摘要

Predominance phase diagrams for metal-molten salt systems are diagrams of potential vs. the negative2- 2- logarithm of the activity of O ions (E-pO ); they are a valuable tool for predicting and understandingelectrochemical systems and for optimising process conditions. Here, predominance diagrams areproduced for the range of nuclear spent materials (U, Pu, Np, Am, Cm, Cs, Nd, Sm, Eu, Gd, Mo, Tc,Ru, Rh, Ag and Cd species), in both LiCl-KCl at 500 C and NaCl-KCl at 750 C. The two salteutectics were chosen as they are the two main systems used for pyroprocessing; temperatures wereselected within each salts normal operating range. All of the diagrams presented show regions ofstability for the different metal species, their oxides and chlorides at unit activity; however, thisactivity can be altered in accordance with the equations derived. Examples of selective electrochemicalreduction are also demonstrated for potential spent fuel reprocessing in both salt systems.
