Radioactive Elements


Adds a nuclear isotope industry. Polonium, cobalt, strontium, yttrium and californium cartridges are needed for science, rockets and more. With or without Space Age enabled, but you need to own it.

Version: 0.7.0
Date: 2026-11-02
  Major Features:
    - Cerys support. Its repaired Fulgoran reactor burns a high-flux target and makes a californium cartridge in one burn, without the two advanced reactor campaigns.
    - Mixed-oxide actinide recovery turns spent mixed-oxide cells into actinide concentrate, uranium and plutonium in a hot cell.
    - Researched on Cerys as High-flux irradiation. Nothing in Cerys itself changes.
Version: 0.6.0
Date: 2026-11-02
  Major Features:
    - Space Age and Quality support. The first rocket, the rocket silo and level 3 modules stay as they are.
    - Supercapacitors take insulation, and electromagnetic plant research needs Gamma processing.
    - Cryogenic science takes lithium foil, made on Aquilo with yttrium from a shipped strontium parent.
    - Promethium science takes samples assayed on a platform with a californium cartridge, plus avionics. Railgun turrets take avionics too.
    - Adds the lithium rolling mill and asteroid neutron analyzer, with Space Age only.
  Bugfixes:
    - Scripted machines stop when frozen, and accept ingredients of any quality.
Version: 0.5.1
Date: 2026-11-02
  Changes:
    - Blueprints now carry a cartridge machine's setting for when to return its cartridge.
Version: 0.5.0
Date: 2026-11-02
  Features:
    - First public version for the base game.
    - Four production lines: polonium, cobalt, strontium and yttrium, and californium.
    - Adds 8 buildings and 5 reusable isotope cartridges. Yellow science, the rocket silo, rocket parts and level 3 modules now need their products.
