The thorium cycle is a nuclear fuel cycle that utilizes thorium-232 as a fertile material to breed uranium-233, which can then be used as nuclear fuel. It offers the potential for safer, more abundant, and less wasteful nuclear energy compared to the traditional uranium-plutonium cycle.

Thorium Cycle

The nuclear fuel cycle is a series of industrial processes that involve the production, use, and management of nuclear fuel for energy generation and other applications. It encompasses the entire journey from uranium mining to waste disposal, with the potential for recycling and reprocessing to extend the fuel's usability and reduce waste.

Nuclear Fuel Cycle

Thorium-232 is a naturally occurring, fertile isotope of thorium that can be converted into the fissile isotope uranium-233 through neutron absorption and subsequent beta decay, making it a potential fuel for nuclear reactors. Its abundance and potential for producing less long-lived radioactive waste compared to uranium and plutonium make it an attractive option for sustainable nuclear energy production.

Thorium-232

Fertile material refers to substances that are not themselves capable of sustaining a nuclear chain reaction but can be converted into fissile material through nuclear reactions, such as neutron absorption. These materials are crucial for breeding processes in nuclear reactors, allowing for the production of more fissile material and enhancing the efficiency and sustainability of nuclear power generation.

Fertile Material

Uranium-233 is a fissile isotope of uranium that can be bred from thorium-232 in a nuclear reactor, making it a potential fuel for thorium-based nuclear power. It has a half-life of 159,200 years and can sustain a nuclear chain reaction, but its production and use are complicated by the presence of highly radioactive contaminants and proliferation concerns.

Uranium-233

Nuclear fuel is a material used in nuclear reactors to sustain a nuclear chain reaction, primarily composed of isotopes like Uranium-235 or Plutonium-239. The efficiency and energy output of nuclear fuel are determined by its enrichment level and the reactor design in which it is used.
