Burns Uranium Fuel Rods for the most power of any plant. Needs Fission Physics. Stops when the rods run out.
Support a larger grid with crafted Fuel Rods. Secure a component supply before depending on it; a powerful generator without fuel cannot keep industry running.
To establish this building, you need 🏛️ Main Building level 1; research: Fission Physics.
For later upgrades, the Main Building must also reach the target level. The level table shows the resource and time investment before bonuses.
The building definition has no direct structural or active power upkeep. Check the powered extractors, crafting and recruitment that support its use when planning the wider grid.
📸 Screenshot wanted: the Reactor detail panel in a colony (level, upgrade cost and its main controls visible). If the building has a Race name, one shot per Race is ideal.
