Bigger Reactors Mod for Minecraft 1.20.1, 1.16.5
Official Continuation of Erogenous Beef's Big Reactors
About the Bigger Reactors mod
Bigger Reactors is the official continuation of the original Big Reactors mod, by Erogenous Beef.
Some things may not work the same as the original, and bugs are to be expected. If you find any, please report them on the Github Issues page, NOT here! Do read through the list first, though, as your bug may of already been reported.

You want power? We got power. Bigger Reactors is an energy generation mod based on the original by Erogenous Beef. Semi-inspired by real reactor designs, this mod allows for mix-n-match reactors to generate lots of power. Each block you place can change the overall performance of a reactor.
• Higher fuel efficiency? Yep.
• More power? Uh-huh.
• A giant reactor just to flex on your friends? Sure.
All you need to get started is some reactor casing, a power tap, access port, fuel & control rods, and terminal. Then just pipe/hopper in some Yellorium or Blutonium, flip the switch, and you're off!
Need more power? Just build some Bigger Reactors.
As of version 0.5.0, BiggerReactors has moved forward on Big Reactors' roadmap, see the wiki for the most up to date information on the mod.

How to install Bigger Reactors
With Millida Launcher
Install Millida Launcher
The launcher is free: download it at millida.net/launcher and sign in with any nickname.
Click “Install” on this page
The launcher opens and installs the mod for Minecraft 1.15.2–1.20.1 on Forge or NeoForge automatically.
Launch the game
A profile with it appears in the launcher: click “Play”.
Manually
Install Forge or NeoForge
The loader must match the game version of the mod file, for example Minecraft 1.20.1. After installing it, a separate profile appears in your launcher.
Download the file for your version
In the version list above, pick the file biggerreactors-1.20.1-0.6.0-beta.10.5.jar (1.2 MB) for your game version and loader.
Put it in the mods folder
The folder is inside .minecraft (Windows: %appdata%\.minecraft\mods). If it does not exist, create it.
Launch the loader profile
Open “Mods” in the main menu: Bigger Reactors should be in the list.
Minecraft 1.20.1 runs on Java 17: with a different Java version the game may close right after launch.
