Abstract Scope |
Molten fluoride salts are finding growing applications as fuel solvents and heat transfer fluids for molten salt reactors (MSRs), as thermal storage media, and in molten salt electrolysis for material recovery. These salts have been less explored than chloride or nitrate systems due to their high melting points and reactivity with crucibles. As part of the University of South Carolina’s task to develop the Molten Salt Thermal Properties Database-Thermochemical (MSTDB-TC), an open-source compendium serving as a key-resource for MSRs, significant effort has been expended on understanding and performing measurements on salts. Of the several thermochemical parameters examined, determining heat capacity is the most challenging, requiring extensive experimental work to obtain sufficiently accurate values. This presentation will explore the suitability of well-established methods for measuring heat capacity of salts, comparing the use of multiple calorimeters. The experimental procedures will be thoroughly detailed, identifying the practicalities involved in obtaining accurate measurements. |
