NuclearFissionNuclear ﬁssion is a process in which the nucleus of an atom is split into two or more smaller nuclei, known as ﬁssion products.
The strong nuclear force is the force between two or more nucleons (protons and neutrons are often called nucleons when dealing with nuclear chemistry).
In atoms where the nuclei are small, the strong nuclear force overpowers the electromagnetic force.
This instability can result in radiation and fission.
While nuclearfission can occur without this neutron bombardment (spontaneous fission), this is a rare occurrence, and most fission reactions (especially those utilized for energy and weaponry) occur via neutron bombardment.
Nuclearfission occurs when an atom splits into two or more smaller atoms, most often the result of neutron bombardment.
Reactors and Fission The energy released from nuclearfission can be harnessed to make electricity with a nuclear reactor.
However, nuclear reactors produce of nuclear waste containing radioactive elements.
THE CHAIN REACTION When a large, fissile atomic nucleus such as uranium-235 or plutonium-239 absorbs a neutron, it may undergo nuclearfission.
Nuclear reactors generally have automatic and manual systems to shut the fission reaction down if unsafe conditions are detected.
GENERATING ELECTRICITY Just as many conventional thermal power stations generate electricity by harnessing the thermal energy released from burning fossil fuels, nuclear power plants convert the energy released from nuclearfission.
A nuclear reactor is a piece of equipment in which nuclear chain reactions can be harnessed to produce energy in a controlled way.
