The word ‘nuclear’ refers to the center or nucleus of an atom. is the chief method of producing nuclear energy. It involves using a neutron to split the nucleus of a heavy element, such as uranium, into fission fragments. Besides heat energy, fission releases neutrons and such radiation as gamma rays. Nuclear fusion is an ....

.... this process is repeated over, it becomes a self-sustaining chain reaction. This energy producing process is called a chain reaction. uses the uranium-235 element because it is the easiest of all atoms to split apart. Uranium-235 is made up of many protons and few neutrons. Protons naturally repel one another so a nucleus made up of many protons tends to ‘fly apart’ more easily. In addition, uranium makes a good nuclear reactor because it can sustain a series of fission reactions, each time producing more ne ....
