Create: Atomic
by mrh0
Create: Atomic adds a nuclear power line to Create, letting players generate kinetic energy from the power atom through multi-block machines.
What it does
The mod introduces a multi-block Nuclear Reactor and a Steam Turbine, along with a Radioisotope Heat and Energy Generator and several modular reactor components. Large reactors built from these parts feed turbines that produce a substantial amount of stress units, which makes the mod suited to players who want bulk power on NeoForge 1.21.1.
Reactor builds are intentionally unforgiving: a poorly balanced setup can overheat and melt down, so careful layout and monitoring matter. A server running it needs every connecting player to have it too. Files are published for NeoForge only, for 1.21.1, with 1.3.2 as the latest file from 2026-10-04. The code is released under the MIT License and is open source.
Key features
Multi-block nuclear reactor
A reactor assembled from several blocks converts the power atom into heat and energy for connected machines.
Steam turbine
The turbine takes steam from the reactor and produces rotational force that Create machinery can use.
Radioisotope generator
A generator that turns radioisotope heat into energy, adding a smaller power source to a base.
Modular reactor components
Several interchangeable parts let players shape the reactor layout to their own power needs.

Use cases
Bulk power for Create factories
Large reactors and turbines can supply stress units to a big mechanical base without many small generators.
Who it’s for: Players on NeoForge 1.21.1 who already build Create machinery and want a nuclear-themed energy source, including server owners who plan a shared power grid.
How it compares
Create: Turbines is open source under the MIT License and also runs on client and server for NeoForge 1.21.1, but it focuses on turbine machinery rather than a reactor. Nuclearism is client and server for NeoForge 1.21.1 and is not open source, since its license is All rights reserved. create: nuclear industry is open source under the MIT License and shares the same NeoForge 1.21.1 target.

About: Create: Atomic adds a new way to generate kinetic energy by leveraging the power of the atom! Build large multi-block Nuclear reactor, to power turbines which generate large amount of SU, however make sure to not get carried away our you might end up having a meltdown!
