core structural material damage occurrence IASCC preventive maintenance radiation hardening radiation-induced segregation radiation-induced stress relaxation residual stress
This study proposed an evaluation method of damage occurrence of core structural materials by simulation model. Irradiation assisted stress corrosion cracking (IASCC) is one of the damage modes among aged core components. IASCC was thou ght to be caused by material degradation such as losses of workability due to radiation hardening and corrosion resistance due to radiation-induced segregation and residual stress due to welding, then the influence of residual stress on both radiation hardening and radiatio...
