摘要
The evaluation and development of materials which can sustain high temperature and intensive neutron irradiation has always been the key issue for the service and safety of nuclear power plants.The in-pile intensive neutron irradiation can produce defects in materials,causing degradation of mechanical properties such as hardening and embrittlement,swelling and accelerated creep rupture.A full understanding of the basic mechanisms underlying the damage production and accumulation is fundamentally important for the optimalization of structure/properties of materials and the proper evaluation of the service lifetime of in-pile key components.
