Inspired by the classic Minecraft mod NuclearCraft: process uranium and thorium through a long chain of fission fuels, isotopes and reprocessing, all the way to californium and radioisotope thermoelectric generators.
Mods introducing new content into the game.
Version: 0.2.1
Date: 2026-10-08
Bugfixes:
- Recycling no longer runs this mod's processing recipes backwards. Steel plate recycled into spent
heat sources (breaking Fulgora scrap chains), uranium-235 into plutonium-239, and many isotopes
into their decay or irradiation parents. Products of smelting, decay, irradiation, separation and
reprocessing now recycle into themselves, like vanilla plates.
Version: 0.2.0
Date: 2026-10-05
Info:
- Renamed from Nucleartorio to Expanded Nuclear Fission (internal name expanded-nuclear-fission).
Prototype names are unchanged, so saves made with Nucleartorio keep their buildings, items and research.
Features:
- Nuclear robots: four tiers of logistic and construction robots powered by tritium, americium-241,
plutonium-238 and californium-250. They never need recharging, are faster than vanilla, and
tiers 3 and 4 carry 2 and 3 items. A destroyed nuclear robot releases a radiation cloud and
some pollution.
- Relay roboport: needs no electricity; one slow charging pad powered by its americium core.
Interchangeable with the vanilla roboport in the upgrade planner.
- Barite concrete can be placed as a floor (stacked shielding blocks).
- Neutron-doped modules: processing units irradiated with a californium-252 neutron source upgrade
each tier-3 module to a stronger version that makes the machine pollute much more. Startup
setting, on by default.
Bugfixes:
- Uranium leaching has its own name (it showed an unknown key when other mods added results).
Graphics:
- New models for all eight nuclear robots: betavoltaic box drone, americium capsule, plutonium
saucer with an RTG core, californium gimbal drone. Each glows in its isotope's colour.
Changes:
- The relay roboport uses the CMA logistics hub art for now.
Version: 0.1.0
Date: 2026-10-04
Features:
- The NuclearCraft actinide ladder: thorium, uranium, neptunium, plutonium (incl. MOX), americium,
curium, berkelium and californium fuels; 19 new fuels plus the vanilla uranium fuel cell.
- Hot cell reprocessing (Basic and partitioning), neutron irradiator (heat-powered), isotope separator,
decay chamber, centrifuge cascade, fuel fabricator, mineral crusher, arc furnace.
- Fission reactors Mk2 and Mk3 (fuel assemblies with gadolinium control rods), supercritical steam.
- Radioactive decay as Space Age spoilage; waste casks that leak and rupture outside dry cask storage;
vitrification and the geological repository.
- RTGs, isotope heater, tritium lamps, radioisotope beacons, waste artillery shells.
- Optional planet shortcuts (bioleaching, electromagnetic separation, cryogenic reprocessing,
tungsten shielding, Aquilo acids).
