      ANS webinar to focus on low-dose radiation risk

      Join ANS on Thursday, January 21, at noon (ET) for a Q&A with an expert panel as they discuss how to communicate about the risk of low-dose radiation. “Talking About Low-dose Radiation Risk” is a free members-only event that serves as a follow-up to the “Risky Business” President’s Session that took place during the ANS Virtual Winter Meeting last November. The session will take a deeper dive into the many questions generated from the thought-provoking discussion.

      Register now to attend the webinar.

Uranium Chemistry Tutorial

Predictive Chemistry Modeling

February 2, 2021|10:30AM–12:00PM (11:30AM–1:00PM EST)

Meeting AttendeesAvailable to 2020 ANS Virtual Winter Meeting Attendees


This is part nine of a nine-part tutorial series exclusively available to 2020 ANS Winter Meeting attendees.

Understanding the physical constraints and behaviors imposed on a uranium system by chemistry is helpful in establishing necessary criticality safety controls for the process. For single batch operations or for processes that involve only a few chemical reactions that occur effectively instantly, end state chemistry is often sufficient for analysis. However, processes like separations involved multiple stages of continuously occurring chemical reactions and mass transfer that evolve over time. In these cases, predictive chemistry simulation can be a powerful tool in understanding the behavior of the system and imposing appropriate criticality safety controls. The presentation will include an overview of separations methods and equipment, introduction to the mathematics of simulating mass transfer, an overview of available computations programs and their capabilities, and an example process analysis of an industrial scale high enriched uranium purification system.
