A pivotal scene in the explosive hit biopic and Best Picture winner, "Oppenheimer," involves America's top scientists ...

Man-made nuclear fission reactors work by carefully controlling a chain reaction where uranium-235 atoms are split by neutrons, releasing energy and more neutrons, which go on to split additional ...

The miniaturization of a powerful source of energy is already underway, and it will be safer and cheaper than traditional ...

IT has recently been shown that the number 1 of neutrons liberated 2 in the nuclear fission of a uranium nucleus is sufficiently high to make the realization of a self-perpetuating reaction chain ...

That collision—called nuclear fission—releases more neutrons that react with more atoms, creating a chain reaction. A byproduct of nuclear reactions, plutonium, can also be used as nuclear fuel.

By the end of the year the physicist Werner Heisenberg had calculated that nuclear fission chain reactions might be possible. When slowed down and controlled in a "uranium machine" (nuclear ...

An international team of scientists has identified an unexpected region of heavy, neutron-deficient isotopes in the nuclear chart where nuclear fission is predominantly governed by an asymmetric mode.
