Molten salts in fusion nuclear technology

In the field of fusion nuclear technology, much interest lies in the use of molten salts. In some innovative design studies, the use of molten fluoride, especially the LiF–BeF2 mixture called Flibe, has been suggested as the primary loop coolant because of its inherent advantages such as high temperature stability and low electrical conductivity. The use of molten salts has also been suggested for the chemical processing of tritium. Together with the physical and chemical properties of molten salts, recent studies on the use of molten salts in fusion nuclear technology are reviewed and discussed, and issues are addressed for successful future development.
