| Abstract Scope |
Molten Salt Reactors (MSR) are leading candidates among the Generation IV advanced nuclear power reactor designs considered for development in the US. In our work, we utilize multi-modal approaches to study the local structure evolution of metal solutes as well as corrosion at metal-salt interfaces in molten salt environments. We utilize a combination of synchrotron techniques such as x-ray absorption spectroscopy in combination with lab-based ultra-violet spectroscopy and electron microscopy to monitor local and bulk structure evolution of metal solutes and corrosion in molten salt systems. Ab initio molecular dynamics (AIMD) simulations are utilized to complement experimental methods to quantify the populations of different coordination states of ions with highly disordered coordination environments. The evolution of local structure and metal-salt interface as function of salt composition and temperature is discussed. |
