About this project

What does Mekanism: Nuclear Expansion add?

Mekanism: Nuclear Expansion

**Take Mekanism beyond Ultimate.**

**Mekanism: Nuclear Expansion** is a late-game expansion for Mekanism focused on nuclear processing, rare materials, advanced automation and two new progression stages: **Nuclear** and **Quantum**.

Process Spent Nuclear Waste into valuable metals, build faster factories, automate complex chemical production, expand your storage and transmission networks, and push your Mekanism infrastructure into a new endgame.

Nuclear Expansion is built as a **separate add-on** and does not modify Mekanism's internal tier enums or require a patched version of Mekanism.


☢ Nuclear Processing

Nuclear Expansion introduces a complete processing chain for **Spent Nuclear Waste**.

Progress through multiple chemical stages to extract:

  • **Palladium**
  • **Iridium**
  • **Rhodium**

These materials are then used throughout the Nuclear and Quantum progression.

The processing chain uses dedicated machines such as the:

Nuclear Enricher

Processes Nuclear Expansion's nuclear solutions and chemical stages.

Nuclear Reprocessor

Handles the main rare-metal extraction process and produces Palladium, Iridium and Rhodium.

The system eventually converts processed nuclear waste into **Nuclear Water**, a final non-radioactive product used in higher-tier progression.


⚛ Nuclear Tier

Go beyond Mekanism's Ultimate tier with a complete addon-owned **Nuclear Tier**.

Nuclear machines are designed to visually and mechanically fit alongside Mekanism while remaining completely separate from Mekanism's internal tier system.

Nuclear content includes:

  • Nuclear Energy Cube
  • Nuclear Fluid Tank
  • Nuclear Chemical Tank
  • Nuclear Bin
  • Nuclear Induction Cell
  • Nuclear Induction Provider
  • Nuclear Universal Cable
  • Nuclear Mechanical Pipe
  • Nuclear Pressurized Tube
  • Nuclear Logistical Transporter
  • Nuclear Thermodynamic Conductor
  • Nuclear Tier Installer
  • Nuclear Speed Upgrade
  • Nuclear Energy Upgrade

Nuclear equipment uses the tier's characteristic **yellow accents**.


🏭 Nuclear Factories

Upgrade Mekanism's factory progression with Nuclear factories capable of **11 simultaneous processes**.

Available factory types include:

  • Smelting
  • Enriching
  • Crushing
  • Compressing
  • Combining
  • Purifying
  • Injecting
  • Infusing
  • Sawing

Factories support Mekanism-style automation, side configuration, redstone control, sorting and upgrade systems.


⚗ Parallel Chemical Oxidizer

Need more Chemical Oxidizer throughput?

The **Parallel Chemical Oxidizer** is a specialized tierless machine with **4 completely independent processing lines**.

Each line has its own:

  • Item input
  • Processing progress
  • Chemical output tank
  • Filter
  • Priority
  • Lock state
  • Auto-eject control
  • Dump control

The machine directly uses standard **Mekanism Oxidizing recipes**, meaning existing recipes and datapacks can work without requiring a duplicate recipe system.

It supports normal Mekanism **Speed** and **Energy Upgrades**, side configuration and advanced chemical output routing.


🟣 Quantum Tier

The endgame continues beyond Nuclear with the **Quantum Tier**.

Quantum uses a distinctive visual style based on **very dark purple and neon green accents**.

Quantum progression includes:

  • Quantum Alloy
  • Quantum Control Circuit
  • Quantum Core
  • Quantum Matrix
  • Charged Quantum Core
  • Quantum Template
  • Quantum Tier Installer
  • Quantum Speed Upgrade
  • Quantum Energy Upgrade
  • Quantum Efficiency Upgrade
  • Quantum Processing Upgrade

And a complete set of Quantum infrastructure:

  • Quantum Energy Cube
  • Quantum Fluid Tank
  • Quantum Chemical Tank
  • Quantum Bin
  • Quantum Induction Cell
  • Quantum Induction Provider
  • Quantum transmitters
  • **9 Quantum Factories with 13 processing lanes**

Quantum is designed as a true late-game progression step rather than simply another recolored tier.


🔬 Quantum Materializer

The **Quantum Materializer** is a dedicated high-end machine used for advanced Quantum components.

It combines:

  • Item input
  • Nuclear/Quantum chemicals
  • High energy consumption

to manufacture some of the most advanced components in Nuclear Expansion.

The Quantum Materializer is fully integrated with JEI and automation systems.


🔨 Advanced Smithing Table

Nuclear Expansion includes an **automatable Advanced Smithing Table** for more complex progression recipes.

Its custom recipe system can combine:

**Template + Base + Addition + Fluid + Chemical**

This allows Nuclear and Quantum upgrades to use more involved Mekanism-style production chains instead of relying only on standard crafting recipes.


☢ Radiation & Storage Utilities

Nuclear Expansion also includes several utility blocks designed for large automated bases.

Radiation Scrubber

Consumes FE to gradually reduce nearby Mekanism radiation sources.

Advanced Radioactive Waste Barrel

A high-capacity storage block restricted to radioactive chemicals.

Multi Chemical Buffer

Provides **4 independent chemical tanks** in a single block.

Multi Fluid Buffer

Provides **4 independent fluid tanks** in a single block.

These blocks use Mekanism-style interfaces and are designed for automation-heavy factory layouts.


💾 ME Nuclear Solution Cells

Dedicated storage cells are available for Nuclear Expansion chemicals when using compatible AE2 integrations.

Available capacities:

  • 256,000 mB
  • 512,000 mB
  • 1,024,000 mB
  • 2,048,000 mB

Designed for use with **Applied Energistics 2 / Applied Mekanistics**.


⚙ Configuration

Most important gameplay and balancing values can be changed through:

config/nuclearexpansion-common.toml

Configurable systems include machine energy usage, processing times, storage capacities, factories, the Parallel Chemical Oxidizer, Quantum machines, ME cells and utility blocks.

The configuration is also accessible through NeoForge's Mods menu.

This makes Nuclear Expansion suitable both for normal gameplay and customized modpacks.


🔌 Optional Mod Integrations

Nuclear Expansion includes optional compatibility with several mods.

Applied Energistics 2

Storage and automation support.

Applied Mekanistics

Mekanism chemical integration with AE2 networks.

JEI

Recipe categories, catalysts and machine recipe displays.

Productive Bees

Additional Palladium and Rhodium progression.

Mystical Agriculture

Integration with Iridium resources.

Almost Unified

Common material tags for Palladium, Iridium and Rhodium.

Create

Optional Milling, Crushing, Compacting, Mixing and Sequenced Assembly recipes.

**All integrations are optional.**

Installing Nuclear Expansion does not require any of these optional mods.


📖 In-Game Guide

Nuclear Expansion includes its own dependency-free **Nuclear Expansion Guide** to help explain progression and major systems directly in-game.


Requirements

  • **Minecraft 1.21.1**
  • **NeoForge 21.1.194+**
  • **Mekanism 10.7.19.85**
  • **Mekanism Generators 10.7.19.85**
  • **Java 21**

Mekanism and Mekanism Generators are required.


Development Status

Mekanism: Nuclear Expansion is under active development.

The mod is playable, but some recipes, balance values, visuals and experimental systems may change between releases.

The experimental **Advanced Waste Tank / Radioactive Waste Storage Multiblock** is currently disabled while it is being redesigned and stabilized.

More Nuclear and Quantum content, automation options and mod integrations are planned.
