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. He added that other nuclear powers can and do make new atomic parts. Beyond the weapon debate, critics of the atomic recycling warn that the nuclear storage complex is a disaster waiting to happen. A thermonuclear weapon, fusion weapon or hydrogen bomb ( H bomb) is a second-generation nuclear weapon design.
