- Carbon in the form of graphite is used in some types of reactors as the moderator*.
- Heavy water is used in some types of reactors as the moderator*.
- Light water is used in some types of reactors as the moderator*.
- Light water is used in most current types of reactors as coolant and in the form of steam to drive the turbines.
- Liquid metals (Sodium, NaK, Mercury, etc.) are used in some types of reactors as coolant.
- Concrete, often borated concrete to absorb neutrons better, is used in reactors as radiation shielding.
*Moderator: a material that slows highly energetic fission neutrons rapidly to thermal energies to prevent their capture by Uranium-238 and increase their chance of causing more fissions of Uranium-235 to keep the reactor running.

How heavy water is used to make plutonium from uranium?
Heavy water can be used in a nuclear reactor to moderate the speed of neutrons, making it easier for uranium-238 to absorb a neutron and become plutonium-239. This process is known as breeding plutonium in a reactor and is one method of producing plutonium for nuclear weapons or fuel.
In nuclear reactor heavy water is used as?
Heavy water (deuterium) functions as a moderator. It slows down fast neutrons released by fission reactions in order to allow the reaction to be sustained. Fast neutrons pass through the reactor before initiating another fission reaction.
What is the difference between the nuclear reactions taking place in the sun and in a nuclear reactor?
The nuclear reactions in the Sun primarily involve fusion of hydrogen nuclei to form helium, releasing energy in the process. In a nuclear reactor, the reactions typically involve fission of heavy nuclei like uranium or plutonium, releasing energy through splitting these nuclei. The conditions and mechanisms governing the reactions in the Sun and in a nuclear reactor are different due to the vastly varying scales and environments of the two systems.

What type of nuclear reactor is used in Ontario to produce electricity?
This is the Candu type, which was uniquely developed in Canada to use heavy water moderator and natural uranium fuel
What type of nuclear reaction occurs in a reactor?
Nuclear fission is the primary type of nuclear reaction that occurs in a reactor. It involves the splitting of heavy atomic nuclei to release energy.
The moderator used in the nuclear reactor at Madras atomic power station in Kalpakkam is?
The moderator used in the nuclear reactor at Madras Atomic Power Station in Kalpakkam is usually heavy water (deuterium oxide) or light water (ordinary water). These moderators are important for slowing down neutrons produced during nuclear fission reactions to sustain the chain reaction in the reactor.
What is a nuclear reaction coolant?
Presumably you mean nuclear reactor coolant? This is the fluid that transfers the reactor thermal output to the steam raising units in a PWR, or to the turbine in a BWR, in which cases it is natural water. Gas cooled reactors can use carbon dioxide or helium, and CANDU reactors use heavy water.
Introduction of nuclear fission and fission?
It is a process, in which a heavy nucleus is broken down in to two or more medium heavy fragments. It is used in nuclear reactor and atom bomb.
Name one type of nuclear reactor?
One type of nuclear reactor is the pressurized water reactor (PWR). In a PWR, the heat generated by nuclear fission in the reactor core is transferred to water, which circulates through the core to create steam that drives turbines to produce electricity.
How heavy water is used to make plutonium from uranium?
Heavy water can be used in a nuclear reactor to moderate the speed of neutrons, making it easier for uranium-238 to absorb a neutron and become plutonium-239. This process is known as breeding plutonium in a reactor and is one method of producing plutonium for nuclear weapons or fuel.
What is used to bathe the control rods and fuel bundles of the nuclear reactor?
Boric acid solution is used to bathe the control rods and fuel bundles of a nuclear reactor. This solution helps control the nuclear reaction by absorbing excess neutrons.
Are radioactive isotopes produced in a nuclear reactor?
Yes, radioactive isotopes are produced in a nuclear reactor through the process of nuclear fission, where heavy atomic nuclei are split into smaller fragments. These fragments, some of which are unstable and radioactive, can be used for various purposes such as medical imaging, cancer treatment, and scientific research.
What is a used fuel in nuclear power plants?
The used fuel in a nuclear power plant is the nuclear fuel being discharged from the nuclear reactor after being irradiated during reactor operation. It is usually composed of trans-uranium heavy elements, a wide variety of fission products (that resulted from the nuclear fission processes in the nuclear reactor) and products of radioactive decay (produced before and after fuel discharge from the nuclear reactor).
In nuclear reactor heavy water is used as?
Heavy water (deuterium) functions as a moderator. It slows down fast neutrons released by fission reactions in order to allow the reaction to be sustained. Fast neutrons pass through the reactor before initiating another fission reaction.
Which coolant is used in kalpakkam nuclear power plant?
The Kalpakkam nuclear power plant uses heavy water (deuterium oxide) as a coolant and moderator in its Pressurized Heavy Water Reactors (PHWRs). Heavy water has a higher density than regular water, allowing it to efficiently slow down neutrons and regulate the nuclear reaction in the reactor core.
How does a nuclear reactor shoot neutrons?
In a nuclear reactor, the fission process splits heavy atomic nuclei, releasing energy and additional neutrons. These neutrons can then collide with other nuclei, causing them to split and release more neutrons, creating a self-sustaining chain reaction. Controlling the number of neutrons and their interactions is crucial to the operation and safety of a nuclear reactor.
