Project summary

The project purpose is to choose an optimum impurity material assisting in higher radiogenic helium and tritium retention by thin film tritides using Sc, Er and Zr under elevated temperatures and under large current load on the base of experimental study and model concepts.

The works under this project will be continuation of the works earned out under the ISTC project №323.

Complex study by the methods of X-ray structural, mass spectrometric and electron microscopic analysis of Sc, Er and Zr tritides manufactured under the project № 323 and also tritides of newly manufactured alloys of these metals with alloying additions chosen on the base of hypothetical suggestions described in the project № 323 should be continued to better understand the processes taking place in the tritides.

Besides, mechanical properties of the tritides should be studied, their change should be determined with alloying. This will open new possibilities in studying processes taking place in tritides and should allow enhancing choice of the most optimum material of alloying addition.

Recommendations to develop tritides of Sc, Er and Zr alloys having high mechanical properties and also high retention of tritium and radiogenic helium under medium elevated temperature (> 150°C) and large current load should be done using experimental data analysis.

Role of Foreign Collaborators: discussion of work results, scientific consultation, work plans correction, joint research (if necessary).
