| Abstract Scope |
To develop molten salt reactors, the knowledge of thermophysical properties, such as density, is important to validate physical models used to design and enhance reactor performances. However, mixtures used are often insufficiently documented and their ideal behavior is assumed. Consequently, a technique for determining the density of molten salts was developed using X-ray transmission imaging, enabling the measurement of salt mixtures densities at different temperatures and compositions. To determine their density, being the ratio of mass to volume, salts are weighted before heating, and their volumes are calculated using image processing. The experimental method was validated on well-known pure alkali chloride salts by comparing the experimental densities with those obtained from the bibliography. Then, binary mixtures of salts were investigated: molar volume variation as a function of the composition revealed volume expansions or contractions due to interactions between the molecules, related to the chloroacidity. |
