=   ﻿ ﻿ ﻿ ﻿ This page explains the use of the Nuclear power applied to Electricity, with the purpose of give you a better understanding of this kind of energy and its applications.=

=**Applications of Nuclear technology.**= =The medical applications of nuclear technology are divided into medical diagnosis such as using [|Scientific Imaging Equipment]:X-ray, CT-Scan, Nuclear Magnetic Resonance-Imaging; and medical treatment such as radiation treatment for cancer.=
 * There are many fields where the Nuclear Technology is applied, for example: **

**How to Produce Nuclear Energy **
====**First of all, we want to know how to produce Nuclear Energy, and that's what we are going to explain in a simple way. There are two ways to create Nuclear Energy which are by Fission and by Fusion.** ====

= Fission  =

=The first one is fission which is the splitting of a massive nucleus because it is hit by high energy neutron, into other elements and free neutrons + energy.= = Example: Uranium fission produces two new nucleus and at the same time 3 new neutrons goes out and a lot of energy. =

236 U + 1n = 144 Ba + 89 Kr + 3n + 177 MeV

= Fusion  =

=The second one is by fusion which is the reaction of 2 or more nuclei combined together to form a new element.= =Example: two light nucleus like Deuterium and Tritium hits each other with great temperature and they fuse into a Helium nucleus and produces a neutron and a large amount of energy.=

2 Deuterium + 3 Tritium = 4 He + 10n + 17.6 MeV
=The energy released in the fusion reaction is actually the main energy source of the sun and the stars.=

= Definition of Nuclear Power. =

=Nuclear power is the production of energy by controlled nuclear reactions. Utility and commercial plants use nuclear fission to obtain steam heating the water, which is used to generate electricity.=

Fission makes Heat
=We already explained how a neutron strikes an atom of uranium and the uranium atom splits into two lighter atoms (which are called fission products) and releases heat at the same time. this process also releases from one to three more neutrons that can split other uranium atoms. This is when the "chain reaction" beginning because more and more uranium atoms are split, releasing more and more neutrons and more and more heat. Now, in a nuclear reactor, the chain reaction is tightly controlled to produce only the amount of heat needed to generate a specific amount of electricity.=

= Heat makes Steam =

=When the heat is generated by he fission process, it has to be moved to boilers to make steam. In a nuclear reactor, heavy water (this is alike the normal water but with deuterium isotopes) and some times regular water does this job. It is pumped constantly through the fuel channels in the reactor and takes the heat from the fuel bundles up to boilers above the reactor. In the boilers the heated heavy water heats up ordinary water to make steam. The steam is piped out of the boilers and over to the turbine hall where it drives the huge turbines or generators that make the electricity we use.=

= Conclusion. =

==In addition to the broad applications that have this technology and the increasing energy demand and the scarcity of nonrenewable natural resources, alternative energy nuclear generation could be an efficient source if it's handled properly to meet the energy that we need for our daily life.==
