NuclearCraft is a mod that aims to bring the concepts of quantum and relativistic particle physics to Minecraft. The mod adds a total of 9 minerals to the world generation, including copper, tin, silver, copper, uranium, lead, thorium, plutonium, boron, and lithium. These minerals can then be processed and fused with specialized machinery to develop new items such as weapons and armor, among others.

The mod adds reaction generators, special furnaces, mineral crushers, isotope separators and fission reactors, as well as other electric machines. The mod is compatible with some tech mods like Industrial Craft and Mekanism.
