The Nuclear Generator is balanced, its basically fuel generator but nuclear, let me explain, To make fuel you need to get oil and put it in a refinery which uses energy to make fuel, Oil can be produced in town resources or extracted from the ground. The Uranium can be made using sf machines and stuff but it takes time and to automate it you'll also need power or you can get it through town resources or extract it, Just like the oil aka fuel.
So why is the fuel balanced BUT NOT the uranium?
If its about the byproducts of the nuclear generator and other disabled items, you can just remove the output of the generator completely or even better return the byproducts and allow them to be used as android fuel (such as plutoniom)
Please don't just say "no! its unbalanced" and stuff Because it is literally the same thing as fuel and oil.
If it gave too much energy in the past just reduce its energy output and make it require FULL uranium ingots not piles nor chunks.
bye!
