Recent progresses of varying temperature irradiation experiments on microstructure development in austenitic stainless steels using HFIR are summarized. Each irradiation cycle consisted of 0.05 dpa at lower temperature irradiation (225 and 360°C), followed by 0.45 dpa at higher temperature (340 and 520°C). The specimens were irradiated for a total of 8 irradiation cycles, which resulted in 4 dpa. After the irradiation the TEM samples were electro polished and examined by an electron microscope. The microstructure of the samples irradiated at varying temperature condition (225⁄340°C, 360⁄520°C) were compared with those of same alloys continuously irradiated at 340 and 520°C.
