This is a much larger version of the Small Reactor. The Large reactor is much more costly to build than a Small Reactor, but has a much larger power output, making it more efficient per construction material. Its Uranium efficiency is exactly equal to that of the Small Reactor. For more information on reactors in general as well as the mechanics, see Electricity#Reactors.
In order to use the reactor, the player must first acquire the needed fuel. First Uranium Ore must be mined and then processed with the Refinery into Uranium Ingots. These ingots is what powers both the small and large reactors. Power consumption is based on the amount of output the reactor is generating. The higher the output, the more uranium is used. It is far more economical to build one large reactor, than several smaller ones.
- Whenever you place uranium ingots into a container next to a conveyor block that is connected to the reactor ... the reactors automatically will evenly distribute the ingots between each other. If you wish to stop this, you have to turn off the conveyor option in the reactors control panel.
- If there is no power on the ship, you cannot transfer uranium into the reactor through containers or conveyors, it must be done directly. So always leave a spot open for manual input.
