Gustavo S. Pereira (MSc candidate)
Gustavo Pereira is a Nuclear Engineering Master’s student at the Georgia Institute of Technology. After receiving his BS in Nuclear Engineering from the University of Illinois at Urbana Champaign, Gustavo joined Exelon’s decommissioning department for a semester long internship. In the fall of 2016, Gustavo started his graduate studies at Georgia Tech.
Gustavo’s academic interests include the expansion of usage of nuclear technologies and solutions to the challenges involving radioactive waste.
Gustavo research is focused on the computational modeling of the sodium cooled Advanced Burner Reactor, a fast reactor design proposed by Argonne National Lab. As part of a group of institutions working on a benchmark for uncertainty analysis in modeling for design, operations and safety analysis of sodium fast reactors, the goal of this research is to model the reactor and it’s fuel cycle using various computational approaches.
Naiki A. Kaffezakis
Naiki is a fifth year undergraduate student pre-enrolled and enrolled in the NE graduate program. Originally from Duluth, Georgia, Naiki has been employed at Georgia Tech as an RA with the Housing Department, media manager with the Honors Program, and TA through School of Mechanical Engineering. Naiki is also involved with the American Nuclear Society student chapter and the Gamma Tau chapter of Psi Upsilon Fraternity.
Naiki has been a part of the CORE group since fall 2016 and has been focused largely on studying the neutronics and thermal hydraulic behavior of a novel fuel assembly design for utilizing thorium-uranium-233 fuel cycles in LWR. The study focuses on finding optimal designs for a thermal breeder reactor with minimum power down rating. Naiki will soon working on promoting the deign further by using system codes to study transients and accidents in the proposed reactor.
