| Abstract Scope |
Establishing an efficient and safe nuclear fuel cycle is one of the most critical challenges for the deployment of Molten Salt Reactors (MSRs). As MSRs operate, nuclear reactions generate new chemical species within the fuel salts. Developing a predictive understanding of the evolving chemical and physical properties of these multi-component solutions is essential for enabling advanced fuel-salt recycling technologies. The changing chemical composition affects the speciation and charge states of fission product ions. These changes directly influence the corrosivity of the salt, reactor performance, and the efficiency of fission product separation and actinide recovery.
We study molten chloride fuel salt containing fission products (Te, Zr, and Eu) in-situ using neutron scattering. Our experimental results are compared with high-fidelity ab initio and machine learning-based molecular dynamics simulations, providing a robust framework for understanding and predicting salt behavior under reactor-relevant conditions. |
