About
NuclearCraft adds a nuclear engineering progression centered on designing and operating multiblock fission and fusion systems. Its fission options include solid-fuel and molten-salt reactors, supported by a detailed fuel system with multiple fuel types; fusion uses combinations of fuels in large tokamak reactors. Players can build heat exchangers, condensers, steam turbines and decay generators to work with the heat and energy produced by these systems. The mod also includes a Fallout-style radiation system, along with additional materials, weapons, tools and armour. It supports Forge Energy, RF, IC2 EU and GTCEu EU, and integrates with JEI, CraftTweaker recipes and Mekanism gases.
Written from Modrinth and CurseForge . How we write it
In-game changes
It has no file for a recent Minecraft version. This is about its files for Minecraft 1.7.10 to 1.12.2.
Adds 1 projectile, 5 other entities, 54 advancements, 11 loot tables and 13 sounds.
Counted from the names and data files in the mod, so the list may not be complete.
Keeps all of vanilla Minecraft's textures, models and sounds.

Security
No harmful code found
It has no file for a recent Minecraft version. This is about its files for Minecraft 1.7.10 to 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
- 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.5 latest files: the newest file for each Minecraft version and loader. None is for a recent Minecraft version, so the answer above is about all of them. 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.The internet, folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.
Privacy
We found nothing it sends
It has no file for a recent Minecraft version. This is about its files for Minecraft 1.7.10 to 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
- 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 all 5 files, for Minecraft 1.7.10 to 1.12.2. See each file in Releases
- 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 that AI was used to make it
We looked for AI tools in its texts, files, images, sounds and code history 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.
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.Nothing found
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found7 of 40 changelogs read
- Its filesFiles that AI coding tools leave behind (like AGENTS.md), and the texts inside the files you download.Nothing found
- Images in its filesHidden data in the images of the files you download, where AI image tools write their name and settings.Nothing found773 images read
- Sounds in its filesThe tags of the sound files in the files you download, where some AI music tools write their name.Nothing found13 sounds read

Known conflicts
These projects do not work together with NuclearCraft: their authors or NuclearCraft's author say so. If you install both, the game can crash or some features can stop working. Some of them do the same job as NuclearCraft, so you only need one.
