Measurement of process parameters in reactive metals processing, such as actinides, is extremely difficult due to dynamic nature of system operating at high temperatures and under protective atmospheres. In addition, performing studies with radioactive strategic metals is, generally, prohibitively expensive with significant safety concerns. This study discusses the use of cerium metal to simulate the pyrometallurgical characteristics of plutonium. Design parameters relating to ceramic component arrangement, process parameters relating to electrolyte behavior and operating parameters relating to cell temperature, anode stirring speed, current density and back emf for electrorefining have been studied. Molten tin, gallium, iodine and antimony-cadmium alloy have also been used to study the different parameters involved. Validity and justification of these measurements has been discussed.
