Nuclear weapon - Simple English Wikipedia, the free encyclopedia
A nuclear weapon, nuclear bomb or a nuke, is a weapon that suddenly releases the energy in the nucleus of certain types of atoms. When triggered, the device releases a huge amount of energy in the form of a nuclear explosion .
Early nuclear weapons – Nuclear Weapons Education Project
By 1945 there was enough material on hand for only a few nuclear weapons. If more weapons than the Trinity test and the two that were dropped were needed to force Japan to surrender, the US war-planners needed a rapid material production technology that could produce more weapon materials in a short time- thus the plutonium pathway was followed ...

How Nuclear Weapons Work | Union of Concerned Scientists
2016年9月29日 · Modern nuclear weapons work by combining chemical explosives, nuclear fission, and nuclear fusion. The explosives compress nuclear material, causing fission; the fission releases massive amounts of energy in the form of X-rays, which create the high temperature and pressure needed to ignite fusion.
Nuclear Weapons - Nuclear Threat Initiative
What are nuclear weapons? nuclear weapon is a weapon that derives its incredible destructive force from the sudden release of the energy created by a self-sustaining nuclear fission and/or fusion reaction.
