| Abstract Scope |
Despite FLiBe being the salt most relevant for nuclear applications, studies on FLiBe corrosion remain relatively sparse compared to other commonly studied salts like FLiNaK, primarily due to the inherent challenges of handling FLiBe in a laboratory setting. Many questions remain open, such as whether FLiBe is intrinsically less corrosive than FLiNaK or if the perceived differences are simply due to uncontrolled impurities. To address this, we conducted static FLiBe corrosion tests on Ni-Cr alloys using FLiBe of varying purities. Additionally, LiF was added to FLiBe to modify its fluoroacidity and explore any potential impacts of fluoroacidity on corrosion behavior. Together, these results provide insights into whether FLiBe is genuinely less corrosive than FLiNaK and, if so, whether this can be attributed to differences in fluoroacidity. Practical experiences in handling FLiBe for corrosion testing and sample processing will also be shared. |
