A complex transmission electron microscopy (TEM) study of reactor vessel internal (RVI) materials from the baffle-former- barrel assembly from NPP Greifswald (VVER 440), Unit 1 decommissioned after 15 service cycles has been undertaken. All parts of the baffle-former-barrel assembly are made from Ti-stabilized austenitic stainless steel 08Ch18N10T. The materials were exposed to different dose of neutron radiation (2.4 – 11.4 dpa) at temperatures 267 – 398 C depending on position in the core. Three types of radiation induced defects were identified and quantified, namely: Frank dislocation loops, cavities and fine-scaled precipitated particles of Ni-Si rich phases. Black-dot type defects were observed too. Operation conditions were around 300 C that is why defects typical for both low and high regions of irradiation temperatures have observed.
