Nuclear Implosions

Nuclear implosion refers to a method used in nuclear weapons to initiate a nuclear explosion. In this process, conventional explosives are arranged around a subcritical mass of fissile material (such as plutonium-239 or uranium-235) in a specific configuration. When the explosives are detonated, they create an inward-directed shockwave that compresses the fissile material to a supercritical state, triggering a nuclear chain reaction and resulting in a massive explosion.
