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?
Sounds funny. Maybe they have non-standard definitions of what neutron capture means. If not, put the book in the dustbinIn my book it says that we can prevent neutron loss with neutron capture. Maybe it thinks about neutron-mirrors?
No, a neutron mirror is a material on which neutrons scatter elastically, without being absorbed. In fact, the properties of a neutron mirror are close to those of a moderator.Is neutron mirror that first absorb neutron and then released? After how many minutes it releases the neutron?
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.
