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.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?
And how can we prevent losing neutrons with neutron capture?
In my book it says that we can prevent neutron loss with neutron capture. Maybe it thinks about neutron-mirrors?
Is neutron mirror that first absorb neutron and then released? After how many minutes it releases the neutron?
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.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.
