Some of the following points can be valid for one reactor design and another point can be invalid for another thorium-based reactor. Therefore, be careful when you argue for or against thorium reactors. Possible Advantages Get price

Thorium fuel cycle

The thorium fuel cycle is a nuclear fuel cycle that uses an isotope of thorium, 232 Th, as the fertile material.In the reactor, 232 Th is transmuted into the fissile artificial uranium isotope 233 U which is the nuclear fuel.Unlike natural uranium, natural thorium contains only trace amounts of fissile material (such as 231 Th), which are insufficient to initiate a nuclear chain reaction.

The First Thorium Salt Reactors in Over 40 Years Were Just

Aug 25, 2017Molten salt reactors use fluoride salts under low pressures as a coolant for the nuclear reaction. Dissolving the thorium salts into this molten liquid and irradiating it with neutrons to kick off the transmutation is one way to extract energy from the process. Get price

Advantages of liquid fluoride thorium reactor in

Apr 29, 2015Liquid Fluoride Thorium Reactor (LFTR) is an innovative design for the thermal breeder reactor that has important potential benefits over the traditional reactor design. LFTR is fluoride based liquid fuel, that use the thorium dissolved in salt mixture of lithium fluoride and beryllium fluoride. Therefore, LFTR technology is fundamentally different from the solid fuel technology currently in use. Get price

LFTR Advantages

Thorium is much more abundant than Uranium, and is significantly cheaper due to the abundance. Thorium is usually thrown away during the process of mining rare-earth metals. Gram per gram, thorium is much more efficient than uranium, as around 99% of it is used in the reaction.[1] Get price

Liquid Flouride Thorium Nuclear Reactors Mentioned by

Dec 22, 2019The Liquid Fluoride Thorium Reactor is a type of Molten Salt Reactor. Molten Salt Reactors are Generation IV nuclear fission reactors that usage molten salt as either the primary reactor coolant or as the fuel itself; they trace their origin to a series of experiments directed by Alvin Weinberg at Oak Ridge National Laboratory in the '50s and '60s.

LFTR

The Liquid Fluoride Thorium Reactor, or LFTR (pronounced lifter) in short, is the first reactor in history to have its own internet based fan club.

Thorium

Thorium-fueled molten salt reactors are often referred to as Liquid Fluoride Thorium Reactors (LFTR). Thorium does have its advantages in an MSR though. MSRs can process decay products due to their use of fluids rather than solid fuels. This is useful because when Thorium-232 absorbs a neutron it beta decays to Proactinium-233, which has a half Get price

Thorium Myth vs Facts – AIM Truth Bits

Apr 20, 2018Misrepresentation: Thorium reactors still need uranium or plutonium. This is a proliferation risk. This is a misrepresentation of how a liquid-fluoride thorium reactor (LFTR) operates. It is true that any reactor, including a LFTR, needs fissile material in order to start up. Get price

Thorium can thus be burned in a conventional reactor along with enriched uranium or plutonium to provide the necessary neutrons.

Thorium Reactor

Reactors containing molten thorium salt are called liquid fluoride thorium reactors (LFTR). In general, use of thorium-based fuel in light water reactors is possible, but not so promising. BWR fuel assemblies can be flexibly designed in terms of rods with varying compositions (fissile content), and structural features enabling the fuel to experience more or less moderation (e.g. half-length fuel rods).
