I found this: " The control rods, another important part of the reactor, regulate or control the speed of the nuclear chain reaction, by sliding up and down between the fuel rods or fuel assemblies in the reactor core. The control rods contain material such as cadmium and boron. Because of their atomic structure cadmium and boron absorb neutrons, but do not fission or split. Therefore, the control rods act like sponges that absorb extra neutrons."

Reactions that involve nuclei, called nuclear reactions, result in a tremendous amount of energy. Two types are fission and fusion.

nuclear fission
The place where controlled nuclear fission reactions take place is called a nuclear reactor. In a nuclear reactor, uranium atoms are split in a controlled manner to produce heat energy, which is used to generate electricity.
It is called nuclear chain fission reaction.

The act of an atom splitting is called nuclear fission. In nuclear fission where we see neutrons emerge with fission fragments, and we then see those neutrons initiate other fission reactions is called a nuclear fission chain reaction.

Nuclear Fusion. This process involves 'fusing' together two smaller nuclei to form a bigger nucleus.

It is called nuclear chain fission reaction.
Nuclear energy appears as heat in a nuclear reactor. It comes from the fission of uranium or plutonium
It is called nuclear fission as in this process the heavy nuclei are split into fragments (or fission products).
The splitting of an atomic nucleus into smaller nuclei is called nuclear fission.
The energy stored in the center of atoms is called nuclear energy. This energy is released during nuclear reactions such as fission or fusion.
A nuclear fission reaction is controlled in a nuclear reactor by using control rods made of materials that absorb neutrons, such as boron or cadmium. By adjusting the position of these control rods within the reactor core, the rate of fission and thus the power output can be regulated. Inserting the control rods absorbs neutrons and reduces the number available for further fission reactions, helping to maintain a steady power level.
