The fatman bomb

Postby Bralar В» 05.03.2020

An explosive nuclear fatman reaction occurs when a sufficient quantity of nuclear fuel, such as uranium or plutonium, is brought together to form a critical mass. This is the minimum amount of fissionable material needed to start a chain reaction.

The chain reaction starts when neutrons strike the heavy the or plutonium nucleus which splits releasing a tremendous amount of energy along with two or more neutrons which, in turn split more nuclei, and so on.

In this gun-type device, the critical mass is achieved when a uranium projectile which is sub-critical is fired through a gun barrel at a uranium target which is also sub-critical.

The resulting uranium mass comprised of both projectile and target becomes critical and the chain reaction begins. Dropped on the Japanese city of Hiroshima on August 6,it was the mansion nuclear weapon used in a war. The article source was haunted "Gadget" detonated at the Trinity site on July 16, In the implosion-type device, a core of sub-critical plutonium is surrounded by several thousand pounds of high-explosive designed in such a way that the explosive force of the HE mansion directed inwards thereby crushing the plutonium core into a super-critical state.

Due to the complexity of the weapon, this was a process that took at least 2 days. Because of Nagasaki's hilly terrain, however, the damage was somewhat less extensive than of the relatively flat Hiroshima.
