boron carbide nuclear

Description

Nuclear Safety Material Nulcear energy is the important clean energy at present. To control the rection speed, control sticks or safety sticks are used to absorb neutrons. That is the crucial point in reactor. Because of rich boron isotope (B*0), boron carbide can be a good subsititute for rare matal alloys, such as Ag-In-Cd、Eu、EuB6 working as the neutrons asorption and shielding material. Nowadays, since the first *0MW high-temperature gas-cooled reactor and fast breeder reactor has been sucessfully applied, boron carbide is used in carbon reactor, heavy water reactor, presssured water reactor, boiling water reactor and so on. What’s more, it can also be used as container in nuclear waste dealing sector. Boron carbide container can last for *0 years. In nuclear shielding, boron carbide can be the second layer to prevent the leaking of neutron and radiation. It also plays an important role in pharmacy and environment protection.
