| Abstract Scope |
MSRs offer many advantages over LWRs. Corrosion is currently a lifetime-limiting challenge for MSRs. Understanding the mechanisms and processes behind the corrosion of structural materials would help to enable better preforming materials. To better understand the behavior of chloride salt systems, model Ni-Cr alloys were exposed to high temperature molten salt in static capsule tests. The chosen salt was a eutectic KCl-MgCl2. Metal alloys were exposed at 700-800 C for up to 2500 hours. De-alloying of Cr was observed as predicted by the thermodynamics of the system. Laser-Induced Breakdown Spectroscopy (LIBS) was used to study exposed samples. LIBS examination showed that during salt exposure salt constituents were deposited on the sample. This work will discuss the results of LIBS on molten chloride salt exposed alloys and develop the utility of LIBS for use in characterizing salt systems. Additionally, the corrosion behavior of the Ni-Cr alloy systems will be presented. |
