FISSIONING Meaning and
Definition
-
Fissioning is a term primarily used in the field of nuclear physics and refers to the process of dividing or splitting an atomic nucleus into two or more smaller fragments. This phenomenon occurs when a heavy and unstable atomic nucleus, such as uranium-235 or plutonium-239, absorbs a neutron and becomes highly excited.
As the nucleus reaches a critical level of excitation, it becomes extremely unstable and undergoes spontaneous fission, breaking into two or more smaller nuclei, known as fission fragments. Along with the fission fragments, several additional neutrons are released in the process, enabling a self-sustaining chain reaction.
Fissioning is intrinsic to the functioning of nuclear reactors, where controlled fission takes place to generate vast amounts of energy by harnessing the chain reaction. This energy release is the basis of nuclear power and nuclear weapons. The process also plays a crucial role in understanding the behavior of radioactive materials.
Beyond nuclear physics, the term "fissioning" can be metaphorically applied to other contexts and fields, representing a division or separation into different and distinct parts or entities. In such cases, it signifies a splitting or breaking apart, often implying a significant change or transformation. This broader usage of the term can be seen in various scientific, societal, and cultural discussions where the concept of fissioning is employed to describe a process of divergence, fragmentation, or disintegration.
Etymology of FISSIONING
The word "fissioning" is the present participle form of the verb "fission". The etymology of "fission" can be traced back to the Latin word "fissio", which means "a splitting or cleaving". From Latin, it was borrowed into English in the mid-19th century and specifically used in the field of physics to refer to the process of splitting an atomic nucleus, which gives rise to nuclear energy.
