Yellowcake

Yellowcake is the first step in Uranium enrichment. As expected, it is yellow.

Production
Yellowcake is produced in the Chemical Plant.

1 piece of Yellowcake requires:
 * 1 Uranium powder
 * 2 Sulfur
 * 500mb Hydrogen Peroxide

Uses
Although it can be made into granular blocks for storage, it is recommended that it be made into Uranium Hexafluoride for processing in the Gas Centrifuge.

Trivia

 * In real life, yellowcake is not necessarily yellow, in modern times, it is usually brown or black. The yellow in its name comes from early mining processes.
 * Despite this, yellowcake can be produced using peroxide and sulfur, so the in-game process of production is still accurate.
