1、Application 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.

2、Case of starting control rod for primary neutron source reactor
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.
3、Requirements for nuclear grade powderedberyllium oxide in Korea Nuclear Power Research Institute
From the analysis of the impurity index of beryllium oxide, the requirement for its impurities is relatively high, which are difficult to remove impurities, especially boron (B) neutron poison.
4、Research on new nuclear fuel - beryllium oxide coated uranium oxide local and abroad.
