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.”

The evolution and formation of a redox front in the near field of a repository for high-level nuclear waste is modeled, considering the effect of a time-dependent source term of the oxidizing species produced by radiolysis of the water entering the canister. The transport of oxidants in the clay surrounding the canister occurs by diffusion. In the rock, the transport of oxidants is modeled as occurring through fractures, with diffusion into the rock matrix. The results show that it is not probable that the redox front will ever move past the bentonite. If it does, the tips of the redox front may move <100 m over a million year period in a channel with a high flow rate.
