A study done on uranium morphology and speciation via chemical separations and spectroelectrochemical techniques during pyroprocessing is necessary and beneficial in determining the sources and causes of the impurities stated above. In doing so, methods and technologies can be developed in order to produce higher purity products with pyroprocessing achievable, increasing the efficiency of the nuclear fuel cycle. This increase in efficiency will cause a decrease in purchase costs of natural uranium and avoidance of disposal costs for large volume of spent fuel, which supports the Department of Energy Office of Nuclear Energy (DOE-NE) mission’s research objective to develop sustainable fuel cycle.

The study focuses on fundamental electrochemical properties of alkali/alkaline earth fission products and possible actinide elements in LiCl-KCl molten salts with liquid metal electrodes in a controlled glovebox environment, for possible improvement on reprocessing technology applications.

Michael Woods, Postdoc at INL

The study focuses on determining the material compositions and characteristics of unknown materials by creating a database of information using measurements from a quasi-simultaneous system utilizing different voltammetric methods (e.g., cyclic voltammetry (CV), chronopotentiometry (CP), etc.) and laser-induced breakdown spectroscopy (LIBS).

Hunter Andrews, Postdoc at ORNL

This study focuses on different techniques for measuring physical properties of molten salt such as density and viscosity.

Reginald Jones, Graduated with M.S. Degree

The study focuses on assessment on the RSC and its usage in capturing certain elements (fission products or radioactive materials) within its structure and development of a detection method for radioactive elements captured in ceramic materials.
