Description

Corrosion of the primary circuit materials is one of the problems in high temperature gas-cooled reactors. The effect of gaseous impurities in the helium coolant on the corrosion behavior of Inconel 617 has been studied at 1000/degree/C and atmospheric pressure for 1000 h. The helium gases used contained several impurities; H/sub 2/, H/sub 2/O, CH/sub 4/, CO, and CO/sub 2/. The corrosion behavior of alloying elements (Cr, Mo, Si, C) was affected by the impurity concentration and the extent of corrosion is explained on the basis of oxygen and carbon potentials. 20 refs
