Results of scientific activity:
- Modernization of accelerator ESUVI is carried out, firstly in the world three-beam collinear accelerator is produced which offers the possibility to perform simulation experiments with the account of the effect of transmutants (He, H) and simulate phenomena proceed during irradiation in reactors;
- It is shown that resistance to swelling in steels of ferritic and austenitic classes differ substantially – in ferritic steel hydrogen suppress swelling while in austenitic steel hydrogen induces the substantial increase of swelling. Synergetic effect of joint implantation of helium and hydrogen during irradiation causes the substantial increase of void concentration and of swelling. Swelling in presence of gaseous impurities is higher than in the case of “pure” damaging irradiation. Coefficient of swelling increase varies from 1,25 to 2,5;
- On the base of data obtained under heavy ion irradiation and reactor data function which simulate swelling in steel 18CrNi10T in wide range of doses, temperature and rate dose was determined. Firstly in terms of one model we have described the swelling under reactor and ion irradiation.
