The Nuclear Energy Reactor Mod is an intended solution for late game electrical problems.
The creator, Frosty was sick of having many different generators to constantly fill up, and wanted a better option for late game, without completely replacing the original generators. 
This mod was created with the intention to have a higher tier source of power storage. 
The Nuclear Reactor Bank functions as normal, with the exception of requiring Nuclear Cells instead of standard batteries. 
The Nuclear Reactor is approximately 4x as durable, and recharges banks approximately 4x faster than a standard generator.
Capacity of the fuel tank has been increased to 25K.
Output has been increased to 3000W.

Crafting of the Nuclear Battery Bank requires you to learn the standard Battery Bank schematic, and will require the use of a workbench in game.
You will be required to craft or find a new item “Nuclear Cell” and “Concentrated Uranium”, which is one of the pre-requisites for crafting the Nuclear Reactor Bank.

Treat this as you would a normal generator, using Cells in place of batteries.
