Which is are used in nuclear reactors to absorb neutrons?
control rods
Which is or are used in nuclear reactors to absorb neutrons?
control rods
How are nuclear reactors used in nuclear reactors?
Well, as nuclear reactors are nuclear reactors, nuclear reactors are not used inside nuclear reactors.
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.
What type of nuclear reaction is used in modern day nuclear reactors?
Current nuclear reactors rely on nuclear fission as their nuclear reaction.
Which is are used in nuclear reactors to absorb neutrons?
control rods

What element is used in the control rods of nuclear reactors?
One or more elements that strongly absorb neutrons, some are:cadmiumboronhafniumetc.
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 are nuclear reactors used in nuclear reactors?
Well, as nuclear reactors are nuclear reactors, nuclear reactors are not used inside nuclear reactors.
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.
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.
Why use plutonium in nuclear reactors?
Plutonium is used as nuclear fuel for nuclear reactors. Plutonium isotopes (239, 241) are fissionable with thermal neutrons releasing an extremely great quantity of energy.
How heavy water is used to make plutonium from uranium?
Heavy water is used in nuclear reactors as moderator for neutrons.
What substance is used in a nuclear reactor to absorb heat released from the reactor?
In most reactors in the world, water is used to absorb heat released from the reactor.
Why is uranium used in nuclear power production?
Uranium is a radioactive substance. Nuclear power production is carried out by the energy supplied by nuclear reactors. Nuclear reactors control the energy emission by nuclear fission reaction in radioactive substance when bombarded by neutrons.
