ANS names 2026 Congressional Fellows
Kasper
Hayes
The American Nuclear Society has officially selected two of its members to serve as its 2026 Glenn T. Seaborg Congressional Science and Engineering Fellows. Alyssa Hayes and Benjamin Kasper will help the Society fulfill its strategic goal of enhancing nuclear policy by working in the halls of Congress, either in a congressional member’s personal office or with a committee, starting next January.
“The Congressional Fellowship program has put ANS in a unique position to provide significant technical assistance to Congress on nuclear science, energy, and technology, with great results,” said Congressional Fellowship Special Committee chair Harsh Desai, himself a former Congressional Fellow. “This once-in-a-lifetime professional development opportunity will allow them to learn the art of policymaking and potentially pursue it as part of their careers beyond the fellowship.”

Many concepts for deep underground storage of high level radioactive waste include the use of bentonite (sodium-montmorillonite) as a backfill material surrounding the waste. It is therefore necessary to model the chemical conditions in the system sodiummontmorillonite-granitic groundwater-granitic rock in order to be able to predict the speciation and solubility of actinides and fission products in this environment. In this study, the chemical interactions and the evolution of the chemical composition of the water in such a system have been modeled using the geochemical computer code PHREEQE. The parameters considered are the pH, Eh, and the chemical composition in aqueous solution. Mineral formation has been taken into account in some cases. The speciation and solubility of uranium in this system have also been calculated.
