Extreme Reactors is a Java mod for NeoForge and Forge that brings back Big Reactors, Erogenous Beef's 1.7.10 mod, rewritten by ZeroNoRyouki. You assemble multiblock reactors and turbines that turn fuel and steam into energy, and the files install on both sides of a multiplayer world. It needs the ZeroCore 2 library to run.
Loaders and versions
- NeoForge: Minecraft 1.20.1 to 1.21.4. The newest build requires ZeroCore 2, optionally Patchouli; some builds for 1.20.6 to 1.21.4 need no dependencies.
- Forge: Minecraft 1.12.2 to 1.20.1. The newest build requires ZeroCore 2, optionally Patchouli.
What you build
Reactors and turbines are large multiblock machines made from casing, glass, a controller and a set of ports. Reactors harness the power of the atom, and turbines turn steam into energy. Output leaves through Forge Energy Power Taps, so most modded machines can draw from it. The mod is built so other power systems can be added later.
Fuels and late-game coils
- Fluid fuels let you feed reactors through a Fuel Injection Port set to inlet mode, with no material loss. Fluid waste leaves through a port set to outlet mode.
- The Fluidizer is a multiblock that converts solid or fluid fuels into fluid fuel. Mixing two fuels usually gives a better one, and Verderium is the top-tier fuel.
- Ludicrite, Ridiculite and Inanite turbine coils are the late-game option. A full coil in a Reinforced Turbine should give around 45K, 75K and 115K FE/t respectively.
- Pack authors can tune fuel values and new coils with the /er command (operator level 2 or higher).
Setup notes
Add the matching ZeroCore 2 file to your mods folder next to the mod itself. The in-game manual needs Patchouli. If you are new to loaders, the Forge and NeoForge guide covers the setup.
An incomplete multiblock no longer shouts at you. On 1.20.6 and later you must sneak to see its error message.

Questions about Extreme Reactors.
4 questions
Does Extreme Reactors work on Fabric?
Not yet. Builds exist only for NeoForge and Forge. The creator says a Fabric port is being worked on but gives no release date, so Fabric players need a different reactor mod or a loader switch for now.
What do I need to install with Extreme Reactors?
ZeroCore 2 is required. Patchouli is optional and adds the in-game manual. Some NeoForge files for 1.20.6 to 1.21.4 need no dependencies.
How much power can an Extreme Reactors turbine make?
With the late-game coils, a full coil in a Reinforced Turbine should give around 45K FE/t for Ludicrite, 75K for Ridiculite and 115K for Inanite. Output uses Forge Energy, so most modded machines can connect through a Power Tap.
Is Extreme Reactors the same as Big Reactors?
It is a port and rewrite of Big Reactors, the 1.7.10 mod by Erogenous Beef. The name changed to follow CurseForge deployment rules. The core idea of multiblock reactors and turbines remains, with newer features such as fluid fuels and the Fluidizer.
