Im building a base right now but I have a question wich is the best way to power it with a Fussion or a Fission reactor? I already have an underground facility for a Fission reactor that when its done will contain 4 reactors. that Im going to wire up so they send up power to my base on the surface. There I plan to add 4 to 8 advanced solar generators. Then Im going to build producktion factories, alarms, missile defense, 2 or 3 launching platforms, 4 to 6 radar stations and Battery chargeing. Will a 4 core fission reactor make it on its own? (the solar generators is only planned to speed up recharge) How long can I go before I need to place new uranium rods into the reactors? Is a 2 to 3 core fussion reactor better to use?
