摘要：

The objective of this study is to find an alloy with excellent corrosion resistance that can be used as a structural material for molten salt reactors (MSRs). For this purpose, a corrosion test is conducted using Fe- and Ni-based alloys with different Mo and Cr contents in a chlorine-based molten salt. The corrosion behaviors of 316L stainless steel (SUS316L), Hastelloy C-276, and Hastelloy N are compared by conducting an accelerated experiment at a temperature higher than the operating temperature of the MSR in the presence of oxygen, moisture, and Cl- ions. SUS316L, which has a low Mo content, exhibits corrosion along the grain boundaries, whereas Hastelloy N, which has a low Cr content, exhibits corrosion on the surface. Hastelloy C-276, which has high Cr and Mo contents, exhibits a lower corrosion depth and weight loss rate compared with the other samples. The results reveal that corrosion in a chloride environment depends on the Cr and Mo contents.
