Similar to nuclear fission, the mass of the resulting element does not exactly match the combined masses of the two smaller elements, but is converted to energy. E.g. The International School of Nuclear Law (ISNL), established in 2001 by the OECD Nuclear Energy Agency (NEA) in co-operation with the University of Montpellier, has been designed to provide participants with a comprehensive understanding of the various interrelated legal issues relating to the safe, efficient and secure use of nuclear energy. Nuclear energy was first, being used in World War II for creating atomic bombs. Nuclear chemistry is the sub-field of chemistry dealing with radioactivity, nuclear processes, and transformations in the nuclei of atoms, such as nuclear transmutation and nuclear properties. The best example of nuclear fusion is – hydrogen bomb. In 1938, German chemists Otto Hahn, Fritz Strassmann, and the Austrian physicist Lise Meitner conducted the experiments in which the products of neutron-bombarded uranium. Such reactions are slow and controllable; therefore, also known as controlled chain reaction. Civilians living within 50 miles (80 km) of a nuclear power plant typically receive about 0.1 μSv per year. These atomic bombs were made with, uranium. Nuclear power has played a role as an energy source for some time now and involves complex technology, has had an effect on society, and has has had both positive and negative effects throughout history. although nuclear energy may not be the only way to produce clean energy and to do it efficiently I still believe it does it the best. -The plot shows the use of nuclear reactions as source of energy.
-energy is released in a process which goes from a higher energy state (less stable, low binding energy) to a low energy state (more stable, high binding energy).
-Using the plot, there are two ways in which energy can be released in nuclear reactions:
a. Nuclear energy is the energy source that is obtained when radioactive atom is split into two. •Binding energy= the amount of energy released when a nucleus is formed. Chemistry plays a key role in transforming these biologically-derived materials into fuels and other useful chemicals. It gave off so much radiation and mass destruction to Hiroshima. A nuclear reactor is a machine used to inculcate a nuclear chain reaction. Nuclear energy was first being used in World War II for creating atomic bombs.
