Become a nuclear superpower... in ten steps - BBC
2014年11月18日 · So, what does it take to build a nuclear bomb? And why do few countries bother? BBC Future lays out the challenge and peril of any country wishing to undertake its very own nuclear weapons...
Nuclear weapon design - Wikipedia
In the ensuing fifty years, no one has come up with a more efficient way to build a thermonuclear bomb. It is the design of choice for the United States, Russia, the United Kingdom, China, and France, the five thermonuclear powers.
How to build and deliver a nuclear weapon - The World from PRX
2017年11月30日 · Following are the steps necessary to build and deliver a nuclear weapon: The raw material: uranium The key ingredient in a nuclear bomb is enriched uranium — or plutonium, which can be obtained through the combustion of uranium. Uranium is a relatively common mineral, found both in the ground and under the sea.
How to Build a Gun-type Bomb . The gun-type assembly method was the “obvious” way to construct a nuclear weapon. Two masses of subcritical size would be brought together quickly, resulting in a supercritical mass. The original design, called Thin Man after a popular movie title of the era, was to be 17 feet long.
So you want to design a bomb… Considerations: We need a fast chain reaction of fissions • Mean free path • Critical mass Trigger design • How the bomb is detonated Output and efficiency • Energy ouput of explosion • How much uranium underwent fission

2023年7月27日 · What is nuclear power and how can the same process that generates nuclear energy create a nuclear bomb?
Behind the Scenes at a U.S. Factory Building New Nuclear Bombs
2023年12月1日 · In 1945 the U.S. dropped a uranium fission bomb on Hiroshima and then sent a plutonium bomb—essentially a pit encased in explosives—to devastate Nagasaki.
Fissile Materials Basics | Union of Concerned Scientists
2009年7月18日 · In general, higher enrichment levels and lower intended yields mean less fissile material needed to make a bomb. The first working nuclear weapons were based on two basic design options: a "gun-type" weapon, in which two pieces of HEU are brought together quickly and explode, and an "implosion-type" weapon, in which a sphere of weapon-usable ...
Nuclear weapon - Gun Assembly, Implosion, Boosting | Britannica
5 天之前 · In order to produce a nuclear explosion, subcritical masses of fissionable material must be rapidly assembled into a supercritical configuration. The simplest weapon design is the pure fission gun-assembly device, in which an explosive propellant is used to fire one subcritical mass down a “gun barrel” into another subcritical mass.
The task of the Los Alamos staff was to design the bomb, and to devise methods of manu- facturing it, in advance of the scheduled deliveries of the needed material. A separate and remarkable story lies behind the fact that the scheduled deliveries were made on time.
