What is nucleus fission?

Answer 1

Nuclear fission is the splitting of an atomic nucleus. This fission event can occur spontaneously, or can be the result of something like a neutron capture event. A number of heavy elements are known to spontaneously break apart (fission). And other nuclei like, say, uranium 235 can capture a neutron which destabilizes the nucleus and induces nuclear fission to occur.

Answer 2

Nuclear fission is the splitting of a nucleus such as U235 or Pu239, which releases energy in the form of heat. In a nuclear reactor the fission rate is controlled to produce a steady power level, so that heat is produced to be transferred to a steam turbine/generator.

Answer 3

Division of a heavy atomic nucleus into two fragments of roughly equal mass, accompanied by the release of a large amount of energy, the binding energy of the subatomic particles.

The energy released in the fission of one uranium nucleus is about 50 million times greater than that released when a carbon atom combines with oxygen atoms in the burning of coal. The energy appears as kinetic energy of the fragments, which converts to thermal energy as the fragments collide in matter and slow down. Fission also releases two or three free neutrons. The free neutrons can bombard other nuclei, leading to a series of fissions called a chain reaction. The energy released from nuclear fission is used to generate electricity, to propel ships and submarines, and is a source of the vast destructive power of nuclear weapons.

Answer 4

Nuclear fission is the division of a heavy atomic nucleus into two fragments of roughly equal mass, accompanied by the release of a large amount of energy, the binding energy of the subatomic particles.

Answer 5

I believe nuclear fission is the splitting of atoms with other atoms to create nuclear reactions which in turn creates energy for nuclear power plants

Answer 6

This is the generation of energy by splitting one or more radioactive nuclides.
