| Abstract |
In order to develop of an advanced spent fuel management process based on the molten salt technology, it is necessary to choose the optimum materials for the process piping and equipment handling molten salt. The corrosion behavior of five Fe-Ni binary alloys at different concentrations of LiCl and LiCl-Li₂O was investigated in the temperature range of 650-850℃. In a molten salt of LiCl, an internal oxidation occurred in all the alloys. The corrosion rate of the alloy showed the parabolic kinetics and it increased with an increase in Fe content in the alloys. In a mixed molten salt of LiCl-Li₂O, an internal oxidation occurred in Fe-rich alloy and a porous scale consisting of LiFeO₂ and Ni was formed in Ni-rich alloy. The corrosion rate increased with an increase in Ni content in the alloys. |
