Note that the Chemical Extractor processes one Uranium Ore to three Yellowcake, therefore more Hexafluoride gas is obtained by refining the latter at the expense of time and power.
As of 1.1.4 there is no way to pipe the Uranium Hexafluoride gas, so the Centrifuge must be placed next to the Nuclear Boiler.
Notice that wiring up this machine to an advanced energy cube or higher directly will make it explode. You may need to use a 120v Transformer or use a 120v energy source in order for it to work.
