The details of Werka’s initial generation FFRE can be found in the diagram below. The reaction chamber is about 5.4 meters in diameter by 2.8 meters long. The magnetic nozzle brings the length to 11.5 ...

This self-sustaining reaction is known as "criticality." Fission bombs. A mushroom cloud rising from the first atomic explosion, which was detonated July 16, 1945 near Alamagordo, ...

Per unit mass, the reaction produces 4 times more energy than the fission of U235. The fuel ion deuterium is incredibly abundant on Earth and in the universe. Tritium is radioactive with a half ...

For a sustained, controlled chain reaction, each fission must induce just one additional fission. Any more, and there'd be an explosion. Any fewer and the reaction would peter out.

Nuclear fission is a reaction where the nucleus of an atom splits into two or more smaller nuclei, while releasing energy. For instance, when hit by a neutron, the nucleus of an atom of uranium-235 ...

The H-bomb's force comes from both fission and fusion. In order to start a fusion reaction, the hydrogen bomb consists of two stages: the primary stage and the secondary stage.

That's because of the two main uranium isotopes, only uranium-235 can support a fission chain reaction: ... Adding up Feynman diagrams to make predictions about real materials. Jul 10, 2025.
