Investigation of changes of physico-chemical properties of fusion reactor functional materials under influence of high-energy radiation

Duration of the project

05.01.2015. - 30.11.2015.

Countries and institutions involved in the project

University of Latvia
Karlsruhe Institute of Technology
University of Tartu
Kaunas University of Technology

Aim of the project

Investigation of the influence of Li2TiO3 additions on the radiation stability of modified Li4SiO4 pebbles, by analysing the formation and accumulation of radiation-induced defects and radiolysis products.

2) On the basis of the obtained results, recommendations for the development of tritium breeding ceramics can be made and used for further investigations.

3) Ensure long-term cooperation, sharing of knowledge and strengthening of the partnership between Baltic countries and Karlsruhe Institute of Technology (Germany).

4) Further training of the students and PhD students taking part in the project

Main activities of the project

1. Planning of experiments;
2. Preparation and characterization of the samples;
3. The sample irradiation with accelerated electrons;
4. Analysis of samples and comparison with literature data;
5. Preparation of results for the publication at conferences and in a peer reviewed journal;
6. Student training at the summer schools in Germany.

Target group and number of persons involved

The results of this project are interesting for all ITER partners that are working on the development of tritium breeding ceramics (EU, Japan, China, South Korea und India).
