Nuclear energy was used in World War II to detonate two nuclear warheads over Hiroshima, Japan, on August 6, 1945, and over Nagasaki, on August 9, 1945.
The Hiroshima weapon was comprised of two subcritical mases of 235U92, that were driven into each other by conventional explosives, going super prompt critical and exploding.
The Nagasaki weapon was comprised of a sphere of 239Pu94 surrounding a polonium/beryllium neutron initiator, all surrounded by shaped charges of convertional explosives. The same mechanism applies on detonation.
Some sources state a different configuration, in that the Hiroshima weapon was actually 239Pu94 , while the Nagasaki weapon was actually 235U92, surrounded by layers of Beryllium. The opposite seems more correct, from a physics standpoint, so this is either a misunderstanding by this auther, a mistatement by some older documents, or by mis-information. Any one with better knowledge is, of course, welcom to refine this answer.
No.
Nuclear weapons have only been used in anger in the Second World War (WW2) - they were used against the Japan to bring the war to an end.
No nuclear weapons have been used since World War 2. There were testings done by Russia and possibly other countries but they were never used against other nations.
Dropped on Japan to end the war.
In war, never.
During World War 2, and it was made by test reactors.
The energy production in nuclear reactors. The atomic bombs used in World War ll. Apex.
Nuclear bomb.
It is thought that World War III will be a nuclear war.
No.
The United States used nuclear bombs on Japan in world war two.

Nuclear bombs were used in world war II but not in world war I

The energy production and nuclear reactors.The atomic bombs used in World War II. APEX -_- ik bc I got it incorrect from the other person who answered
The invention of the nuclear bomb painted way the mass production of nuclear arms and helped invent nuclear energy
Dropped on Japan to end the war.
