| Abstract Scope |
ORNL is deeply involved in advancing molten salt research. The Nuclear & Extreme Environment Measurements (NEEM) group helps in furthering technology readiness in two facets: thermophysical property determination and property database development. Currently, two property systems are employed with a third system under development. These include a rolling ball technique for viscosity and a variable gap apparatus for thermal conductivity, which have been used with both chloride and fluoride samples, including radioactive species. A surface tension system is under development employing the maximum bubble pressure technique. Results from these systems, as well as any available molten salt thermophysical property publications, are maintained in the Molten Salt Thermophysical Properties Database (MSTDB-TP), available through requested access. This presentation will describe the experimental systems with results, lessons, and future plans, along with an overview of data and efforts within the database. |
