You can craft Stable Flux, which acts as Pure Cobalt Flux, from the raw flux that you can find from plants inside Blast Zones, which are the areas that a nuke has recently hit.

​​​​​​You can collect flux from plants in a Blast Zone regardless of who launched the nuke, so it may be easier to wait for somebody else to launch a nuke to collect flux instead of launching a nuke yourself.

If you want to launch a nuke, then you’ll need to join and reach General rank in the Enclave, gather eight Nuke Codes, obtain a Nuclear Launch Keycard by defeating a Cargobot, and enter a Missile Silo, which is the location where you can launch the nuclear weapon.

There are multiple types of flux, including Raw Cobalt Flux, Raw Fluorescent Flux, Raw Yellowcake Flux, Raw Violet Flux, and Raw Crimson Flux. You can use each of these items to craft Pure Cobalt Flux; however, you need ten to craft one Pure Cobalt Flux.

You can’t mix and match the types. You need to have ten Raw Violet Flux, for example.

The plants that can grant you these types of flux include the following.

Snaptail

Firecap
