Expanded Nuclear Fission

by trentk

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.

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).
