neutron absorber
An artificial nuclear reactor is a nuclear reactor that is created by man to utilize a nuclear reaction for energy, as opposed to natural nuclear reactors.
Cadmium is a very strong absorber of neutrons and therefore can be used to control the chain reaction and to shutdown the reactor when required. Boron is also often used for the same purpose.
In order to slow down the chain reaction in a nuclear reactor, i.e. to reduce KEff, you would insert the control rods.
In a nuclear bomb temperatures of 10 million centigrade or more are produced. In a nuclear reactor temperatures of 100 centigrade to about 1000 centigrade are produced depending on type and design of reactor.

An artificial nuclear reactor is a nuclear reactor that is created by man to utilize a nuclear reaction for energy, as opposed to natural nuclear reactors.
Basically a chain reaction (nuclear or chemical) is a self sustaining auto-catalytic reaction.In a nuclear reactor it is a neutron chain reaction, where each neutron released in every fission event can trigger another fission event. In a nuclear reactor the excess neutrons must be disposed of, which is the purpose of the control rods so that the reaction can be kept at some desired constant rate.
A nuclear reactor requires the neutrons released from one reaction to trigger the fission of other nuclei. Control rods are required to absorb some of these neutrons so as to prevent a runaway chain reaction.
The nuclear reactor is a device where a controlled nuclear fission chain reaction occurs. Its purpose is for:propulsion (e,g for nuclear submarines and ice breakers)process heat (e,g, for district heating)electricity productionradioisotope productionresearchmaterial testingmedical treatmentsaline water desalination

Nuclear fission, not to be confused with fusion.
A nuclear reactor contains a nuclear reaction, provides support for the control mechanisms for the reaction, and provides for the transfer of heat to machinery that will use it to produce electric power.
