Reactor Controller (Big Reactors)

The Reactor Controller is a block added by Big Reactors. It is one of the six basic parts needed to make a Big Reactor along with the Reactor Casing, the Yellorium Fuel Rods, the Control Rod, the Reactor Power Tap, and the Reactor Access Port.

The Reactor Controller functions as the GUI interface block and shows if the Reactor multiblock is complete by turning Red. When the Reactor is running it will turn green..
