Abstract Scope |
An understanding of the effects of irradiation on molten salt corrosion morphology is desired as a means to predict corrosion damage in nuclear systems that utilize molten salt. Therefore, a series of molten salt corrosion experiments of Ni-20Cr model alloy in FLiNaK salt under simultaneous proton irradiation were conducted. In agreement with previous observations that show proton irradiation can decelerate intergranular corrosion, preliminary results also reveal that a push from intergranular corrosion to transgranular corrosion occurs under the presence of proton irradiation. These effects are quantified via image analysis of the salt-facing surface and cross-sections, and image segmentation and statistical methods are applied to illustrate the relative changes due to irradiation. In addition to demonstrating that molten salt corrosion could be less damaging under irradiation due to a transition to delocalized transgranular corrosion, this research provides more insight into how to make materials more corrosion resistant in nuclear systems. |
