Thermonuclear Weapons
Thermonuclear Weapons : A nuclear weapon that derives a substantial part of its explosive energy from nuclear fusion. Such weapons are sometimes called H-bombs, because they use hydrogen isotopes (typically a few kg of deuterium and tritium) as the fuel for the fusion process. Thermonuclear weapons use fission devices as a trigger. The energy yieLd of a thermonuclear weapon can be much larger than that of an atomic bomb of comparable size
