Watch next. Kirk Sorensen shows us the liquid fuel thorium reactor -- a way to produce energy that is safer, cleaner and more efficient than current nuclear power.

MSRs fall into two classes: salt-cooled reactors, in which the core contains a solid fuel and liquid salt coolant, and salt-fueled reactors, in which the fuel is dissolved within the salt. The term "fluoride salt-cooled high-temperature reactor" (FHR) was adopted in 2010 to distinguish fluoride salt-cooled MSRs from other MSRs.

The Liquid Fluoride Thorium Reactor is a type of Molten Salt Reactor.

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.

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 …

3.2. NaF-ZrF 4 (Nafzirf) The candidate primary coolant for a Fluoride-salt-cooled High-temperature Test Reactor (FHTR) is nafzirf, a sodium zirconium fluoride salt with a 59.5–40.5 mol% composition of NaF and ZrF 4, respectively. The melting temperature is 500 °C, and it boils at over 1350 °C.

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 …

The idea of a liquid-fuel nuclear reac tor is not new. Enrico Fermi, creator in 1942 of the first nuclear reactor in a pile of graphite and uranium blocks at the University of Chicago, started. up the world's first liquid-fuel reac. tor two years later in 1944, using ura. nium sulfate fuel dissolved in water.

VIEWPOINT. According to the U.S. Geological Survey in 2009, the U.S. proven thorium reserves are approximately 440,000 tons, enough to last for hundreds of years at full-scale LFTR implementation. And it is estimated that the worldwide proven reserves are 1.3 million tons, excluding China. LFTRs use only one ton of thorium per year for a 1000 ...

Molten salt reactors. By Dr. Nick Touran, Ph.D., P.E.,, Reading time: 19 minutes. Molten Salt Reactors (MSRs) are nuclear reactors that use a fluid fuel in the form of very hot fluoride or chloride salt rather than the solid fuel used in most reactors. Since the fuel salt is liquid, it can be both the fuel (producing the heat) and the coolant ...

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).

In January 2011, CAS launched a CNY3 billion (USD444 million) R&D programme on liquid fluoride thorium reactors (LFTRs), known there as the thorium-breeding molten-salt reactor (Th-MSR or TMSR), and claimed to have the world's largest national effort on it, hoping to obtain full intellectual property rights on the technology.
