Uranium Big Reactor: Uranium Fuel & Cooling for Extreme Reactors
For players running large-scale multiblock reactors in Minecraft, the Extreme Reactors mod (formerly Big Reactors) has long been a staple for high-output power generation. However, the default fuel options can feel limiting, especially when your base also runs IndustrialCraft 2. Uranium Big Reactor: Uranium Fuel & Cooling for Extreme Reactors solves this by bridging the gap between these two major tech mods, letting you feed your reactor with IC2's enriched uranium and advanced coolants without writing a single script.
What This Addon Adds to Your Reactor Setup
This lightweight addon registers a new fuel source for reactor rods. Instead of relying solely on standard yellorium or basic uranium ingots, you can now power your Extreme Reactors turbine with several alternative inputs. The mod accepts enriched uranium nuclear fuel from IndustrialCraft 2, any item tagged as "uraniumFuel" in the Ore Dictionary, and any liquid named "uraniumfuel" that you pump into the reactor's fuel port. This flexibility is a major win for modpack builders who want a unified nuclear fuel cycle across multiple mods.
Fuel Flexibility and Visual Feedback
When you load the reactor with uranium-based fuel, the Reactor Fuel Rods display a bright green liquid color. This is not just a cosmetic change; it provides immediate visual confirmation that the reactor is running on the new fuel type. As the uranium depletes, the rods produce cyanite as a byproduct, which you can reprocess into useful materials or integrate into other tech chains. Future versions of the mod are planned to swap cyanite for plutonium, adding even more depth to the nuclear cycle.
Advanced Cooling Options
Managing reactor temperature is critical to preventing meltdowns and maintaining efficiency. Uranium Big Reactor: Uranium Fuel & Cooling for Extreme Reactors expands the list of acceptable coolant fluids, allowing you to use IC2 Coolant and liquid UU-Matter. Both fluids are highly effective at heat dissipation and are commonly available in bases that already run IndustrialCraft 2 machinery. By connecting your existing coolant tanks to the reactor ports, you avoid building a separate cooling infrastructure just for Extreme Reactors.
Why This Matters for Your Tech Progression
For players who combine IC2 and Extreme Reactors in the same world, this addon removes artificial barriers between the two mods. The uranium processing chain becomes fully integrated: mine ore, process it through IC2, and feed the enriched product directly into your Big Reactor. This saves space, reduces resource duplication, and makes your power grid more coherent. The mod also supports any third-party mod that registers items or fluids with the appropriate ore dictionary tags, so it works well in custom modpacks.
How to Install and Compatibility
Uranium Big Reactor: Uranium Fuel & Cooling for Extreme Reactors is a simple addon with minimal dependencies. You will need Extreme Reactors installed as the base mod, and IndustrialCraft 2 is optional but recommended if you want to use the enriched uranium and special coolants. The mod supports Minecraft versions commonly used with these tech mods, and it works with both Forge and NeoForge loaders, depending on your Minecraft version. Always check the mod's file page for the exact loader and game version compatibility before downloading.
To download Uranium Big Reactor: Uranium Fuel & Cooling for Extreme Reactors, simply grab the jar file from a trusted mod repository and place it in your mods folder. If you prefer a more automated approach, many third-party launchers allow you to install the mod directly from their catalog, which automatically checks version compatibility with your existing mods. For manual installation, the process is straightforward: download the file, drop it into the mods directory, and restart your game. The mod is open source under the MIT license, so you can also review the code or contribute to its development.
Final Thoughts on This Reactor Addon
Uranium Big Reactor: Uranium Fuel & Cooling for Extreme Reactors for Minecraft is a focused, practical addition for players who want deeper integration between their tech mods. It does not add cumbersome mechanics or bloat your pack; instead, it delivers meaningful options for fuel and cooling. The visual feedback from the green fuel rods and the byproduct generation make the reactor process more engaging, while the open license ensures the mod will continue to evolve. If you are building a large-scale energy complex and want a seamless connection between IC2 and Extreme Reactors, this addon is worth adding to your stable modpack.
