NuclearCraft (1.21 Port of https://www.curseforge.com/minecraft/mc-mods/nuclearcraft-neoteric)

This project brings the classic NuclearCraft experience to Minecraft 1.21, reintroducing advanced nuclear technology, complex resource chains, and high-risk/high-reward energy systems for modern gameplay.

⚛️ Features

  • Fission Reactors
    Build customizable multiblock fission reactors using various fuels. Manage heat, efficiency, and cooling to prevent meltdowns while maximizing power output.

  • Fusion Reactors (Endgame)
    Unlock powerful fusion technology for massive energy production once you progress far enough.

  • Advanced Fuel Processing
    Refine raw materials into nuclear fuels through multi-step processes, including isotope separation and fuel fabrication.

  • Radiation System
    Exposure to radiation adds a survival challenge—players must use protective gear and manage contamination carefully.

  • New Ores & Materials
    Adds uranium, thorium, and other nuclear-related resources, expanding mining and crafting progression.

  • Machines & Automation
    Includes processors, centrifuges, and other machines to automate complex production chains.

🎮 How This Changes Gameplay

This mod transforms Minecraft from a simple survival experience into a technical engineering challenge:

  • Players must plan and design reactor layouts, balancing efficiency and safety.

  • Progression becomes deeper, requiring long-term resource management and automation.

  • Mistakes have consequences—reactor failures and radiation leaks can damage your world and character.

  • Encourages large-scale builds and infrastructure, making it ideal for tech-focused playthroughs and modpacks.

🌍 What Makes This Mod Unique

Unlike basic power-generation mods, NuclearCraft emphasizes realistic systems and meaningful complexity. Every step—from mining uranium to stabilizing a reactor—requires thought, experimentation, and optimization.

Whether you're creating a compact power plant or a massive nuclear facility, this mod offers a rewarding experience for players who enjoy deep mechanics and engineering gameplay.
