Abstract |
In the development of the advanced spent fuel management process based on the molten salt technology, it is essential to choose the optimum material for the process equipment handling molten salt. The corrosion behaviors of 304 S.S., 321 S.S., 316 LN S.S. and Incoloy 800 H in a molten salt of LiCI-Li₂O were investigated in the temperature range of 650-800℃. The oxide scales consisting of Fe₃O₄i FeCr₂O₄and Cr₂O₃ were formed in the 304 S.S., 321 S.S., 316 LN S.S. and Incoloy 800 H regardless of reaction temperature and time. The order of corrosion rate was Incoloy 800 H < 316 LN S.S. < 321 S.S. < 304 S.S.. Incoloy 800 H showed uniform corrosion behavior, whereas 304 S.S., 321 S.S. and 316 LN S.S. showed intergranular corrosion behavior. Incoloy 800 H with high Ni content exhibited the highest corrosion resistance among the examined alloys. (Received February 27, 2004) |
