Uranium-235

Uranium-235 is an in-game item in the item category. It is the Factorio representation of the U-235 isotope used in the game's nuclear-related systems. The term appears in the wiki as part of the uranium processing and nuclear power topic cluster and is connected to several related articles that explain the sources, processing equipment, and other uranium isotopes. Related articles include:

• Uranium ore — the raw resource from which uranium isotopes are obtained.
• Uranium-238 — the other uranium isotope featured alongside Uranium-235.
• Centrifuge — the processing machine used to separate and refine uranium isotopes. Practical notes and navigation tips:
• Consult the Uranium ore article to learn where and how raw uranium is mined and what infrastructure is involved in its collection and delivery to processing facilities.
• The Uranium-238 article provides the complementary isotope context; together, the uranium isotopes form the core of in-game nuclear material systems.
• The Centrifuge article covers the processing equipment used to convert raw uranium into refined isotopes and explains production throughput and setup considerations relevant to handling Uranium-235.
• When documenting or configuring production chains, refer to the related pages to trace the entire lifecycle from ore extraction through centrifuge processing to any downstream uses or recipes that require refined uranium isotopes. This article exists primarily as the encyclopedia entry for the Uranium-235 item and as a hub linking the mining, processing, and machinery articles that together describe the uranium workflow in Factorio. For step-by-step production setups, machine specifications, and recipe requirements, follow the linked articles listed above.
