Energy is the ability and capacity to do any type of work. There are different forms of energy- like Potential Energy, Kinetic Energy, Thermal Energy, Electrical Energy, Mechanical Energy, Chemical Energy, nuclear Energy. Energy can be neither created nor destroyed. Nuclear Energy is the energy which is stored in the nucleus of an atom. When the nucleus of an atom splits or when two nuclei of different atoms combine, a large amount of energy is released in the form of heat and radiation. Their energy is termed as Nuclear Energy. Nuclear processes are used in order to generate heat or electricity from nuclear energy. These nuclear processes are performed using the earth elements. During these processes the nuclei of atoms either join together which is called fusion or they break apart which is called fission. This fusion is basically the fusion of hydrogen into helium. The fission can come from the fission of uranium, plutonium or thorium. As the world is getting more modernized and advanced the need for more energy is increasing. There is a shortage supply of fossil fuel, the construction of new hydroelectric power station is also limited. Hence the nuclear power has shown a fast development. More and more countries have understood the need for nuclear energy. Nuclear energy is the outcome of the nuclear reaction took place in radioactive metals which could be utilized in the form of heat energy. The heat energy produced during the nuclear reaction used to operate steam
