An example of nuclear fission might be a nuclear weapon. In this device, sub-critical masses of fissionable material are driven together by conventional explosives. This "assembles" a critical mass, and a chain reaction will follow. That is a nuclear fission chain reaction. In another example, a nuclear reactor has its control rods pulled and achieves criticality. It is brought to operating temperature and generates heat to make steam and drive turbines. The reactor operates on the principle of nuclear fission.
One type of atom (element or isotope) is converted to another. This is called nuclear reaction.
The nuclear chain reaction in a nuclear reactor is started by the splitting of uranium atoms, a process known as nuclear fission.
In a nuclear reaction, matter is converted into energy.
The part of a nuclear reactor where the nuclear reaction takes place is called the reactor core. It typically contains the fuel rods, control rods, and coolant necessary for sustaining and controlling the nuclear reaction.
A nuclear fission reaction occurs in a nuclear power plant. This is the process where the nucleus of an atom is split, releasing large amounts of energy in the form of heat, which is used to generate electricity.
An example of a nuclear reaction is nuclear fusion, where two light atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy in the process. This reaction is the process that powers the sun and other stars.

One type of atom (element or isotope) is converted to another. This is called nuclear reaction.
The minimum amount of material needed to sustain a nuclear reaction depends on the type of reaction. For example, in a nuclear fission reaction, a critical mass of fissile material is needed to sustain a chain reaction. In a fusion reaction, high temperatures and pressures are needed to overcome the electrostatic repulsion between nuclei.

Plutonium is a by product of nuclear reactions of uranium in a nuclear reactor. An example of reaction is: 23892U + n-------23992U-------23993Np + e--------23994Pu + e
One example of a nuclear reaction involving beryllium is the reaction of beryllium-9 with an alpha particle (helium-4 nucleus) to produce carbon-12 and a neutron. This reaction is important in stellar nucleosynthesis and occurs in high-energy environments such as inside stars.
