Reactor Controller (Big Reactors)

The Reactor Controller is one of the six basic parts needed to make a Big Reactor along side the Reactor Casing, the Yellorium Fuel Rods, the Control Rod, the Reactor Power Tap and the Reactor Access Port

In general Reactor Controller functions as the GUI interface blocks and shows if the Reactor multiblock is complete by turning Red. Should the Controller turn Green it signals that the Reactor is running.

Something important to note is that the Reactor in general has two cooling systems, passive and active with slight GUI changes. The difference between the two is the presence of the Reactor Coolant Port which allows water to be pumped in and Steam to be pumped out, typically into a Turbine
