Which is are used in nuclear reactors to absorb neutrons?
Control rods, such as boron or cadmium, are used in nuclear reactors to absorb neutrons and regulate the nuclear fission process. By adjusting the position of these control rods, the rate of reactions can be controlled to maintain the desired power levels within the reactor.
Which are used in nuclear reactors to absorb neutrons?
Control rods, such as boron or cadmium, are used in nuclear reactors to absorb neutrons and regulate the rate of the nuclear reaction. By adjusting the position of these control rods, the reactor operators can control the power output of the reactor and ensure safety.
Why is graphite used in nuclear reactors?
Graphite is used in nuclear reactors because it has the ability to slow down neutrons, which helps control the nuclear fission process and maintain a stable reaction. This helps regulate the release of energy and prevent the reactor from overheating.
Are control rods in nuclear reactors made of graphite?
No, control rods in nuclear reactors are not made of graphite. The control rods have to be able to gather up the neutrons to shut the reactor down, so boron is often selected. Graphite is used in some reactors as a moderator, and a moderator slows down neutrons. The slower neutrons have a greater ability to undergo neutron capture to continue the chain.
Why water is used as a coolant to some nuclear reactors?
Water is commonly used as a coolant in nuclear reactors because it has a high heat capacity, meaning it can absorb large amounts of heat without increasing in temperature significantly. Water also acts as a moderator, slowing down the neutrons released during fission reactions, facilitating the chain reaction process. Additionally, water is abundant and relatively inexpensive, making it a practical choice for cooling nuclear reactors.
What in nuclear reactors to absorb neutrons?
Control rods, typically made of materials such as boron or cadmium, are used in nuclear reactors to absorb neutrons and regulate the nuclear reaction. By controlling the number of neutrons present, the rate of fission reactions can be managed to maintain a steady level of power generation.

What element is used in the control rods of nuclear reactors?
One or more elements that strongly absorb neutrons, some are:cadmiumboronhafniumetc.
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.
How is plutonium used in nuclear reactors?
Plutonium is used in nuclear reactors as a nuclear fuel (as dioxide, carbide or MOX). The isotopes 239Pu and 241Pu are fissionable with thermal neutrons; other isotopes are fissionable only with fast neutrons.
How much temperature can be controlled by liquid sodium in nuclear reactors?
Liquid sodium has been used as a coolant in fast reactors, because it does not slow down and absorb fast neutrons. It does not control the nuclear reaction directly, for that variable neutron absorbers are required.
How is cadmium a part of nuclear reactors?
Cadmium is used in nuclear reactors as a control rod material. Control rods are inserted into the reactor core to absorb neutrons and regulate the nuclear fission process. Cadmium has a high neutron absorption cross-section, making it effective for controlling the rate of nuclear reactions.
Is moderation of neutrons always used to slow nuclear fission?
No, moderation of neutrons is not always used to slow nuclear fission. In some types of nuclear reactors, such as fast breeder reactors, fast neutrons are intentionally not moderated to slow down the fission process. These reactors operate using fast neutrons to sustain a chain reaction. However, in most commercial nuclear reactors, moderation of neutrons is employed to slow down the fission process and maintain a controlled chain reaction.
Are control rods made of graphite in a nuclear reactor?
Control rods in a nuclear reactor are typically made of materials like boron or cadmium that can absorb neutrons to regulate the nuclear reaction. Graphite is used as a moderator to slow down neutrons in certain types of reactors, but it is not typically used in control rods.
What materiel is used in nuclear reactors for absorbing neutrons?
Usually boron and its compounds as well as cadmium are used for absorbing unnecessary neutrons.
What are used in nuclear reactors to absorb neautron6neutrons?
Control rods made of materials like boron or cadmium are used in nuclear reactors to absorb neutrons and help regulate the power level by controlling the rate of fission reactions. By adjusting the position of these control rods within the reactor core, operators can fine-tune the neutron flux and maintain safe and stable operation.
