Pure yellowcake flux (Fallout 76)

Pure yellowcake flux is a component in Fallout 76.

Characteristics
While processing it renders it impossible to consume, it does turn it into a vital crafting component, used in a variety of high level crafting recipes, including: high level casual underarmor linings decontamination showers, fusion cores, core assemblies, Tesla bracers, and tesla coils for power armor, as well as the Electrically Charged, Grounded, and Speed Demon serums.

Locations

 * Raw flux can be harvested from plants in nuked zones (see above) and processed into stable (or pure) flux.
