Abstract Scope |
There is considerable interest in molten salts for several applications including next generation molten salt reactors (MSRs). Several MSR developers have targeted type 316H stainless steel as a near term structural material. Both static capsule and flowing thermal convection loop (TCL) salt (Cl and F) experiments have shown both Fe and Cr dissolution from 316H and indications of Fe mass transfer in TCL experiments. To further study the relative behavior of Fe and Cr, capsule experiments with unalloyed Fe or Cr specimens are being conducted at 550°-800°C for up to 2000 h. Specimen mass loss and salt chemistry are being compared to quantify the dissolution and assess any impact of the capsule material on the dissolution. A more fundamental understanding of 316H molten salt compatibility is needed to develop a predictive model to assist MSR development.
