| Abstract Scope |
Purification of molten salts prior to being placed in a reactor is essential to extend operational time and efficiency. Metallic Fluorides, Carbon, Sulfur, Oxygen, and Hydrogen all increase corrosion within a reactor. Molten salt fueled reactors have shown promising results in previous corrosion testing when salts are purified. In this work, we will be scaling up fuel salt purification from our previous 500g experiments to 50kg. Additionally, salt will be tested using ICP-MS, OH, CS, and corrosion rate testing after completion of purification utilizing Ar, H2, and HF over the course of a week. In this case, a 3-vessel system will be utilized for thermal purification, full purification, and storage and sampling. Stainless vessels with nickel crucibles will be utilized similarly to past large-scale purifications. Results will inform techniques on future purifications and corrosion rate estimations after the salt is used in new reactors. |
