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, ...

In the process of nuclear fission, an unstable nucleus splits into two smaller atoms in a reaction that releases energy. A nuclear chain reaction occurs when one reaction causes additional reactions.

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.

The actual reaction occurs at about 1:48 into the video. The experiment was conducted for an AP Chemistry Class at the Horizon Science Academy Cleveland High School (HSA) .

Physicists have solved a long-standing puzzle about mercury’s nuclear fission by using a five-dimensional model that ...

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.

Fusion is among the most environmentally friendly sources of energy. There are no CO2 or other harmful atmospheric emissions from the fusion process, which means that fusion does not contribute to ...
