The Chemical Engineering department invites you to a seminar by Jarrod Gogolski, Senior Engineer, Savannah River National Laboratory:

"Wisdom for Fuel Processing and Nuclear Nonproliferation"

Thursday, April 27, 2023
3:30-4:30 p.m.
Shah Hall 310

Abstract
The mission of the non-proliferation stewardship program (NSP) is to prevent the spread of nuclear weapons while promoting cooperation for the peaceful use of nuclear technology. To achieve this goal, a multi-national laboratory (ANL, INL, PNNL, and SRNL) project, called Athena, was established for stewarding plutonium processing competency. These laboratories are working in tandem to retain the capability to process actinides and leverage that knowledge for other applications. For instance, one application at SRNL is the dissolution and purification of high-assay low enriched uranium recovery (HALEU) as part of the United States High Performance Research Reactor (UHSPRR) goals. Understanding the chemistry, safety hazards, and process scale limitations are factors to consider when designing flowsheets to recover nuclear fuel. Successful application of these flowsheets are achieved by the collaboration of multiple disciplinary groups such as modelers, data science, experimentalists, and theoretical.

Bio
Jarrod Gogolski has primarily studied nuclear fuel dissolution and solvent extraction flowsheets. He is a nuclear engineer by training along with a strong radiochemistry focus, predominantly with Np and Pu separations. He contributes to a variety of projects to support SRNL’s core competencies and missions: formation of solids from dissolved nuclear fuel, recovery of uranium from U-10Mo fuel, PuO2 interactions with fire extinguishants, dissolution of U-Al alloy surrogates in a variety of inorganic acids, metal oxide dissolution in organic liquids, etc. Prior to his radiochemistry work, Gogolski studied chemical and biological engineering with a biomedical focus. By leveraging this expertise, he hopes to explore the interactions between biological systems and actinides.
