FLiBe is a molten salt made from a mixture of lithium fluoride (LiF) and beryllium fluoride (BeF 2). It is both a nuclear reactor coolant and solvent for fertile or fissile material. It served both purposes in the Molten-Salt Reactor Experiment (MSRE) at the Oak Ridge National Laboratory .
The liquid fluoride thorium reactor (LFTR; often pronounced lifter) is a type of molten salt reactor. LFTRs use the thorium fuel cycle with a fluoride -based molten (liquid) salt for fuel. In a typical design, the liquid is pumped between a critical core and an external heat exchanger where the heat is transferred to a nonradioactive secondary ...
Kirk Sorensen, former NASA scientist and chief nuclear technologist at Teledyne Brown Engineering, is a long-time promoter of the thorium fuel cycle, coining the term liquid fluoride thorium reactor. In 2011, Sorensen founded Flibe Energy, [38] a company aimed at developing 20–50 MW LFTR reactor designs to power military bases. (It is easier ...
In a cell adjacent to the reactor was a simple facility for bubbling gas through the fuel or flush salt: H 2-hydrogen fluoride mixture, in roughly 10:1 ratio, to remove oxide, fluorine to remove uranium as uranium hexafluoride. [4] [5] [6] Molten FLiBe. The secondary coolant was LiF-BeF 2 (66–34 mole %).
Lithium fluoride (highly enriched in the common isotope lithium-7) forms the basic constituent of the preferred fluoride salt mixture used in liquid-fluoride nuclear reactors. Typically lithium fluoride is mixed with beryllium fluoride to form a base solvent ( FLiBe ), into which fluorides of uranium and thorium are introduced.
Fluoride is a mineral that occurs naturally in water, soil and air that has been demonstrated to prevent dental cavities, or tooth decay. It works by strengthening the tooth's enamel, its hard ...
Fluoride salts, like all salts, cause corrosion in most metals and alloys. FLiNaK is different from FLiBe in the sense that is a basic melt—or it has an excess of fluorine ions. As FLiNaK melts, all three components are alkali fluorides and therefore disassociate into positive and negative ions.
