Big Reactors is officially retired. Thank you all for downloading and enjoying the mod! If you're looking for a version of Big Reactors for newer versions of Minecraft, we endorse Bigger Reactors as our official successor -- go check it out!

Big Reactors emphasizes the construction of large machines out of multiple blocks, or “parts”. It's designed to complement less-realistic mods such as Thermal Expansion, Applied Energistics 2, and Minefactory Reloaded. These mods all offer fun ways to manipulate and “industrialize” your Minecraft world, and rely on a shared power framework.

My core design goal is to provide fun, engaging power systems that are “inspired by” real ones, while maintaining a light-hearted “video game” feel. It should be fun to set up your reactor, fun to modify it, and fun to figure out how to make it work the way you want. More power? Less fuel consumption? A highly-automated sprawling mega-reactor? It's up to you.

I also wanted the mod to move away from big, heavy-weight UI systems. A reactor shouldn't be a series of toggles on a menu, or slots in an inventory.

A reactor should be a giant, humming machine which you build piece-by-piece — and every piece you add should change how the reactor works!

The result? Big Reactors.
