A 5x5 smelter that burns uranium fuel cells. Optionally runs a water cooling loop: water in, hot steam out, both passed on to the next machine. Condense the steam back into water in a chemical plant, or run it into a steam turbine through a pump.
Mods introducing new content into the game.
Version: 1.4.0
Date: 05.09.2026
Features:
- New startup setting "Steam temperature": 500 C as before, or 165 C. Pick 500 C to turn the
steam into electricity efficiently. Pick 165 C if you care about the water and condensation
logistics instead.
Changes:
- Both fluid buffers now follow the steam temperature and still hold 100 seconds of water
Version: 1.3.1
Date: 04.09.2026
Balancing:
- The nuclear smelting recipes now consume a tenth of the water they used to. Steam output is
unchanged. A Heat exchanger turns 10.3 water/s into 103 steam/s. The furnace now does the
same ratio. Thanks to NOiZE for spotting it.
- The water buffer shrank from 1000 to 100 to match the lower consumption. It still holds
100 seconds of water, and a row of chained furnaces no longer needs a small lake to start up.
Version: 1.3.0
Date: 03.09.2026
Features:
- Recipe productivity technologies now cover the nuclear smelting recipes. Whatever raises the
productivity of a recipe raises its nuclear smelting variant by the same amount, no matter
which mod the technology comes from.
Modding:
- Added api.mirror_productivity() for mods that add or change recipe productivity technologies
in their own data-final-fixes and are therefore too late for the automatic pass.
Version: 1.2.3
Date: 06.08.2026
Balancing:
- Pollution and energy usage now scale with the "Crafting speed" startup setting.
Version: 1.2.2
Date: 06.08.2026
Changes:
- The generated nuclear smelting recipes no longer clutter the player's crafting screen.
Selecting them in the Nuclear Furnace is unchanged. Thanks to kittah_khan for the suggestion.
Version: 1.2.1
Date: 05.08.2026
Minor Features:
- Added heating glow effect for the reactor.
Version: 1.2.0
Date: 02.08.2026
Features:
- Data stage API for other mods: require("__nuclear-furnace__.api") and register your own
crafting categories or single recipes to have nuclear-smelting variants generated for them.
Check the mod description for details.
Version: 1.1.0
Date: 01.08.2026
Features:
- New startup setting "Cheaper recipe".
- New startup setting "Cheaper technology".
- Both settings are aimed at Space Age, where the furnace competes with the foundry, but work
in the base game too.
Version: 1.0.0
Date: 01.08.2026
Major Features:
- Initial release
