About this Mod
As of the 1st of June 2025, all future updates for ampz mods will require Voltaic API, and not Electrodynamics, in order to function. This update affects all the mods and brings world breaking changes, which are written in the changelogs. Note that this should however not corrupt your world. If you have such issues reach out on our discord channel!

Nuclear Science intends to relieve the burden of electricity generation in Minecraft. Advanced technologies like Fission and Fusion reactors, alongside particle accelerators, are included in this mod. Rare items like antimatter and dark matter also exist, which are used to craft different explosives and theoretical power generators.
Other than providing energy, the mod introduces elements of nuclear physics into the game, making gameplay more scientific and realistic. The different machines try to follow real physics and chemistry to enhance this experience.
This project is based upon Voltaic and Electrodynamics and requires these mods to run.
