Binding Preferences Predictions Across the Actinide Series

Predictive capabilities for binding preferences of lanthanides is heavily restricted by computational cost. A model lanthanide nitrate system was utilized to develop computational cost­reducing methods across the lanthanide series to be applied to optimization of separations in processes relevant to critical materials and nuclear forensics.

Science Achievement       

Researchers from the Institute for Nuclear Security and Radiochemistry Center of Excellence at the University of Tennessee, University of North Texas, U.S. Army Nuclear and Countering Weapons of Mass Destruction Agency, Stony Brook University, Brookhaven National Laboratory, and Y-12 National Security Complex evaluated method dependence in binding preferences across the actinide series. NERSC supercomputers allowed for accurate targets to be established – essential to evaluate less expensive methods to be applied in binding of elements of interest in nuclear security and fundamental research of lesser-known actinide compounds.

Impact

Fundamental understanding of actinide-containing compounds is essential for nuclear security. Traditional experimental evaluation of many actinide-containing compounds is restricted to expert facilities due to the high radioactivity of these elements. Short half-lives also limit experimental capability of later actinides which still require in-depth understanding of their properties.

Research Details

These researchers developed a systematic in-depth study to evaluate commonly used methods including high levels of theory and relativistic effects seeking to establish efficient practices to be applied to actinide studies across disciplines.
