Abstract

The liquid cadmium cathode is a pyroprocessing technology used for the recovery of group actinide metals from the molten chloride salts that support uranium electrorefining. This article presents a model for the performance of a liquid cadmium cathode based on considerations of salt/alloy equilibrium thermodynamics, Cd-U-Pu phase diagram behaviors, and mass balance constraints. In conclusion, the model demonstrates how the salt/cadmium system responds as incremental additions of uranium are made to the liquid cadmium cathode.

Analysis and modeling of the equilibrium behaviors of U and Pu in molten LiCl-KCl/Cd system at 500 °C

Journal Article Fredrickson, Guy L. ; Yoo, Tae-Sic - Journal of Nuclear Materials

In the field of pyroprocessing of used nuclear fuels, liquid cadmium is applied in different ways to recover transuranics from molten salt, while effecting some degree of separations between transuranics and lanthanides. In this work, a model of the separation performance between uranium and plutonium across the phase boundary between molten salt and liquid cadmium is presented. The salt is the LiCl-KCl eutectic with solute concentrations of UCl₃ and PuCl₃. The cadmium is the liquid cadmium phase field from the Cd-U-Pu ternary alloy system. Lastly, the model used to describe the behavior of uranium and plutonium in the salt/cadmium systemmore »« less

Simpson Pyroprocessing Technology Department Idaho National Laboratory P.O. Box 1625, Idaho Falls, ID 83415 USA Abstract - A series of six bench-scale liquid cadmium cathode (LCC) tests was performed to obtain basic separation data with focus on the behavior of rare earth elements. The electrolyte used for the tests was a mixed salt from the Mk-IV and Mk-V electrorefiners, in which spent metal fuels from Experimental Breeder Reactor-II (EBR-II) had been processed.

Experimental observations on electrorefining spent nuclear fuel in molten LiCl-KCl/liquid cadmium system.

Conference Johnson, T A ; Laug, D V ; Li, S X ; ...

Argonne National Laboratory (ANL) is currently performing a demonstration program for the Department of Energy (DOE) which processes spent nuclear fuel from the Experimental Breeder Reactor (EBR-II). One of the key steps in this demonstration program is electrorefining of the spent fuel in a molten LiCl-KCl/liquid cadmium system using a pilot scale electrorefiner (Mk-IV ER). This article summarizes experimental observations and engineering aspects for electrorefining spent fuel in the molten LiCl-KCl/liquid cadmium system. It was found that the liquid cadmium pool acted as an intermediate electrode during the electrorefining process in the ER. The cadmium level was gradually decreased duemore »« less

Thermodynamic properties of U, Np, Pu, and Am in molten LiCl-KCl eutectic and liquid cadmium

Journal Article Roy, J J ; Grantham, L F ; Grimmett, D L ; ... - Journal of the Electrochemical Society

Thermodynamic property measurements for actinides in the LiCl-KCl/Cd system have been obtained as part of the development of an electrochemical pyropartitioning process to remove actinides from PUREX waste residues. Electrochemical potential measurements and distribution ratios were employed to obtain standard Gibbs free energies of formation for actinide chlorides in LiCl-KCl, activity coefficients of reduced actinides in Cd, and distribution coefficients for actinides in the LiCl-KCl/Cd system relative to neodymium. The temperature-dependent free energies of formation for U, Np, and Pu were {Delta}G{degree}{sub UCl{sub 3}} = {minus}844.2 + 0.1681T (kJ/mol), {Delta}G{degree}{sub NpCl{sub 3}} = {minus}902.9 + 0.1688T (kJ/mol), and {Delta}G{degree}{sub PuCl{submore »« less

Monitoring of Actinide Concentrations in Molten LiCl-KCl Salt using Alpha Spectroscopy: Final Progress Report

Technical Report Cao, Lei R. ; Blue, Thomas E. ; Simpson, Michael F. ; ...

This project addresses the need for real time monitoring of actinide concentrations for spent fuel reprocessing utilizing alpha spectroscopy. This project specifically focuses on spent fuel reprocessing with the pyroprocessing technique that uses high temperature molten salt. Pyroprocessing uses molten salt such as lithium chloride and potassium chloride to separate out uranium and plutonium from spent fuel. To prevent any possible diversion of high purity plutonium in this process, monitoring of the actinide concentrations within the refinery are essential for safeguards and non-proliferation efforts. Alpha spectroscopy enables the identification and quantification of actinide isotopic concentrations. However, current assay methods involvingmore »« less
