Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

ARPA-E announces $40 million to develop transmutation technologies for UNF
The Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) announced $40 million in funding to develop cutting-edge technologies to enable the transmutation of used nuclear fuel into less-radioactive substances. According to ARPA-E, the new initiative addresses one of the agency’s core goals as outlined by Congress: to provide transformative solutions to improve the management, cleanup, and disposal of radioactive waste and spent nuclear fuel.

Cyclic voltammetry is one of the most common electroanalytical methods for determining the thermodynamic and electrochemical behavior of a species in the eutectic molten salt. The diffusion coefficient, apparent standard potential, transfer coefficient, equilibrium potential, and other parameters can be determined through this method. This study focused on a development of an interactive reverseengineering method by analyzing available uranium chloride data sets (1 to 10 wt%) in a LiCl-KCl molten salt at 773 K under different scan rates to help improve and provide robustness in detection analysis. A principle method and a computational code have been developed by using electrochemical fundamentals and coupling various variables, such as the diffusion coefficients, formal potentials, and process time duration. In addition, a graphical user interface (GUI) through the commercial software Matlab was created to provide a controllable environment for different users. Results provide plots of current, potential, and concentration of each species as a function of time under various determined conditions. The GUI also displays the reversible and irreversible peaks, in a very short run time (around 2 min), with an adequately selected time interval of approximately 0.08 s and an ability to calculate the concentration of each species (e.g., U4+ and U3+) at any specified conditions.
