So unless you are doing something crazy which requires to run lots of large ion thrusters on full power permanently, or you have any mods which add some very energy-demanding blocks to the game, one dedicated Uranium refinery will be all you need. So while your refineries will run nonstop for hours after feeding them a cargo container full of uranium ore, your reactor will only have to provide its full output during short and rare peak moments. The fuel consumption of your reactors is linear to their current load. Most of the time your thrusters will be idle (hint: If you want to travel a longer distance, accelerate to max speed, switch off inertia dampeners and just coast). And they will only consume the energy while running on full power. The only thing in the (non-modded) game which consumes power in that order of magnitude are large/large ion thrusters running on full power (33.6 MW each). Those 300 Million Watt are a huge amount of juice. You can reduce that number when you use speed- or yield-modules, but it still seems intuitively much.īut remember that you will likely not run a large reactor on full load at all times. One would imagine that engineers working in the nuclear power industry. So if you want to permanently run a large reactor on full load, you need 7.5 refineries. Two billion years ago parts of an African uranium deposit spontaneously underwent.

A refinery with no upgrade modules takes 90 seconds to produce 1 kg of Uranium Ingots (which, by the way, consumes 90 kg or 33.3 l of uranium ore).

A large/large reactor running on full load takes 12 seconds to burn 1 kg of Uranium Ingots.

So I just checked the times myself using a stopwatch. Never trust a wiki article you didn't vandalize yourself.
