Thorium is a rarely used nuclear fuel that occurs solidly under normal conditions. It is traditionally found in trace levels in soil, rocks, and water. Thorium is estimated to be 3x more abundant than Uranium in Earth's crust. It exists naturally as Thorium 232 (which is the form needed for nuclear reactions).

Function & Usage. Thorium Fuel Rods can be used in a Nuclear Reactor to provide power, or as ammunition for the Rapid Fissile Accelerator. The condition of the fuel rod drains as it is used, and when it reaches 0% it no longer produces power. Empty fuel rods can be refilled with more Thorium, or recycled into Depleted Fuel .
Abstract. The review reveals that experience in the reprocessing of irradiated thorium materials is limited. Plants that have processed thorium-based fuels were not optimized for the operations. Previous demonstrations of several viable flowsheets provide a sound technological base for the development of optimum reprocessing methods and facilities.

The development of safeguards approaches for thorium-based fuel cycles is therefore a matter of some urgency. Yet, the focus of the international safeguards community remains mainly on safeguarding conventional 235 U- and 239 Pu-based fuel cycles while the safeguards challenges of thorium-uranium fuel cycles remain largely …

Radionuclide Basics: Thorium. Thorium (chemical symbol Th) is a naturally occurring radioactive metal found at trace levels in soil, rocks, water, plants and animals. Thorium is solid under normal conditions. There are natural and man-made forms of thorium, all of which are radioactive. In general, naturally occurring thorium exists as Th …
From Eq. (2), 232 U is more of a contaminant to 233 U in the reaction chain of thorium fuel cycle, and therefore, makes it difficult to separate fissile 233 U because of its radiation hazard [8]. This contaminant decays to emit high energy gamma radiation isotopes (for example Tl-208) that will require the use of remote handling equipment to ...

the development of THOREX process. There are two options for use of thorium in the PWRs. The first option, called heterogeneous approach, assumes using the mixture of thorium and uranium oxides within each fuel rod. The second one considers placing thorium and uranium fuel in separated regions, called the blanket and the seed, …

Thorium fuel is the cheapest fuel to make, even cheaper than Uranium Fuel, as it can be bred directly from Thorium-232. It runs cooler than the other fuels, this means it produces less energy but is safer to run overall. After its fuel cycle and recycling, it makes more fissile material than it consumed. It is made either by mixing 2 Thorium (Th-232) and 1 U-233 …
