Big Reactors — FAQ

Tips and FAQ

My multiblock will not form. The outer shell must be completely sealed with reactor blocks (every face, edge, and corner), there must be exactly one Controller, and fuel rods must be full-height columns. Any gap or extra controller stops it forming.

The reactor is on but makes no power. Make sure it actually has fuel in the tank, that it is toggled on, and that you are pulling power from a Power Tap (not the casing). An empty fuel tank means no reaction.

How do I get more power? Build a bigger reactor with more fuel-rod columns, tune the control rods for output, and for large builds switch to the steam + Reactor Turbine setup.

What is Yellorium / Cyanite? Yellorium is the reactor fuel you mine and insert; Cyanite is the waste produced as fuel is consumed - pull it out through the Access Port.

Does Big Reactors need anything else installed? Yes - it requires the ZeroCore2 library, which provides the multiblock and GUI systems it is built on. Install ZeroCore2 alongside Big Reactors.
