Quote from description: "One reactor is able to support 40 large turbines."
Whereas with some in game it seems that a reactor is actually only able to support 20. For a total electric output of 2GW

Also it feels like nuclear power is much more expensive than fusion per GW generated in terms of the costs and complexity of fuel production and power plant machine costs and power plant setup complexity. Feels a bit unbalanced at first glace

Yeah nuclear power is just a waste to focus on, You either has to make a farm to get more of that special fuel and just go at it. Even then a nuclear power just drain to fast and drain the fuel to fast to get anything back at reasonable rate. Right now its just better to use it for research and ammo. Nothing else.

You should just skip nuclear energy and go straight to fusion because mass producing that material is far far easier.
