What it does

Players can build oil refineries, a steel alloy furnace, a Chicago Pile and a nuclear reactor, along with research reactors, isotope processing, a foundry, a mechanical bore and a nuclear bomb. A radiation system tracks the exposure these machines create. The author describes it as a nuclear tech mod with some new features, comparable to HBM's Nuclear Tech Mod. Geckolib is required, and the mod warns that JEI compatibility is limited.

Nuclearism runs on client and server, so the server and every player need it. It is published for NeoForge 1.21.1 only, with file 1.7.1 as the latest release, marked beta, and under All rights reserved, which means it is not open source.

Key features

  1. Nuclear machinery

    Oil refineries, a steel alloy furnace, a foundry and a mechanical bore work together to process ores into materials.

  2. Reactor chain

    A Chicago Pile, a research reactor and a full nuclear reactor cover the stages from early experiments to power generation.

  3. Radiation and bombs

    A radiation system and a nuclear bomb add hazards to the new ores and isotopes.
