine 2 / Assembling machine 3
A worked example
Suppose you want 4 × Nuclear reactor. This recipe produces 1 per operation, so you need 4 operations. That produces 4 in total. The direct material list is Concrete × 2000, Steel plate × 2000, Advanced circuit × 2000, and Copper plate × 2000.
