Yellowcake
Yellowcake is the first step in uranium enrichment. It is a fine yellow powder, emitting the same radiation as unprocessed uranium (0.5 RAD/s) but without the pyrophoric hazard.
Production
It is produced in a chemical plant with the following recipe:
500mB
Uses
Although it can be made into granular blocks for storage, it is recommended that it be made into uranium hexafluoride for processing in a gas centrifuge:
1,000mB
1,200mBSince fluorite is an output of uranium hexafluoride processing, both it and sulfur can be cycled through the enrichment process without losses.
Trivia
- In real life, yellowcake is not necessarily yellow; thanks to modern changes in milling methods, its color can range from yellow to orange to even black.
- Despite this, yellowcake can be produced using peroxide and sulfur, so the in-game depiction is still accurate.
- Curiously, a handful of yellowcake blocks can be found inside the Geyser structure.
