Y-12 achieves technology milestone in purifying uranium ...
Nov 30, 2020 · Uranium is a critical material in Y-12’s Production operations. The “electrorefiner,” a piece of technology for recovering purified uranium metal from byproducts of the site’s manufacturing, uses an electrochemical processes in molten salts to purify the uranium metal. The end product is purified uranium crystals that are then melted in ...

Materials and Fuels Complex - Mark IV electrorefiner
The electrorefiner vessel contains a lithium chloride/potassium chloride (LiCl-KCl) eutectic molten salt electrolyte with a nominal concentration of uranium trichloride (UCl 3) that floats above a pool of molten cadmium. Chopped irradiated fuel segments are loaded in an anode basket and submerged in the molten salt electrolyte.

Electrorefining - an overview | ScienceDirect Topics
Two basic cell designs are used in silver electrorefining: the Balbach−Thum (horizontal) cell and the Moebius (vertical) cell (Figure 34.12).Common features of both cells include the anodes, cathodes, electrolyte, and separation of the anode in a bag to capture any insoluble material (usually gold and PGMs) released at the anode.
