Classics: Uranium
by hiisuuii
Classics: Uranium is a Fabric world generation mod that adds uranium ore, reactors, bombs and mutant mobs, the first mod of the Classics series.
What it does
Classics: Uranium is a from-scratch reimplementation of the first Uranium Mod, and it is the opening entry of the Classics series. Uranium Ore generates between heights -32 and 32 in the world, and mining it with a careful touch tool drops the ore itself. A cheaper route exists for making Uranium Ingots, which other irradiated items require.
Radiation plays a central role. Uranium Dust and Uranium Coal serve as fuel for the Nuclear Reactor, and Uranium Coal is a slightly better coal. To brew Potion Mutation, Mutagenic Flesh goes into an Awkward Potion; splashing that potion over ordinary Zombies and Skeletons yields Mutants and Radioactive Skeletons. The mod runs on Fabric 1.20.1 with Fabric API, and both the server and every player need it.
Key features
Uranium ore and ingots
Uranium Ore generates in the world, and smelting it yields Uranium Ingots used in later recipes.
Nuclear reactor and bombs
The Nuclear Reactor burns uranium fuel, and a Nuclear Bomb creates a massive explosion that spews Nuclear Waste.
Uranium tools and armor
Uranium tools and armor are slightly better than iron and have higher enchantability than gold.
Mutants and throwable bombs
Potion Mutation produces new mobs from regular Zombies and Skeletons, and packing TNT in a uranium shell makes a throwable bomb.

Use cases
Irradiated item crafting
Players who want the irradiated items in this mod craft Uranium Ingots through the cheaper route first, then move on to reactor fuel.
Mutant mob encounters
Server owners can add mutants and radioactive skeletons to the world by brewing Potion Mutation and splashing it on regular mobs.
Who it’s for: Players who want radiation-themed content in survival worlds, including the reactor, bombs and mutant mobs. Server owners who run a modded survival world can add it alongside other Classics content.
How it compares
RadiumTech is a Fabric mod that is open source under the MIT License and supports 1.19.3 – 1.20.1, so it covers a version range that overlaps this one. Natural Uranium is also a Fabric mod under the MIT License, but its only listed version is 1.21.10, so it does not overlap. Both share the client and server environment with this mod.

## The first in the Classics series! A complete rewrite of the original Uranium Mod by MinecraftForum user 'book'. In each case, either Uranium Dust or Uranium Coal can be used as fuel. Uranium Dust is enough to irradiate 1 item, and Uranium Coal can irradiate 3.
