    About

    Reactor Stuff is an IndustrialCraft addon that expands nuclear power with new ores, reactor fuels, breeding materials, neutron sources, and radioactive-isotope generators. Its four ores are uranium, thorium, blazonium, and terminium; blazonium occurs in the Nether and burns entities that step on it, while End-found terminium can teleport entities and can swap places with nearby End Stone, especially when exposed to water. The fuels add different reactor behaviors: thorium produces half the heat and power of uranium but lasts twice as long and breeds U233, while TRIGA throttles output as core heat rises to reduce the risk of reactor explosions. Elerium offers high output and a long lifespan but cannot sustain a chain reaction, so it needs an external neutron source; depleted elerium leaves Lawrencium, and depleted terminium yields Californium. Blazonium output rises with reactor heat, reaching up to nine times the power of uranium, and its depleted fuel converts its uranium filler into plutonium; terminium fuel also produces Californium, which can power generators. The mod adds an infinite-durability Americium-Beryllium reflector that boosts nearby fuel rods without generating heat, plus radioisotope thermoelectric generators powered by plutonium, americium, lawrencium, or californium for steady RF output. It also includes Mjolnir, a pickaxe-axe weapon that can call down lightning when enchanted with Power, along with terminium tools that teleport mined blocks into the player's inventory and blazonium tools that smelt mined blocks and set entities ablaze.

    In-game changes

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.12.2.

    No harmful code found

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.12.2.

    We checked its files and read their code, without running it.

    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 · The latest file checked, last on 16 Oct 2026
    • 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.
      1 latest file. It is not for a recent Minecraft version, so the answer above is about it. 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.

    Privacy

    We found nothing it sends

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.12.2.

    We read its code without running it: it contacts no web address while you play.

    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 · Its one file read
    • 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 Minecraft 1.12.2. See each file in Releases

    AI

    No sign that AI was used to make it

    We looked for AI tools in its texts, files and images and found none.

    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.
