Mekanism: More Fission
by Retrac860616
Mekanism: More Fission adds crafting recipes that make uranium ore and fluorite ore from common materials, so a Mekanism fission reactor can be fed without mining.
What it does
The mod adds recipes for uranium ore and fluorite ore. Uranium ore is crafted by surrounding one block of stone with eight pieces of cobblestone and gunpowder, and fluorite ore follows the same pattern with salt in place of gunpowder. The recipes let a player keep a fission reactor supplied with uranium and fluorite for the fissile fuel it needs.
Mekanism is required, and the mod is built on its machines. A server needs Mekanism Dependency installed alongside the mod; players need nothing extra. Automatic cobblestone generation is recommended as a companion, since the recipes consume a large amount of cobblestone. Files are published for NeoForge only, with 1.1.0 for 1.21.1 as the latest release, under All rights reserved. The mod is not open source.
Key features
Uranium ore recipe
Uranium ore can be crafted from a stone block surrounded by cobblestone and gunpowder, so the ore does not have to be found in the world.
Fluorite ore recipe
Fluorite ore is crafted the same way with salt, giving a second source of the fission inputs.
Constant fission supply
With these recipes, a reactor can run continuously instead of waiting on mined ore.
Automation-friendly inputs
The recipe materials are common, so cobblestone generators can feed the crafting chain automatically.
