Thorium Power
by Thost
Thorium Power is a Forge technology mod centred on the chemical element thorium, with power generation built around it.
What it does
The mod adds a power system based on thorium ore and thorium ingots, with a reactor as its first machine type. Future additions are described as molten salt and pellet reactors, though none are listed in the current release. The author based the design on the thorium reactor concept, which is explored in real life as an alternative to uranium and plutonium fuel cycles.
Thorium Power runs on client and server, so both the server and every player need the mod installed. Files exist for Forge only, for Minecraft 1.20.1, and the source code is public under the MIT License, making it open source.
