How are atomic bombs made?

Answer 1

Much of the design particulars are top secret-Q but basically you need a mass of fissile material (usually plutonium) large enough to be able to reach supercritical mass and support an uncontrolled nuclear reaction. The explosion is triggered by compressing the plutonium by an implosion to assemble the initially subcritical mass into a supercritical mass rapidly (a couple milliseconds). once the material reaches supercritical mass, a neutron source is fired through it to start the reaction at the optimal time. about 4µs to 7µs later the bomb explodes. The longer the design is able to hold the bomb together, the higher the yield when it does disassemble.

Answer 2

An atomic bomb is made by combining fissile material (such as enriched uranium or plutonium) in a critical mass to create a chain reaction of nuclear fission. This chain reaction releases a massive amount of energy in the form of an explosion. The process of making an atomic bomb is highly complex and requires advanced knowledge of nuclear physics and engineering.
