control rods.
A control rods is the right answer
In a fission reactor, control is implemented by inserting control rods into the reactor. These are made of a material that absorbs neutrons, and prevents a reaction from taking place.
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.
Reactions that involve nuclei, called nuclear reactions, result in a tremendous amount of energy. Two types are fission and fusion.

Controlled! ...if the reactor is working properly.
It is a device where a controlled nuclear fission chain reaction occurs.

controlling a chain reaction
A nuclear reactor will do what is asked here. Use the link below to the related question about what a nuclear reactor is.
The term reactor refers to a structure in which material can be made to undergo a controlled nuclear reaction. They are used widely in industrial plants.
an atom bomb is uncontrolled and the reaction is over in a few microsecondsa reactor is controlled and the reaction can continueuninterrupted for years or longer
Nuclear reactors contain rods made of materials which will absorb neutrons. This reduced the cascade of neutrons which are responsible for the chain reaction.
the controlled release of nuclear energy in a reactor is accomplished
A nuclear reactor works by setting up a chain reaction in which the rate of fissions is steady, this is controlled by the control rods. Provided it is designed properly with adequate safety margins, a reactor is stable. Also there are safety systems which will shut it down quickly by inserting the control rods fully, in the event of design parameters being exceeded.
Nuclear reactions in a nuclear reactor are controlled reactions. The reactions in the atomic bomb are not controlled reactions
