NuclearCraft-Neoteric

This branch starts the Minecraft 26.2 / NeoForge 26.2.0.88 port. The alpha.13 preview includes dark UI for all 27 Machines-tab screens, all 17 Power-tab blocks, original processor recipes and crafting, all 493 source fluids, naturally generated ores, speed/energy upgrades, side automation, and optional JEI integration. Screen geometry and artwork were compared with a running upstream 1.21.1 NeoForge client. Original Pump collectors appear in creative tabs; all ten crafting/assembly and production paths are tested. Nine original virtual vein recipes, Analyzer reports, saved mining depletion, and weighted JEI displays are restored. Charging Station now preserves neighboring block faces through its glass, matching the original 1.21.1 block's non-occluding rendering behavior. Original progress artwork now omits its baked light-panel background in dark machine/JEI views. Original system tabs are registered; Fission and Accelerator show existing components. Fusion now has its original core, cage, five magnet/RF tiers, structure validation, reaction physics, cooling, sounds, renderer, dark menu and 21 fuel / four coolant JEI recipes. Heat exchangers now have their original six blocks, crafts, hot/cold loops, radiators, automation, three dark menus and six JEI recipes. Solid-fuel fission now has original validation, all 43 heat sinks, 109 fuels, FE/steam generation, coolant ports, irradiation, native automation, save/pause behavior, dark controller/port menus and JEI transfer/reload. Three empty system tabs await their content. This is still an incomplete port: radiation/corium/fallout, MSR, turbines, custom equipment charging, and several integrations remain unavailable. See the status guide for machine-specific limits; complete gameplay parity is not claimed. See the port status and testing guide. Operator command /nc multiblock checks/builds test blueprints. Working Leacher and four-Pump construction is available, as are original fission, fusion and heat-exchanger guides; remaining presets report their unported blocks and place nothing. See command usage and limits. The alpha.13 validation report records the real 1.21.1 reference comparison, final tests, package audit, and JAR hash. The current scope is the entire mod; the registered preview subset is not a complete port. Further content and gameplay systems are being migrated. The upstream 1.21.1 feature description below describes the original mod, not the features available in this preview.

Re-creation of the classic NuclearCraft mod for modern Minecraft (Forge 1.21.1, Java 21). NuclearCraft-Neoteric brings a full nuclear-tech progression chain to the game: ore processing, fission reactors with configurable fuels and heat sinks, molten salt reactors, fusion cores, particle accelerators, target chambers, kugelblitz (black-hole) reactors, steam turbines, in-situ leaching, and a chunk-based world radiation system that actually rewards (and punishes) how you build.

Overview

• Mod id: nuclearcraft
• Minecraft: 1.21.1 (Forge)
• Energy: Forge Energy (FE/RF); Mekanism and GregTech CE: Unofficial interop where present
• Integrations: JEI, EMI, KubeJS, ComputerCraft, OpenComputers v2, AE2, Refined Storage, Mekanism, TIS-3D, Patchouli, Ponder
• In-game guide: Patchouli Operator's Handbook
• Downloads: https://curseforge.com/minecraft/mc-mods/nuclearcraft-neoteric
• Dev builds: GitHub Actions tab → latest artifact

Features

• Ore processing chain - crushers, washers, centrifuges, electrolyzers, infusers, melters and assemblers feeding a deep materials tree (uranium, thorium, plutonium, americium, curium, californium and beyond).
• Fission reactors - multiblock cores with configurable solid fuels, moderators, reflectors, heat sinks, steam mode, neutron flux, and meltdown consequences.
• Molten Salt Reactors - liquid-fuel cores: pump carrier salt through a chamber of fuel pebbles, manage coupled temperature/reactivity with a self-stabilizing negative feedback, and ship the heat out as hot salt to a heat exchanger.
• Fusion reactors - toroidal plasma ring built from electromagnets and RF amplifiers, fed by fuel/coolant recipes.
• Particle accelerators - linear and (WIP)toroidal beam lines with magnets, RF cavities and configurable particle sources.
• Target chamber - beam-driven transmutation, detector readouts, antimatter production chain.
• Kugelblitz reactor - 11×11×11 photon-ignition chamber for mini cool looking blackhole.
• Steam turbines - rotor shafts, blade tiers, coil materials, steam/exhaust recipes and a transparent energy formula.
• In-situ leaching - ore-vein system with leachers, pumps and research papers as an alternative to traditional mining.
• World radiation - since 1.21 radiation moved to separate mod Nuclear Radiation
• World generation - new biome, new dimension with custom structures. Mini boss. Ores
• Anomalies and crystals - Environmental hazards in Wastelands and buffs.
• Nuclear weapons - Pu-239 / fission and fusion bombs with simulated blast, fallout and structural damage.
• Engineer's Crafting Table - powered autocrafting terminal: load storage containers and encoded patterns, feed it power, and it assembles to spec one operation per tick. Scriptable via ComputerCraft and OpenComputers v2 peripherals.
• Universal pipes - single conduit that transports items, fluids and energy at once; pipe connectors set per-medium pull/push/auto modes and optional redstone gating.
• Energy & storage - Forge Energy (FE/RF) throughout, with Mekanism and GregTech CE:U interop, plus voiding/buffering storage tiers.
• Mod integrations - JEI, EMI, AE2, Refined Storage, ComputerCraft, OpenComputers v2, TIS-3D, KubeJS, Patchouli, Ponder.
• In-game guide - Patchouli Operator's Handbook covering every multiblock and recipe path.
