Spherical Tokamak for Energy Production (STEP) is a spherical tokamak fusion plant concept proposed by the United Kingdom Atomic Energy Authority (UKAEA) and funded by the UK government. [ 1 ] [ 2 ] [ 3 ] The project is a proposed DEMO -class successor device to the ITER tokamak proof-of-concept of a fusion plant, the most advanced tokamak ...
Deuterium–tritium fusion (sometimes abbreviated D+T) (DTF) is a type of nuclear fusion in which one deuterium (2 H) nucleus (deuteron) fuses with one tritium (3 H) nucleus (triton), giving one helium-4 nucleus, one free neutron, and 17.6 MeV of total energy coming from both the neutron and helium. It is the best known fusion reaction for ...
t. e. Nuclear fusion is a reaction in which two or more atomic nuclei, usually deuterium and tritium (hydrogen isotopes), combine to form one or more different atomic nuclei and subatomic particles (neutrons or protons). The difference in mass between the reactants and products is manifested as either the release or absorption of energy.
Nuclear fuel has the highest energy density of all practical fuel sources. The processes involved in mining, refining, purifying, using, and disposing of nuclear fuel are collectively known as the nuclear fuel cycle. Most nuclear fuels contain heavy fissile actinide elements that are capable of undergoing and sustaining nuclear fission.
1932. Ernest Rutherford 's Cavendish Laboratory at Cambridge University begins nuclear experiments with a particle accelerator built by John Cockcroft and Ernest Walton. [4] In April, Walton produces the first man-made fission by using protons from the accelerator to split lithium into alpha particles.
Levelized cost of energy (LCOE) for various sources of energy including wind, solar and nuclear energy [175] Some economists suggest fusion power is unlikely to match other renewable energy costs. [174] Fusion plants are expected to face large start up and capital costs. Moreover, operation and maintenance are likely to be costly. [174]
The liquid fluoride thorium reactor (LFTR; often pronounced lifter) 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 ...
Date (s) of construction. 2013–2034. ITER (initially the International Thermonuclear Experimental Reactor, iter meaning "the way" or "the path" in Latin [ 2 ][ 3 ][ 4 ]) is an international nuclear fusion research and engineering megaproject aimed at creating energy through a fusion process similar to that of the Sun.
