It would be nice for there to be alternate sources of power. For this I have a few ideas.
-Oxygen and hydrogen being used together to produce power directly. They should probably provide less than the input used to produce oxygen/hydrogen from their respective generators. This however might only be useful in emergency situations, this should be compatible with all reactors.
Maybe some exaggeratedly low power renewable energy sources with their own unique cons so as to not make them overpowered....
