| Abstract Scope |
Understanding the effect of radiolysis on salt integrity and the evolution of gases is of importance to the storage of irradiated solid salts, the prediction of salt deposition and aerosol behavior in a molten salt reactor off-gas system, and potentially to the performance of salt while in core. We investigated the effect of neutron irradiation in chloride-bearing molten salts (UCl<sub>3</sub>, NaCl, and KCl mixtures) by comparing densities measured before and after irradiation at the Massachusetts Institute of Technology Reactor. Densities were measured by neutron radiography at the US DOE Office of Science MARS instrument at the High Flux Isotope Reactor at Oak Ridge National Laboratory. Our findings suggest that the complex physical and chemical behavior of molten chloride salts could be affected by irradiation. Thus, radiation-induced changes in thermophysical properties, especially wetting behavior of salts, merit further investigation. |
