The powerful magnet systems as well as heating and current drive diagnostic cryogenic cooling fuelling vacuum and power supply systems. Surrounding the central reaction chamber are all of the systems that will work in concert to create a 150 million degree plasma. The 23 000 tonne iter tokamak is a complex assembly of one million components and an estimated ten million individual parts.
Located in provence the international. The world s largest nuclear fusion project that will replicate reactions in the sun to create the ultimate clean energy source has begun assembly in france. A nuclear reactor formerly known as an atomic pile is a device used to initiate and control a self sustained nuclear chain reaction nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion heat from nuclear fission is passed to a working fluid water or gas which in turn runs through steam turbines.
Nuclear fusion is a reaction in which two or more atomic nuclei are combined 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 this difference in mass arises due to the difference in atomic binding energy between the atomic nuclei. Fusion in contrast occurs when two or more smaller atoms fuse together creating a larger heavier atom. In fission an atom is split into two or more smaller lighter atoms.
Nuclear fusion and nuclear fission are different types of reactions that release energy due to the presence of high powered atomic bonds between particles found within a nucleus. Since the 1930s scientists have known that the sun and other stars generate their energy by nuclear fusion. The use of nuclear fusion reactions for electricity generation remains theoretical.
Fusion reactor also called fusion power plant or thermonuclear reactor a device to produce electrical power from the energy released in a nuclear fusion reaction. Experiments the international thermonuclear experimental reactor will be based. It sounds futuristic and.
That s the difference nuclear fusion. Nuclear reactors diagram. Eager scientists have pursued the harnessing of nuclear fusion s power generating capacity for almost three quarters of a century the uk atomic energy authority patented a fusion reactor in 1946 but without reliable success.
Or so goes the theory.
Nuclear fusion reactor diagram. The fusion reactor will heat a stream of deuterium and tritium fuel to form high temperature plasma. It will squeeze the plasma so that fusion can take place. The power needed to start the fusion reaction will be about 70 megawatts but the power yield from the reaction will be about 500 megawatts. Jonny nelson introduces an animated explanation of fission and fusion nuclear fission is the splitting of a large atomic nucleus into smaller nuclei.
In a nuclear reactor a neutron is absorbed.
