摘要
Silicon carbide and silicon carbide matrix composites are widely applied in various fields because of their excellent performance.SiC materials have a lot of advantages such as high melting point,high corrosion resistance,high heat conductivity and low neutron reaction cross section,etc.Therefore,SiC materials is very suitable for advanced nuclear power plant(fusion reactor and fission reactor),accelerator driven sub-critical nuclear power system with high temperature and high flux neutron irradiation environments.Neutron irradiation can cause serious displacement damage in the material,and helium atoms caused by neutron transmulation reaction agglomate into the material to form helium bubbles,which can cause swelling and helium embrittlement.
