New Test Method for Measurement of Viscosity of a Molten Salt using a Rotational Viscometer
1. Scope
Method will be used to determine the viscosity of a molten salt (Pa s), including salt mixtures, contaminated salts, and radioactive salts, at high temperatures (e.g., 900 °C) in a controlled atmosphere by using a rotational viscometer. The torque generated by the resistance of a spindle rotated at a constant rotational speed due to resistance of the salt is measured. Controls necessary for accurate measurements are identified. These address the corrosive nature of molten salts, measurements of radioactive salts, elevated temperatures, and salt volatilization.
