Date(s) - 02/17/2022
1:55 pm - 2:55 pm



Valmor de Almeida, Ph.D.

Associate Professor
University of Massachusetts Lowell

Dr. Valmor de Almeida is an associate professor in the chemical engineering department (nuclear engineering program) at the University of Massachusetts Lowell. He teaches nuclear chemical engineering courses (available on public domain) that are focused on modeling and simulation. He does computational research in the fuel cycle area including separations and nuclear facility analysis on levels of theory ranging from atomic to continuum.

Before joining UMass Lowell in 2017 he worked at the Oak Ridge National Laboratory as a staff scientist for 18 years carrying out research for various DOE offices including NE, NNSA, ASCR, and BES.

He holds a Ph.D. in chemical engineering from the University of Minnesota, he was a post-doctoral scholar at the University of Minnesota Supercomputer Institute, and a research associate at the University of Minnesota Army High-Performance Computing Research Center. He is a member of the AIChE Nuclear Engineering Division leadership.


This presentation will give an overview of modeling and simulation of nuclear fuel cycle processes of interest to the nuclear energy enterprise.

The nuclear fuel cycle is arguably the most elaborate and complex industrial operation ever invented by humans. It encompasses all possible terrestrial length and time scales, and it provides a unique ride through our technological knowledge. The fuel cycle is a fertile application area for modeling and simulation, and much of the past and future development relies on computational advances.

The theory landscape covered in this presentation is divided into networks, continuum, structured continuum, and atomistic; examples will be highlighted.
