Glossary

Actinides

All elements including and beyond actinium (Z > 89) in the periodic table. In spent fuel, the major actinides of interest are uranium, plutonium, neptunium, americium, and curium.

Cathode processor

A high-temperature vacuum distillation furnace used to separate salt from metallic actinides deposited on an electrorefiner cathode.

Centrifugal contactors

Liquid-liquid extraction equipment used for aqueous solvent extraction that consists of a spinning rotor to intensely mix the different phases.

Ceramic waste

The glass-bonded sodalite matrix used to encapsulate waste salt from electrorefiner operation.

COEX™

French process for coextracting uranium and plutonium using extraction methods similar to PUREX.

Electrorefiner

An electrochemical system used to separate actinides from spent fuel using a molten salt electrolyte.

Experimental Breeder Reactor-II

A sodium-cooled, fast test reactor operational at Argonne National Laboratory-West from 1963 to 1994.
