what elements are used to prevent losing neutrons and what are the ways of preventing losing of neutrons in nuclear power plant and atomic bomb?
The cores of nuclear plants and nuclear weapons (pits) are two different animals.Physicsissuef said:what elements are used to prevent losing neutrons and what are the ways of preventing losing of neutrons in nuclear power plant and atomic bomb?
Physicsissuef said:And how can we prevent losing neutrons with neutron capture?
Physicsissuef said:In my book it says that we can prevent neutron loss with neutron capture. Maybe it thinks about neutron-mirrors?
Physicsissuef said:Is neutron mirror that first absorb neutron and then released? After how many minutes it releases the neutron?
Physicsissuef said:So the only way to prevent loss of neutrons is with neutron scattering, or neutron capture of the next generation of uranium atoms in chain reaction, right?
The best reflector has a high fast removal cross-section with a low absorption cross-section. I believe W-184 has the lowest absorption cross-section of the W isotopes, and is about 30.6% of natural tungsten. One needs to look at ENDF/B data or the Barn book.Delok said:I heard that Tungsten carbide makes a good neutron reflector.
By the way, does anyone knows where i could get more precise data about this material, especially about Neutron reflection rates per mm thickness and so on? I consider using it for a project of mine.

A neutron is a subatomic particle found in the nucleus of an atom. It has a neutral charge and plays a crucial role in the stability and properties of an atom. Losing neutrons can result in an unstable and potentially dangerous atom.
The most commonly used elements for neutron absorption are boron, cadmium, and gadolinium. These elements have a high neutron-capture cross-section, meaning they have a strong tendency to capture neutrons.
Neutron-absorbing elements work by capturing neutrons and forming stable isotopes. This process reduces the number of free neutrons in an atom, making it more stable and less likely to undergo nuclear reactions or decay.
These elements are commonly used in nuclear reactors, where they help control the rate of nuclear reactions and prevent meltdowns. They are also used in radiation shielding to protect against harmful radiation.
While these elements are crucial for nuclear safety, they can also hinder the efficiency of nuclear reactions. In some cases, they may also produce radioactive byproducts. Therefore, careful consideration and control are necessary when using these elements in nuclear applications.
