Create Nuclear
With Create Nuclear installed, players build nuclear reactors inside Create, and every reactor carries the risk of a meltdown.
What it does
The addon adds reactors in three tiers, each giving higher energy output and heat capacity. A coolant system built on new fluids such as nitrogen is how players keep a reactor's heat in check and avoid a meltdown. Radioactive items emit ambient radiation, and an iodine system and anti-radiation armor protect the player from it. A meltdown ends in a large nuclear explosion that leaves an Irradiated Land biome behind, which stays hostile. Leaving an old reactor assembled can lead to corruption or an immediate meltdown.
Uranium and thorium ores are added, together with the refining chain that turns them into reactor fuel. Automated setups can start from effectively unlimited inputs such as cobblestone, using the refining steps to draw on Create machinery. The mod needs Create, Create Fabric on Fabric and Fabric API on Fabric. It is open source under the GNU Lesser General Public License v3.0 only, and runs on client and server, so the server and every player need it. Files are published for Fabric, Forge and NeoForge for 1.20.1, 1.21 and 1.21.1.
Key features
Three reactor tiers
Reactors come in progressively stronger grades, each raising energy output and heat capacity over the one before.
Coolant fluids
New fluids, including nitrogen, are routed into the reactor to absorb heat and prevent a meltdown.
Ambient radiation
Radioactive items emit radiation into the area around them, which the player must counter.
Iodine and anti-radiation armor
An iodine system and anti-radiation armor give the player protection from the radiation.
Meltdown explosions
A meltdown triggers a large explosion and leaves a hostile Irradiated Land biome in the world.

Use cases
Automated power plants
Refining chains fed from ores or cobblestone can run on Create machinery to supply a reactor without manual feeding.
Who it’s for: Players who enjoy Create's automation and want a reactor-based power source with radiation hazards. Server owners running a Create modpack can add it, since both sides need the mod.

What the author says
Leaving an old reactor assembled could result in corruption or an immediate nuclear meltdown. 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…
