MekaNuka
MekaNuka adds Fallout-themed content to Mekanism on Forge, with Fusion Cores that store and release power and ores that spawn in the Wasteland.
What it does
Vanilla Mekanism ores generate in the Wasteland biome, so the mining route runs through the NukaCraft: Fallout world without leaving the Mekanism progression. The mod works with the Mekanism Integration NukaCraft add-on and requires Mekanism, Mekanism Generators and the NukaCraft: Fallout mod.
Fusion Cores can be crafted with ingredients from the Mekanism and NukaCraft sides. Once charged, a core supplies power in the same way as an Energy Tablet, and a single core holds up to 500,000,000 FE. Recharging is handled through the usual Mekanism energy flow, so cores fit into existing power networks.
The server and every player need the mod installed. The build is published for Forge only, for Minecraft 1.20.1, and is distributed as a beta release under All rights reserved, so it is not open source.
Key features
Wasteland ore generation

Craftable Fusion Cores

Rechargeable power storage
A charged Fusion Core releases its energy when used, and it can be recharged after it runs down.
Large energy capacity
Each Fusion Core holds up to 500,000,000 FE, which is enough to power Mekanism machinery for a long period.

Use cases
Powering Mekanism machines
A Fusion Core can serve as a portable power source for Mekanism machines in a base far from a generator network.
Wasteland mining
Players who build Mekanism operations in the Wasteland can gather ores there instead of traveling back to the overworld.
Who it’s for: The mod suits players who run Mekanism alongside NukaCraft: Fallout and want Fallout-themed power and mining. Server owners who run the Wasteland biome also need to install it on the server.
