Nuclear Energy


Nuclear power is the energy emitted during nuclear transformations. Release of energy during these transformations is associated with differences in the binding energy of individual nuclei. Nuclear energy is the energy released in nuclear reactions (Ollhoff, 2010). However, it also referred as nuclear energy as the energy use for other purposes such as obtaining power, thermal, and mechanical energy from nuclear reactions. Nuclear energy is a physical chemical process in which energy releases large nuclear energy (Murray, 2009).

Types of Nuclear Energy

Nuclear energy is of two main types. These two types are as follows:

The Nuclear Fission

The Nuclear Fusion

The Nuclear Fission

Nuclear fission is one of two possible reactions that occur when working with nuclear energy. In nuclear fission, the division of an atom takes place. The summation of the masses of the fragments is less than the primary mass (Bodansky, 2004). This missing mass (about 0.1 out of 100 of the primary mass) has been changed into vitality as showed by Einstein's expression (E = mc 2). In this expression E is the vitality received, mc the mass of which was discussed, and c is an unfailing, the tempo of light: 299,792,458 m / s 2. With this worth of the unfailing c can now observe that for tiny unit of mass that we take in nuclear fission receive large allotments of energy.

When the heavy nucleus of an atom id captured in a neutron, it is said to be a nuclear fission. This can occur spontaneously. A chain reaction takes place in nuclear fission. A flexible chain of bonds response cites to a method in which neutrons liberated in fission generate a supplemental fission in a least one nucleus. This nucleus in turn creates neutrons, and the method repeats. The method can be controlled (nuclear power) or unrestrained (nuclear weapons).

The Nuclear Fusion

Nuclear fusion is a fission response in which two nuclei of light weight atoms, commonly hydrogen and its isotopes (deuterium and tritium) aggregate to configuration one heavier nucleus, distributing a large allotment of energy. A clear example is seen in everything from solar energy has its origin in the fusion of hydrogen nuclei, helium and releasing generating a large amount of energy that reaches Earth in the form of electromagnetic radiation. To make nuclear fusion reactions, it must meet the following requirements: very high temperature to separate the electrons from the nucleus, and it is close to another by overcoming the electrostatic repulsion forces. The gaseous mass composed of free electrons and highly ionized atoms is called plasma.

Confinement is necessary to maintain the plasma at high temperature for a short time. Plasma density sufficient for the nuclei is close to each other and can result in fusion ...
