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."

What else can I help you with?
How is a nuclear fission reaction controlled in a nuclear reaction?
Reactions that involve nuclei, called nuclear reactions, result in a tremendous amount of energy. Two types are fission and fusion.
How is a nuclear fission reaction controlled in nuclear reactor?
Reactions that involve nuclei, called nuclear reactions, result in a tremendous amount of energy. Two types are fission and fusion.
What is the splitting of an atoms nucleus into two smaller nuclei is called?
nuclear fission
What is the place where controlled nuclear fission reactions take place?
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.
What is it called when nuclear fission is repeated?
It is called nuclear chain fission reaction.

The process in which each split atom gives up neutrons?
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.
What is the splitting of an atoms nucleus into two smaller nuclei is called?
nuclear fission
Reactions involving the particles in the nucleus of an atom are called what?
Nuclear Fusion. This process involves 'fusing' together two smaller nuclei to form a bigger nucleus.
What is the place where controlled nuclear fission reactions take place?
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.
What is it called when nuclear fission is repeated?
It is called nuclear chain fission reaction.
What Metal used in nuclear reactions?
Nuclear energy appears as heat in a nuclear reactor. It comes from the fission of uranium or plutonium
Why is it called Nuclear Fission?
It is called nuclear fission as in this process the heavy nuclei are split into fragments (or fission products).
The splitting of an atom's nucleus into two smaller nuclei is called?
The splitting of an atomic nucleus into smaller nuclei is called nuclear fission.
What is the energy stored in the centre of atoms called?
The energy stored in the center of atoms is called nuclear energy. This energy is released during nuclear reactions such as fission or fusion.
How is a nuclear fission reaction controlled in a nuclear reactor?
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.
