| Abstract Scope |
Molten salts, like other matter, are ionized upon irradiation and transient reactive species are generated. Steady-state and pulse radiolysis techniques have been to understand the radiation-induced chemistry of molten chloride salt systems and develop a predictive radiation chemical kinetics model. The LEAF picosecond pulse radiolysis facility has been used to observe the polyhalide ions, Cl2- and Cl3-, in molten ZnCl2. The transients are long-lived and likely to react even with dilute solutes. A series of studies of increasing complexity have been initiated to understand the primary species produced in the radiolysis of pure molten chloride salts and then measure their reactivity with the most important solutes expected in molten salt reactors. These experiments will be complemented by steady-state gamma and He ion radiolysis. Coupling steady-state measurements and time-resolved reaction kinetics will allow for the deployment of multi-scale modeling methodologies for these systems, providing quantitative mechanistic insight and predictive capabilities. |
