Yellowcake

Yellowcake, in all its yellow-ness

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).

Production

It is produced in a chemical plant with the following recipe:

 Chemical Plant

500mB 2 2

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:

 Chemical Plant

1,000mB 4 1,200mB 2

Since 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.
