Modern nuclear weapons work by combining chemical explosives, nuclear fission, and nuclear fusion.Nuclear weapon. A nuclear weapon, nuclear bomb or a nuke, is a weapon that suddenly releases the energy in the nucleus of certain types of atoms. When triggered, the device releases a huge amount of energy in the form of a nuclear explosion. Nuclear explosions can destroy a city and kill most of its people. There is a certain limit at which the bomb will blow itself apart before it can fully blow itself up, if that makes sense. So fission bombs have a maximum size. By the way, fission is how nuclear power plants work too, just slower and more controlled. Fusion Bombs (or "thermonuclear" or "hydrogen" or "H" bombs) work in the opposite way.
