One or more elements that strongly absorb neutrons, some are:
Boron is the most commonly used, cadmium can also be used
The control rods inside a nuclear reactor are made out of Boron.
With control rods made of Cadmium metal, which absorbs neutrons.
Heavy water
We see the use of control rods in a reactor to absorb neutrons. These rods are often made of boron.
Hafnium can be used as a material for control rods in nuclear reactors. This element has a high neutron absorption cross section, and it appears as a big target for neurtons.
To make fuel rods for nuclear reactors
control rods
No, control rods are not a part of the fuel assemblies in nuclear reactors. They are separate "pieces" in the core, and essentially fit in "spaces" between fuel bundles.
Not really. Control rods are used to start up and shut down a nuclear reactor.
Boron is the most commonly used, cadmium can also be used
boron or cadmium control rods.
Control rods are made of high neutron capture materials (e.g, Boron, Cadmium, and Gadolinium)
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.
False, the fission in nuclear reactors is controlled with the movable control rods.
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.
