About
Thorium Reactors adds a thorium-based energy production chain to Minecraft, taking players from mining ores and preparing fuel through building a reactor, exchanging its heat for steam, and generating power with a turbine. Underground resources include up to 11 ores and minerals, such as chromite, graphite, uranium, fluorite, nickel, bauxite, manganese, and pyrochlore; some resources, including cobalt, are obtained as byproducts of ore processing rather than mined directly. A suite of processing machines turns resources into reactor fuel: players produce sodium and potassium from water, combine them with thorium into molten salt, and process uranium through yellow cake, uranium hexafluoride, enrichment, and crystallization to make enriched uranium pellets. Most recipes use a dedicated Thorium Crafting Table with a 5-by-5 crafting area, and machines can be switched off or controlled by redstone. The reactor is a multiblock structure built from casings, glass, valves, a controller, a core, and graphite moderators; its control interface lets players monitor stability, efficiency, temperature, and fuel-rod status. A heat exchanger transfers reactor heat into fluids such as water to produce steam, which drives a separately constructed turbine to generate power. The mod also includes advancements, numerous recipes and resources, and integrations including CC:Tweaked and The One Probe.

No harmful code found
We checked its files and read their code, without running it.
What it can do on your computer
- Connects to the internet
- It has code that can go online, for example to check for updates, load skins or send crash reports. It contacts 1 web address. See Privacy
- Creates settings files
- The mod keeps its settings in the config folder of your game, where you can change or delete them. 2 files in your config folder.
Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.
How we checked
- FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.2 latest files: the newest file for each Minecraft version and loader. The answer above is about the one for a recent version. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
- Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.Read without running it
- Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.Nothing declared about your system outside the game.
- Looked for, not foundWe looked for these in the file and did not find them.Folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.
Privacy
We found nothing it sends about you
We read its code without running it: it contacts 1 web address while you play.
Like any connection, each address it contacts sees your IP address.
Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
How we checked
- Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.The code of its one file, for recent Minecraft versions. See each file in Releases
- 127.0.0.1Talks to a program on your own computer.From a bundled library.Unencrypted (http)Plain http: what is sent to this address is not encrypted on the way.
- Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.Nothing declared about crash reports, usage data or advertisements.
AI
No sign so far that AI was used to make it
We looked for AI tools in its description, files, images and sounds and found none.
We have not read its changelogs and code history yet.
No sign of AI in the game
We found no AI service, AI library or AI model file in its code.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.No AI content or AI features declared.
- Code historyThe public code on GitHub: who made each change, credit lines such as "Co-authored-by", and its files.Not read yet
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found in the descriptionChangelogs not read yet
