I decided to make a Mk3 of my Uranium production facility to go with my Hyperion blueprint book. Build time was around 4 hours.
Total output is around 500 to 600 U235 per minute.
To start it takes in upto 133 Uranium ore per second into the lower warehouse. This is them processed by the bottom two Centrifuges and the Uranium 238 is then put back into the warehouse along with any U235. The next 6 centrifuges process both Uranium types. A complex combination of circuit conditions and filters sends them both to the next warehouse in a perfect ratio which never fails. Until the U235 is produced the lights are red. But when U235 is produced then the lights will glow green.
