Thorium Reactors
Thorium Reactors adds a Forge and NeoForge power-generation system built around a thorium reactor that players construct and fuel themselves.
What it does
Players explore underground depths to find up to 11 ores and minerals, then dig deep into the ground for resources used in the mod's recipes and machines. Once enough material is gathered, a player builds a reactor, fuels it with thorium, and monitors it through a large control interface that shows its status, helping keep output stable and efficient.
The reactor produces steam, which feeds turbines to generate continuous power. The mod also includes machines, tools and advancements that mark progress through the content, and it integrates with other mods, so its ores and machines can appear alongside them. Thorium Reactors runs on client and server, so the server and every player need it. It is published for Forge and NeoForge in two game versions, 1.19.2 and 1.20.1, and the MIT License covers the code, which is open source. Its optional dependencies are CC: Tweaked, Jade and The One Probe.
Key features
Underground ore discovery
Up to 11 ores and minerals are spread through the underground, giving players a reason to dig deeper.
Thorium reactor construction
Players assemble their own reactor from blocks and fuel it with thorium to start the generation cycle.
Reactor control interface
A large monitoring screen tracks the whole reactor so players can adjust settings and watch output.
Steam-driven turbines
Steam produced by the reactor drives turbines, which generate power as long as the reactor keeps running.
