Experimental study of Irradiation Assisted Stress Corrosion Cracking by using Cyclotron Accelerator

The extension of fatigue lifetime under high-energy particle irradiation is considered as the in-situ irradiation effect based on the interaction between the radiation induced defect clusters and moving dislocations. The present experimental study was successful to demonstrate the reduction of the in-situ irradiation effect when hydrogen and helium are sufficiently included in the material. This indicates hydrogen would influence the irradiation assisted stress corrosion cracking (IASCC) for aging light-water-plant materials accumulating substantial amount of helium.
