Abstract Scope |
In the context of a salt-fueled molten salt reactor (MSR), understanding the chemistry of the lanthanide fission products and their interaction with structural alloys is of importance to be able to adequately describe the corrosion mechanisms that take place in the complex and constantly evolving environment of a MSR. Several of the lanthanide elements are able to form salt-soluble stable chlorides in both the 2+ and 3+ oxidation states, most notably Eu, Sm, and Yb. Europium is of particular interest due to the relatively positive reduction potential of the Eu3+ + e= → Eu2+ half-cell reaction with regards to a number of alloying elements in molten chloride systems. As such, this work investigates the interaction of lanthanide species, primarily Eu3+, and various metallic elements via electronic absorption spectroscopy. This work was supported through the INL Laboratory Directed Research & Development (LDRD) Program under DOE Idaho Operations Office Contract DE-AC07-05ID14517. |
