The compatibility of the 316-316 S. S. weldment for CEFR main vessel and the 316-5038 steel weldment for main vessel neck support with 450 ℃ thermal convection sodium and 190 ℃ sodium vapour were investigated foe 3 000 h. The oxygen and carbon content are <25 μg/g and <14 μg/g respectively. The measurement and analysis of the corrosion rate, micro-corrosion morphology, contents of the elements, and the mechanical properties were performed after test. The showed that the compatibility of two weldments with high temperature sodium and sodium vapour are good under these test conditions.
