Yellowcake

Yellowcake is a type of concentrated uranium compound, primarily uranium oxide (U₃O₈), produced during the initial stage of nuclear fuel processing. It is a yellowish powder that results from refining uranium ore to remove impurities. This material serves as the raw feed for further enrichment processes to increase the concentration of uranium-235, which is necessary for nuclear power plants or weapons. Yellowcake itself is not radioactive enough to be dangerous, but it contains uranium, which requires careful handling and regulation due to its potential use in energy production or proliferation.
