Nuclear Fission - Two consequences of nuclear reactions are the phenomena of nuclear fission and nuclear fusion. Both are important sources of nuclear energy, which may be used for peaceful or destructive purposes. When a nucleus is bombar..

. Nowadays other bombarding particles (i.e., projectiles) like protons ( 1 H 1 ), deutrons 1 H 2 electrons can be accelerated to very high speeds by fluctuating electric and magnetic fields in machines such as cyclotron, synchrotron etc. These high speed particles are more efficient in causing nucl..

Once the nucleus has been divided by fission, the neutrons that are emitted can strike other nuclei. This energy released is extremely large. The neutrons produced during the fission are called secondary neutrons. These neutrons may bring about the fission o..

. Nuclear energy is produced in a nuclear reactor which is a device to generate electricity and used Uranium-235 as its fuel. In this reactor the energy released is controlled or sustained which is called as sustained fission reaction. Otherwise the energy goes out of ..

Fission in uranium-235 is brought by slow speed neutron. Heavy water is used for this purpose in nuclear reactors as moderator..

It has been found that the stability of nucleus depends upon its neutron to proton (n/p) ratio. A plot of N (the neutron number) against Z (atomic number or number of protons) show that for stable nuclides upto Z = 20, N = 20 i.e., the relationship can be represented by a line w..

A nuclear reactor is a device for obtaining and using the energy from a controlled nuclear chain reaction. Controlled means the rate or speed of the nuclear fissions can be changed by the operator. Most reactors are constructed in a similar manner. The six ma..
