This is a method of using lasers to create fusion. In the early 1960s, work began on inertial confinement fusion(ICF). This led to the International Thermonuclear Experimental Reactor (ITER) project, aimed at creating a sustainable energy source. The research found that these devices provide some of the best designs for confining plasma experiments. In 1953, Lev Artsimovich and Wolfgang Franz introduced Tokamaks and Stellarators to advance magnetic containment. Science began turning towards magnetic confinement technologies. They couldn’t make enough heat or pressure for a sustained nuclear reaction in labs. All these efforts turned out to be futile. Arthur Cavor’s suggestion was laser thermal compression of plasma fuel inside small shells. It later led to the development of atomic bombs during World War II.īy 1950, people had several ideas about how to create a lab-based fusion reaction. Enrico Fermi’s study on triggering “controlled” chain reactions inside uranium-containing material followed this discovery. In 1932, James Chadwick discovered the neutron and opened up new possibilities for nuclear physics research. Scientists developed theories about how atoms combine to release enormous amounts of energy. The history of nuclear fusion dates back to the early 20th century. To optimize efficiency, magnetic fields are used to contain the hot plasma while increasing its temperature. The process of nuclear fusion releases different forms of energy like photons and gamma rays from the core plasma. That’s because each proton carries an equal but opposite charge upon fusion. These help faster particle movement, increasing the chances that atoms will collide to form heavier nuclei.įusing two or more nuclei sounds difficult, and it is! You have to reach high temperatures and pressure - extremes even! But when you do this, you’re using the strong reaction forces between the positively charged nuclei to create a single nucleus with less mass. The conditions for nuclear fusion are high temperature and pressure. This energy is then used to power fusion-based reactions. This requires a lot of energy and pressure - on the order of millions of degrees Celsius! That amount of heat and pressure is usually found in stellar bodies such as stars.Īs two nuclei combine, they release a large amount of energy. At the same time, they generate a force called a nuclear force to bind them together. When two atoms come close together, their positive nuclear cores repel each other. It’s different from nuclear fission which also creates energy but results in radioactive waste. Nuclear fusion is when two or more atomic nuclei join forces to form a heavier nucleus, releasing an enormous amount of energy in the process. This energy can be harvested as heat for propulsion or electricity generation purposes. In the reaction, some of the mass from the nuclei converts into energy as per Albert Einstein’s well-known equation E=mc². Nuclear fusion is a process where two light atomic nuclei, typically isotopes of hydrogen combine to form a single, heavier nucleus. They’re developing new materials and technologies to maintain stable plasma and confinement properties closer to what’s required in a fusion reactor.Įmbark on an electrifying journey as we unravel the mesmerizing secrets of nuclear fusion, unveiling its awe-inspiring mechanics, extraordinary applications, and boundless advantages! Nuclear Fusion: An Exact Definition Researchers from all over the world are working to achieve net fusion energy. Nuclear fusion is the process of releasing energy through combining atomic nuclei. A mix of deuterium and tritium could produce a terajoule with just a few grams - enough to meet one person’s energy needs for sixty years! It can generate four times more than fission (used in nuclear power plants) and nearly four million times more than burning oil or coal. It’s an incredible goal!įusion is an extraordinary source of energy. If we can do it, the energy could be limitless, clean, safe, and affordable. Scientists and engineers have been trying for decades to create nuclear fusion.
