Abstract

The aim of the proposed project is a development of SiC(f)/SiC composite for the first wall blanket in future fusion reactor. In reactor ITER steel will be used, since in this stage other materials do not meet the requirements yet, however, they are proposed to be achieved till the next stage of development of fusion reactor. In our investigation the objective is a composite based on 3-D SiC textile. Using a technique of electrophoretic infiltration of the textile perform with a slurry of fine SiC powder, we will try to prepare a composite, that will meet the requirements for use in fusion reactor, i.e. appropriate mechanical properties at approximately 1000 °C, impermeability for He and in particular low neutron activation. Since the electrophoretic infiltration, proposed as the technique for the preparation of composites, is not well understood yet and is still under development, a part of the study will be focused in deposition mechanisms and investigations of the key parameters. The main problem that has to be solved is densification at temperatures below 1500 °C. In order to achieve this goal, we will use powders with nano-sized particles as well as alternative additives that form transient melt (eutectic) in the required temperature range and that at the same time, will be significantly less activated that the conventional additives (B, C, Y2O3, Al2O3, AlN). Accordingly, we will study the radioactive behaviour of particular alternative elements and analyse the prepared samples after irradiation in reactor TRIGA. The samples will be also analysed for their structural, mechanical and thermal properties.
