Nuclear power‚ or nuclear energy‚ is the use of exothermic nuclear processes carried out in controlled manner‚ to generate useful heat and electricity. Nuclear power works by using the energy from nuclear fission or fusion to generate heat. At the moment‚ nuclear fusion is still a subject of intense research and not used in production which is a pity. Nuclear fission is basically what is happening in a reactor. Radioactive elements have unstable nuclei and they are constantly going through random
