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.

How is the rate of the fission in a nuclear reactor controlled?
By the control rods and by the moderator.
Are control rods of nuclear reactors used to stop a leak?
Not really. Control rods are used to start up and shut down a nuclear reactor.
What is the function of the control rods in a nuclear reactor?
They are used in nuclear reactor to control the rate of fission of uranium and plutonium. Because these elements have different capture cross sections for neutrons of varying energies, the compositions of the control rods must be designed for the neutron spectrum of the reactor it is supposed to control.
What control the chain reaction in a nuclear reactor?
The reason a nuclear chain reaction occurs is that one of the by products of a single reaction: the neutrons can start reactions of their own. So how do you stop a chain reaction? Stop these neutrons from causing any more reactions. This is done in nuclear reactors by placing control rods into the reactor core. These control rods are made of elements that can absorb the high energy neutrons without reacting themselves. Therefore, by moving these rods in and out of the reactor, the rate of reaction in a nuclear reactor can be easily controlled.
What does lower control rods result in?
We lower control rods to cool or shut down a nuclear reactor. Lowering control rods allows those rods to absorb more neutrons, and this limits or shuts the fission chain down.
How many control rods are there in a nuclear reactor?
The number of control rods in a reactor will vary with the size and the design.
What rods housed within a nuclear reactor?
fuel rods and control rods
What are the control rods in a nuclear reactor made of?
The control rods inside a nuclear reactor are made out of Boron.
Where can you find cadmiums?
nuclear reactor control rods
The chain reaction in a nuclear reactor is controlled by inserting what?
control rods.

The rate at which reactions occur in a nuclear reactor is regulated by?
number of control rods
What absorbs neutrons in a nuclear reactor and begins with C?
We see the use of control rods in a reactor to absorb neutrons. These rods are often made of boron.
What is the purpose of the cadmium rods in a nuclear fission reactor?
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.
If you wanted to slow down the chain reaction in a nuclear reactor would you remove or insert the control rods?
In order to slow down the chain reaction in a nuclear reactor, i.e. to reduce KEff, you would insert the control rods.
