(385g) Development of Neutron Measurements for in-Situ Interface Corrosion Kinetics and Salt Properties

The main goal of the study is to understand the corrosion and chemical properties of molten salts and then to provide fundamental data for material selection including the molten salt systems for both nuclear and solar applications.

The presentation will focus on the development of in-situ neutron techniques for fundamental understanding of the mechanisms of molten salt corrosion, and the micro-structural response of containment alloys thereto, to measure the surface corrosion kinetics. We are working on realization and initial application of in-situ techniques for measuring molten salt fundamental properties including molten salt structure, dynamics, and salt density, etc. and the micro-structural and -chemical response of containment alloys to corrosive molten salt environments. The two neutron techniques involved are Vibrational Spectroscopy and Neutron Reflectometry. They both have unique characteristics for complex liquids at high temperatures. Moreover, while we are designing and manufacturing sample environments for harsh environments (high temperature and corrosive), they will provide great first-of-the-kind experimental data for molten salt systems.
