Keywords:neutron irradiation, Tensile properties, IASCC initiation, Stainless steels

Based on the database shown in (1), fluence dependence of tensile properties and IASCC initiation were analyzed for PWR conditions. Trend curves of tensile properties and IASCC initiation stress for cold-worked 316 stainless steels were developed as a function of dpa.
