Corrosion test of HTGR graphite with SiC coating

Chikhray, Y.*; Kulsartov, T.*; Shestakov, V.*; Kenzhina, I.*; Askerbekov, S.*; Sumita, Junya; Ueta, Shohei; Shibata, Taiju; Sakaba, Nariaki; Abdullin, Kh.*; et al.

Application of SiC as corrosion-resistive coating over graphite remains important task for HTGR. This study presents the results of chemical interaction of the SiC gradient coating over the high-density IG-110 graphite with water vapor in the temperature up to 1673 K. The experiments at 100 Pa of water vapor showed that the passive reaction caused to form SiO$$_{2}$$ film on the surface of SiC coating. Active corrosion of SiC in 1Pa of water vapor leads to deposits of various carbon composites on its surface.

The PIE (Post Irradiation Examinations) results of Li$$_{2}$$TiO$$_{3}$$ pebbles added with 5 mol% TiO$$_{2}$$ after the long-term irradiation tests are described in this paper. 96 at% $$^{6}$$Li-enriched Li$$_{2}$$TiO$$_{3}$$ pebbles were prepared as the irradiation specimens and these specimens were irradiated during 223 days at the reactor power of 6 MWt in the WWR-K of NNC-RK. After neutron irradiation, light-colored pebbles became gray-colored due to structure changes which generation of gray-colored inclusions with low density and microhardness. Crystal structure of the pebbles after the irradiation test were changed from the results of X-ray diffraction measurement. The value of maximum permissible load (pebble crash limit) at that was also low. The residual tritium in the pebbles was measured after the irradiation test.
