Strontium

by Alkrist

Strontium is a Forge addon for Create and The Factory Must Grow that brings nuclear machinery, radiation and contamination into a Create-style factory setting.

ForgeClient and serverMIT License1.20.1 – 1.20.6

What it does

Strontium adds a nuclear reactor with matching equipment, basic machinery for processing uranium, and a simple radiation and contamination system that carries some toxicity. Structures and NPCs also spread through the world, and they are tied to the optional TaCZ content.

Both required dependencies, Create and Create: The Factory Must Grow, must be present, and the mod is meant to sit alongside them as a nuclear science layer. Timeless and Classics Zero is optional: installing it, along with SmartBrainLib, enables the TaCZ-related content such as the NPCs and structures. Strontium is built for client and server, so the server and every player need it, and it is released under the MIT License without being open source.

Builds cover 1.20.1 – 1.20.6, with 0.3-1.20.1 for 1.20.6 as the latest Forge file, published on 2026-03-25 on the alpha channel.

Key features

  1. Nuclear reactor

    A reactor and its supporting equipment give the factory a nuclear power source to build around.

  2. Uranium processing

    Basic machinery handles uranium, turning raw material into the inputs the nuclear parts need.

  3. Radiation and contamination

    A simple radiation and contamination system adds toxicity, meant to make survival harder and give builds a purpose.

  4. Structures and NPCs

    Structures and NPCs generate across the world, adding places and people to explore when TaCZ content is enabled.

Is Strontium ready for a stable world?

The author describes it as an early experimental version with bugs and recommends against using it in important worlds. It is updated gradually.

What the author says

NOTE: right now this is a very early development experimental version, featuring only some basics, don't expect much from it. Bugs are totally present, so don't use it in your important worlds. The mod will be updated gradually. The idea came to my mind after playing a lot with HBM Nuclear Tech + Techguns modpack on…
