Nuclear grade Beryllium Oxide of TaiYang Technology - Beryllium coated uranium nuclear fuel

1Application of high purity beryllium oxide in atomic reactor

 

Profile: Neutron reflector and decelerant (Moderator) of nuclear fuel are usually use BeO, BC or graphite materials.

Beryllium oxide ceramics have lower neutron capture interface and higher neutron deceleration ability. It has smaller capture cross section and larger scattering cross section. While thermal neutron generation, beryllium oxide ceramics are very effective in promoting U235 fission.

 

Application:

The ceramic particles formed by beryllium oxide and uranium oxide can be combined into new nuclear fuel.

The higher the purity of beryllium oxide, the higher the thermal conductivity. Conventional 99% purity of beryllium oxide has a thermal conductivity of 210 (100 degrees), but above 99.95% purity beryllium oxide, its thermal conductivity is 300.
