Nuka Engineering
Nuka Engineering adds machines for Nukacraft players, starting with nuclear generators that run on fusion cores and an ammunition press for crafting ammo in bulk.
What it does
Nuka Engineering requires NukaCraft: Fallout on Forge for 1.20.1, and Immersive Engineering is optional but recommended. The machines are built with Immersive Engineering's power transmission, conveyors and assemblies in mind, so they connect into that ecosystem cleanly. A connector cable attached to the output port on top of a generator extracts its power.
Nuclear generators accept fusion cores and produce power while a core is inserted. They render the inserted core, and naturally spawning generators have a 20% chance to appear with a core already loaded at 30% to 90% charge. The generator is craftable at a workbench, and the machines provide power to the machine above them. The add-on works alongside Lore-Friendly Automation Addon Nukacraft and the Nukacraft recommended mods, including Fusion Core Generator Overhaul.
The mod is client and server, so both the server and every player need it. Its latest Forge file is 0.1.2 for 1.20.1, published on 2026-06-13 on the beta channel. The first release was on 2026-06-11. The code is under All rights reserved, so the mod is not open source.
Key features
Nuclear generators
Generators burn fusion cores for power, with the charge level shown on the block and a connector on the top output port.
Ammunition press
A machine that mass produces NukaCraft ammo, with the ammo type locked in from a list so one type is crafted at a time.
Conveyor-fed input
Materials can be inserted by hand or through a conveyor from the back, and finished ammo leaves through the output conveyor.
Workbench recipes
Ammo recipes match the ones shown at the workbench, so players can check a recipe the same way in either place.

Use cases
Who it’s for: Players running NukaCraft: Fallout who want power and ammunition machines, and players who already use Immersive Engineering for conveyors and power transmission.
How it compares
Survival power armor is a server-side only Forge mod for 1.20.1, so players join without installing it, and it is not open source. Void Generator is a client and server Forge mod for 1.20.1 – 1.20.2 under All rights reserved. NuclearCraft is open source under the MIT License, client and server, but only for 1.12.2, so it does not cover the same version as Nuka Engineering.
