5/1/2023 0 Comments Fission reaction![]() In the process of nuclear fusion also a tremendous amount of energy is released. Therefore, the process in which two nuclei of light electrons are combined to form a heavy nucleus is nuclear fusion. The meaning of fusion is to join or to combine. When we put these values in Einstein’s equation we get,ġ atomic mass unit (u) = 1.492 * 10 -10 J Since the absolute mass of atomic mass unit is 1.66 * 10 -27 kg and the exact value of the speed of light is 2.998 * 10 8m/s. Value of atomic mass unit in terms of energy And,ġ million electron volt = 1.602 * 10 -19 * 10 6 joules The SI unit of energy released in nuclear reactions is electron volt (eV) or million electron volt (MeV). Therefore, if one kg of mass of any matter is destroyed in a nuclear reaction than the amount of energy produced is:Įnergy units for expressing nuclear energy Also, if the mass is taken in kilograms (kg) and speed of light in meters per second (m/s) then energy will come in joules (J). Since the speed of light is large so an extremely large amount of energy is produced even if a small amount of mass is destroyed. This caused a tremendous loss of human life.Īccording to Einstein mass is equal to energy. The atom bombs based on nuclear fission of uranium-235 ad plutonium-239 were dropped on the Japanese cities of Hiroshima and Nagasaki in 1945 during the Second World War. The fission reaction is deliberately allowed to go out of control so as to produce a large amount of energy in a very short while. Vii) Kakrapar Atomic Power Station, GujaratĪ nuclear bomb is based on the nuclear fission reaction of uranium-235 and plutonium-239. Vi) Narora Atomic Power Station, Uttar Pradesh V) Kudankulam Atomic Power Station, Tamil Nadu Iv) Kaiga Atomic Power Station, Karnataka Iii) Madras Atomic Power Station, Tamil Nadu Ii) Rajasthan Atomic Power Station, Rajasthan I) Tarapur Atomic Power Station, Maharashtra There are seven nuclear power plants in India. The waste material produced in the nuclear fission reaction of uranium-235 is radioactive and extremely harmful to the environment. This steam then converts into the water and through pipes is again sent to the heat exchanger. The spent steam coming out of the turbine chamber is passed through the condenser which contains water and this water helps in cooling the steam. ![]() This generator helps in generating electricity. So, when the turbine rotates, its shaft also rotates and drives the generator. ![]() This steam then rotates the turbine which is further attached to its shaft and the generator. This steam is then passed at high pressure into the turbine chamber having a turbine. Water absorbs heat from hot sodium and boils to form steam. Then through pipes extremely hot sodium is passed through water in the heat exchanger. Sodium helps in absorbing the heat produced in the reactor. That is why liquid sodium is pumped continuously through the pipes attached to the reactor. A tremendous amount of heat energy is produced when a controlled fission reaction takes place in a nuclear reactor.
