Getting Started with Big Reactors

Before building a reactor you need to gather materials and craft the reactor parts.

• Mine Yellorium. Yellorium ore is the mod's core resource - it is both a crafting ingredient and the reactor fuel. Smelt/process it into ingots as needed.
• Craft the reactor blocks. The main parts you need are:
• Reactor Casing - the walls, floor, and ceiling of the reactor.
• Reactor Glass - optional see-through casing so you can watch the fuel rods inside.
• Reactor Controller - the "brain"; every reactor needs exactly one. This is where you open the control GUI.
• Fuel Rod - vertical columns inside the reactor that hold the fuel and where the reaction happens.
• Control Rod - sits on top of a fuel rod column to regulate the reaction.
• Access Port - lets you insert fuel and pull out waste (by hand, hopper, or pipes).
• Power Tap - outputs the generated power to your machines or storage.
