About this Mod

⚠️ WARNING FOR V2 UPDATE ⚠️

If you are updating an existing world to V2, you MUST completely dismantle your active reactors before updating!

Leaving an old reactor assembled could result in corruption or an immediate nuclear meltdown.

About

Create nuclear is a mod that adds a whole nuclear system to the create mod. An optimized reactor can now produce over eight millions SU.

Create nuclear also adds Uranium and Thorium ores, and all the refining process to create and power the reactor automatically. You can even build setups from infinite sources like cobblestone with a complex refining process that exploits all the potential of create appliances.

New in V2:

  • Reactor Tiers: Build Tier 1, Tier 2, and Tier 3 reactors for higher energy outputs and heat capacities.
  • Coolant System: Use new fluids like Nitrogen to balance your reactor's heat and prevent meltdowns.
  • Radiation: Radioactive items now emit ambient radiation. Protect yourself using the new Iodine system and Anti-Radiation armor.
  • Meltdowns & Biomes: A reactor meltdown will now trigger a massive nuclear explosion, leaving behind a hostile Irradiated Land biome.
