(Technically, fissile material can undergo fission with neutrons of any energy, whereas fissionable material requires high-energy neutrons. Some nuclei can undergo fission on their own spontaneously, but only specific nuclei, like uranium-235, uranium-233, and plutonium-239, can sustain a fission. Material that can sustain a nuclear fission chain reaction is said to be fissile or fissionable. For example, the atomic bomb dropped on Hiroshima, Japan, in 1945, containing. Their significance may best be appreciated by the coining of the words kiloton (1,000 tons) and megaton (1,000,000 tons) to describe their blast energy in equivalent weights of the conventional chemical explosive TNT. (Fission is the radioactive process used in nuclear power plants and one type of nuclear bomb.). For U 235 on average 2.5 neutrons are emitted, starting on average two more fission reactions. X-rays and Gamma rays are examples of ionizing radiation. One of the most well-known and useful examples of a chain reaction is of U 235 which is used to harness nuclear energy. The result of this split is normally two smaller nuclei (of different elements), free neutrons, and. The fission products produced in a nuclear. If this process continues, a nuclear chain reaction occurs. Nuclear weapons produce enormous explosive energy. Chain Reactions are basically fission reactions which through the products produce more chain reactions. Nuclear fission occurs when the nucleus of an atom is split. The most common fission products have mass numbers around 90 and 137 (for example, strontium-90 and cesium-137). Nuclear fission definition: the splitting of an atomic nucleus into approximately equal parts, either spontaneously. This is made possible through the use of a nuclear reaction. ![]() \): The fission of a large nucleus, such as U-235, produces two or three neutrons, each of which is capable of causing fission of another nucleus by the reactions shown. For example Uranium-235, which is a naturally occurring isotope of Uranium. In this section, we are going to solve two examples of the Nuclear Fission Equation to clarify this topic more.
