Tritium Breeding Module
A tritium breeding module or TBM is a component of a fusion reactor that produces tritium. ITER will have four easily removable TBMs in order to test various material combinations in order to develop the breeding process.

Fusion Reactor
Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions. In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, while releasing energy. Devices designed to harness this energy are known as fusion reactors. Research into fusion reactors began in the 1940s, but as of 2025, no device has reached net power. Fusion processes require fuel, in a state of plasma, and a confined environment with sufficient temperature, pressure, and confinement time. The combination of these parameters that results in a power-producing system is known as the Lawson criterion. In stellar cores the most common fuel is the lightest isotope of hydrogen ( protium), and gravity provides the conditions needed for fusion energy production. Proposed fusion reactors would use the heavy hydrogen isotopes of deuterium and tritium for DT fusion, for which the Lawson criterion is the easiest to achieve. This produce ...

Tritium
Tritium () or hydrogen-3 (symbol T or H) is a rare and radioactive isotope of hydrogen with a half-life of ~12.33 years. The tritium nucleus (t, sometimes called a ''triton'') contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen-1 (''protium'') contains one proton and no neutrons, and that of non-radioactive hydrogen-2 ('' deuterium'') contains one proton and one neutron. Tritium is the heaviest particle-bound isotope of hydrogen. It is one of the few nuclides with a distinct name. The use of the name hydrogen-3, though more systematic, is much less common. Naturally occurring tritium is extremely rare on Earth. The atmosphere has only trace amounts, formed by the interaction of its gases with cosmic rays. It can be produced artificially by irradiation of lithium or lithium-bearing ceramic pebbles in a nuclear reactor and is a low-abundance byproduct in normal operations of nuclear reactors. Tritium is used as the energy source in radio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ITER
ITER (initially the International Thermonuclear Experimental Reactor, ''iter'' meaning "the way" or "the path" in Latin) is an international nuclear fusion research and engineering megaproject aimed at creating energy through a fusion process similar to that of the Sun. It is being built next to the Cadarache facility in southern France. Upon completion of the main reactor and first plasma, planned for 2033–2034, ITER will be the largest of more than 100 fusion reactors built since the 1950s, with six times the plasma volume of JT-60SA in Japan, the largest tokamak operating today. The long-term goal of fusion research is to generate electricity; ITER's stated purpose is scientific research, and technological demonstration of a large fusion reactor, without electricity generation. ITER's goals are to achieve enough fusion to produce 10 times as much thermal output power as thermal power absorbed by the plasma for short time periods; to demonstrate and test technologies that wo ...

Breeding Blanket
A breeding blanket is a device used in nuclear engineering to Nuclear transmutation, transmute quantities of an element, using the neutron flux from a fission reactor or fusion reactor. In the fission context, breeding blankets have been used since the 1950s in Breeder reactor, breeder reactors, to manufacture fission fuel from fertile material. In the fusion context, they have been conceptualized for the manufacture of tritium from lithium-6. In both scenarios, neutron radiation is converted into thermal energy in the blanket, leading it to require its own Cooling system (nuclear reactor), cooling system. Fission blanket Breeder reactor, Breeder reactors come in two types: thermal and fast. The former use thermal neutrons to activate thorium-232, ultimately producing uranium-233: + ^_n -> [\text\gamma\text] ->[\beta^-][\text] ->[\beta^-][\text] The latter use fast neutrons to activate uranium-238, ultimately producing plutonium-239: ^_U + ^_n -> ^_U ->[\beta^-][23.5\ \ce] ...
