Nuclear fission, radioactive decay reaction where heavy nucleus (uranium or plutonium) of atom subdivided or split into two or more smaller, lighter nuclei 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. Nuclear fission is a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into two or more smaller, lighter nuclei. Nuclear fusion is the lifeblood of stars, and an important process in understanding how the universe works. The steps are: Two protons within the Sun fuse. The process is what powers our own Sun, and therefore is the root source of all the energy on Earth. In fact, over a third of all the different kinds of atoms, when fused, release energy. Find out how it will work in this step-by-step graphic. Nuclear Fusion is a nuclear process, where the energy is generated by smashing together light atoms. To illustrate, suppose two nuclei, labeled X and a, react to form two other nuclei, Y and b, denoted X + a → Y + b. The newly measured rate of a key nuclear fusion process that forged the first atomic nuclei matches the picture of the universe 380,000 years later. Most of the energy produced this way that benefits humans and other life forms comes from the sun. The arrangement of particles within uranium-235 is somewhat unstable and the nucleus can disintegrate if it is excited by an outside source. In fission, an atom is split into two or more smaller, lighter atoms. Hydrogen is the simplest of all atoms. Fusion is the process that powers active stars, releasing large quantities of energy. A visual representation of this process is shown in Figure 1. The carbon-burning process or carbon fusion is a set of nuclear fusion reactions that take place in the cores of massive stars (at least 8 ⊙ at birth) that combines carbon into other elements. When a U-235 nucleus absorbs an extra neutron, it quickly breaks into two parts. This process is called nuclear fusion. Being a nuclear reaction that turns one element into another without destroying the atoms (nuclear fission destroys the atoms to generate energy, while nuclear fusion turns one element into a heavier one with the release of clean energy in the process), nuclear fusion can be easily controlled and stopped when necessary. This process is known as fission (see diagram below). Researchers have been trying to harness fusion and reproduce it on earth in a controlled manner. In physics, nuclear fusion is the process by which multiple nuclei join together to form a heavier nucleus. Nuclear Fission Nuclear fission of heavy elements was discovered in 1938 by German Otto Hahn and Fritz Strassmann. Nuclear fusion is the process of binding nuclei together to form heavier nuclei with the release of energy. Nuclear fusion-- the process by which the sun produces energy -- involves bringing together two smaller atoms to form a larger one. Nuclear Fusion Introduction. Nuclear fission Jonny Nelson introduces an animated explanation of fission and fusion In a nuclear reactor , a neutron is absorbed into a nucleus (typically uranium-235). During this process, matter is not conserved because some of the mass of the fusing nuclei is converted to energy, which is released. It is the contrary reaction of fission, where heavy isotopes are split apart. This is a point we will return to later, but for now we will concentrate on the simplest form of nuclear fusion, that of hydrogen. CBSE Class 10 Science - Sources of Energy - Understand how Nuclear energy is generated and what is Nuclear Fission and Nuclear Fusion. Why does it take something like the Sun to do it? These figures for temperature and density are only a guide. The overall process of proton-proton fusion within the Sun can be broken down into several simple steps. A process in which two or more lighter atoms combine to create a heavy nucleus is called nuclear fusion. Research into producing nuclear fusion on Earth began in the early 1950s with the development of the Hydrogen bomb.
