Developed device for current stabilizing for controlled thinning for the samples. With the propose for further selection of optimal orientation of samples of the texture of investigated alloys which were researched by EBSD analysis with help of HKL block at electron microscope JSM-7001F. Texture were determined on polished plates taken from investigated material in order to the direction of rolling pip fuel elements. Carried out researches of ion source, determined ion sort and required voltage. Performed preparation of ion of irradiation devise (accelerator ESUVI) for the simulation experiments. Tube samples of alloy E110 and E125 were prepared for further exposure, determined mean grain size, composition of precipitations of second phase (size and concentration). Investigated dislocation density before irradiation. Performed irradiation of samples of alloy E110 within damage dose 20-50 dpa at irradiation temperature 390°C and 550°C. Started electron microscopic of irradiation samples.
