No, the function of the control rods is to absorb surplus neutrons so that the chain reaction proceeds at a steady rate, and to compensate for the reducing reactivity of the reactor as the fuel is burned up over the refuelling cycle. They also have a very important safety function in shutting down the reactor fully when required, by inserting them fully, thus preventing any chain reaction from starting.

The rate at which reactions occur in a nuclear reactor is regulated by?
number of control rods
In a nuclear power plant fission reactions are controlled by inserting what?
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.
What is the place where controlled nuclear fission reactions take place?
In the core of a nuclear reactor
What is the difference between the nuclear reactions taking place in the sun and in a nuclear reactor?
the suns nuclear reactions happen at extreme temperatures we do it at lower temps
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 is the difference between the nuclear reactions in a nuclear reactor and those in an atomic bomb?
Nuclear reactions in a nuclear reactor are controlled reactions. The reactions in the atomic bomb are not controlled reactions
The rate at which reactions occur in a nuclear reactor is regulated by?
number of control rods
Primary function of moderator in nuclear reactor?
What is the primary function of a Moderator in a nuclear reactor
What is the difference between the nuclear reactions taking place in the sun and the nuclear reactions taking place in a nuclear reactor?
The sun's nuclear reactions are fusion reactions at extremely high temperatures and pressures, while the nuclear reactor's nuclear reactions are fission reactions at typical temperatures and pressures for earth.
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 is the function of a nuclear reactor of a nuclear plant?
simply, the nuclear reactor is the source of heat (or steam) for the nuclear power plant.
The function of control rods in a nuclear reactor is to speed up the nuclear reactions?
Control rod act as brakes to reduce the reaction rate. However as nuclear reactors have so much excess reactivity, its like a car rolling downhill: remove the control rods a bit (release the brakes some) and the reaction rate increases.
What is the function of an electrical reactor?
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.
In a nuclear power plant fission reactions are controlled by inserting what?
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.
What is nuclear reactor kinetics?
Nuclear reactor kinetics is the branch of reactor engineering and reactor physics and control that deals with long term time changes in reactor fuel and nuclear reactors.
