Coordinates: 53.36°N 0.81°W. 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 ...
Fusion power. 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.
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.
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.
Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. When a fissile nucleus like uranium-235 or plutonium-239 absorbs a neutron, it splits into lighter nuclei, releasing energy, gamma radiation, and free neutrons, which can induce further fission in a self-sustaining chain reaction.
The nuclear fuel cycle, also called nuclear fuel chain, is the progression of nuclear fuel through a series of differing stages. It consists of steps in the front end, which are the preparation of the fuel, steps in the service period in which the fuel is used during reactor operation, and steps in the back end, which are necessary to safely ...
According to the simulation, a 70 Mega Amp Z-pinch facility in combination with a Laser may be able to produce a spectacular energy return of 1000 times the expended energy. A 60 MA facility would produce a 100x yield. [24] JET announces a major breakthrough in controlling instabilities in a fusion plasma. One step closer to controlling nuclear ...
