The Teller–Ulam design is a technical concept behind modern thermonuclear weapons, also known as hydrogen bombs. The design – the details of which are military secrets and known to only a handful of major nations – is [ citation needed ] believed to be used in virtually all modern nuclear weapons that make up the arsenals of the major ...
If natural uranium is enriched to 3% U-235, it can be used as fuel for light water nuclear reactors. If it is enriched to 90% uranium-235, it can be used for nuclear weapons. Diagram of the principles of a Zippe-type gas centrifuge with U-238 represented in dark blue and U-235 represented in light blue.
The Joe-1 atomic bomb test by the Soviet Union that took place in August 1949 came earlier than expected by Americans, and over the next several months there was an intense debate within the U.S. government, military, and scientific communities regarding whether to proceed with development of the far more powerful Super.

Nuclear power research was initiated at NRL as early as 1939, [4] six years before the first atomic bomb, for the purpose of powering submarines. Uranium enrichment methods sponsored by NRL over the course of World War II were adopted by the Manhattan Project [ 44 ] and guided the design of Oak Ridge National Laboratory 's Uranium enrichment plant.
Australian physicist Mark Oliphant was a key figure in the launching of both the British and United States nuclear weapons programmes. The 1938 discovery of nuclear fission in uranium by Otto Robert Frisch, Fritz Strassmann, Lise Meitner and Otto Hahn, [1] raised the possibility that an extremely powerful atomic bomb could be created.

In order to better understand the blast and thermal effects of a nuclear bomb, the US dropped a 16-kiloton bomb on a fake town in the middle of Nevada. Creepy photos show a fake 1950s city filled ...
The first nuclear explosive devices provided the basic building blocks of future weapons. Pictured is the Gadget device being prepared for the Trinity nuclear test.. Nuclear Weapons Design are physical, chemical, and engineering arrangements that cause the physics package [1] of a nuclear weapon to detonate.
