In recent years, we began to understand the enormous power generated by nuclear energy. In the years just before and during World War II, nuclear research focused mainly on the development of defence weapons. Later, scientists concentrated on peaceful applications of nuclear technology. An important use of nuclear energy is the generation of electricity. After years of research, scientists have successfully applied nuclear technology to many other scientific, medical, and industrial purposes.

What is Nuclear energy?

The energy released when two atoms are made to bombarded with each other is generally called as nuclear energy. Nuclear energy uses sustained nuclear fission to generate heat and electricity. This energy is not only used to generate electricity but also used to create atomic bombs.

Although they are tiny, atoms have a large amount of energy holding their nuclei together. Certain isotopes of some elements can be split and will release part of their energy as heat. This splitting is called fission. The heat released in fission can be used to help generate electric energy in power plants. An important event that is responsible for atomic energy is called Nuclear fission.

 

 

What is Nuclear energy?

The splitting of one atom into one or two atoms by releasing large amount of energy is called nuclear fission.

  • Uranium-235 (U-235) is one of the isotopes that fissions easily. During fission, U-235 atoms absorb loose neutrons.

  • This causes U-235 to become unstable and split into two light atoms called fission products.

A series of fissions is called a chain reaction. If enough uranium is brought together under the right conditions, a continuous chain reaction occurs. This is called a self-sustaining chain reaction. A self-sustaining chain reaction creates a great deal of heat, which can be used to help generate electricity and to create atomic bombs.


 

 

Role of nuclear technology in various fields

Nuclear technology plays an important role in many fields. The role of nuclear technology in various fields are explained below.

  • Nuclear technology is used in Food and Agriculture
  • Nuclear technology is used to save Human Health :
  • Nuclear technology is used in Sterilization
  • Nuclear technology is used in Tracing Pollutants
  • Nuclear technology is used in Detecting Leaks in Pipelines
  • Nuclear technology is used as Power Sources
  • Nuclear technology is used in Determination of Age
  • Nuclear technology is used in  Space
  • Nuclear technology is used in Generating Electricity

 

Important events in history of  nuclear technology

  • In 1780 German scientist Martin Heinrich Klaproth discovers Uranium. That becomes the keystone of nuclear technology

  • In march 1986 French scientist Antoine Becquerel discovers radioactivity.

  • In 1934 Italian scientist Enrico Fermi shows that neutrons can split atoms.

  • In July 1939 Enrico Fermi and Leo Sziland propose a idea of nuclear reactor that uses Uranium fuel.

  • In December 1951, First electric energy from a nuclear power plant was produced in Arco,Idaho. It powers  four electric bulbs.

  • Finally world’s first commercial nuclear power plant opens in obninsk soviet union. It has 6 megawatt capacity.
