| Abstract Scope |
Molten salts are proposed as liquid fuels or coolants in a new fleet of nuclear reactors. The salt will be exposed to high radiation levels under those conditions; thus understanding the chemical effects of radiolysis on the molten salt fuel is essential to reliable reactor operation. Building this understanding begins with characterizing the speciation of primary salt radiolysis products (solvated electrons (esolv–) and Cl2–) in different molten salt compositions and measuring their reaction kinetics with metal ions, which depend strongly on the composition of the salt. We do this by performing high-temperature pulse radiolysis transient absorption spectroscopy at the BNL Laser-Electron Accelerator Facility, aided by insights from ab initio molecular dynamics simulations. This work was supported as part of the Molten Salts in Extreme Environments Energy Frontier Research Center funded by the U.S. Department of Energy, Office of Science. |
