The liquid fluoride thorium reactor 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 salt. The secondary salt then transfers its heat …

Typical compositions of base salts that have been used in liquid-fluoride reactors are 66 mole % LiF and 34 mole % BeF2. Post navigation. A Brief History of the Liquid-Fluoride Reactor.

Liquid-fluoride reactors are based upon the use of dissolved actinide fluoride salts in a carrier medium of low-absorption fluoride salt solvents. The most common formulations that have been considered and demonstrated for this mission are solvents based around low-melting point mixtures of beryllium fluoride (BeF2) and …

A LFTR is a type of molten salt reactor, significantly safer than a typical nuclear reactor. LFTRs use a combination of thorium (a common element widely found in the earth) and fluoride salts...

The World Nuclear Association says there are seven types of thorium reactor, but molten salt reactors using a liquid fluoride salt/thorium fuel-mix show the greatest promise for marine use. Liquid fluoride thorium reactors (LFTR) are fundamentally different from uranium reactors. Their liquid salt coolant allows higher operating …

Introduction. Molten salt reactors (MSRs) are liquid-fueled reactors that can be used for burning actinides, producing electricity, producing hydrogen, and producing fissile fuels (breeding). Fissile, fertile, and fission products are dissolved in a high-temperature, molten fluoride salt with a very high boiling temperature (∼1400 °C).

There is a viable option to replace current nuclear technology: Liquid Fluoride Thorium Reactors (LFTRs). LFTRs have distinct safety, environmental, and economic advantages over uranium-based and solid-fuel nuclear power. There are several pathways for using thorium and technical challenges which will not be fully covered here.
