Effect of Tensile Strain on Microstructure of Irradiated Core Internal Material
Original language description
Irradiation Assisted Stress Corrosion Cracking (IASCC) is one of the most significant environmental degradation in the internal components made from austenitic stainless steels (ASS). This mechanism is still not fully understood and there are no suitablecriteria for prediction of the damage during operation. In this work, core basket material 08Ch18N10T austenitic stainless steel acquired from decommissioned NPP Nord / Greifswald Unit 1, VVER 440 - 230 type, operated for 15 years and irradiated to 5.2dpa is studied. This material was tensile tested at two different test temperatures and strain rates in air and at the elevated temperature under water environment. SEM observations of the fracture surface documented ductile fracture of the samples tested in air, but areas of IASCC if tested in water. This paper emphases the microscopic examination results from the mechanically tested samples to determine the underlying IASCC physical damage process.
