This process releases a tremendous amount of energy in the form of an explosion and additional neutrons, which can then cause a chain reaction. The two primary physical processes that enable this conversion are nuclear fission and nuclear fusion, and they define the classification of these weapons.
Inside the Nuclear Weapon Process: Fission, Fusion, and Energy Release
This process releases even more energy than fission and is the same reaction that powers the sun and stars. The destructive power seen in the 1945 blasts was horrific and world-changing, but it pales in comparison to the multi-megaton yields of modern thermonuclear devices.
Scientists theorized that if the atom, once thought to be indivisible (hence "a-tom," meaning indivisible), could be split, it would unleash phenomenal energy. The Science of Fission and Fusion At the heart of every explosive device designed to harness atomic energy is the process of releasing immense power from the nucleus of an atom.
How Nuclear Fission and Fusion Power Modern Thermonuclear Devices
Historical Context and Terminology The origin of the term "atomic bomb" dates back to the early 20th century, long before the weapon was ever built. Fusion: The Combining Process Nuclear fusion, on the other hand, involves forcing two light atoms, typically isotopes of hydrogen like deuterium and tritium, to combine into a heavier atom, such as helium.
