Uranium can be directly placed into a Nuclear Boiler, or into a Chemical Extractor, which produces two to three Yellowcake. Each Yellowcake can be boiled to create 1 dm3 of Uranium Hexafluoride, which is a more effective and produces more Uranium Hexafluoride than direct boiling per Uranium Ore. As Yellowcake can produce more Uranium Hexafluoride, it can create more Uranium-235 and Uranium-238 when centrifuged.
