Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

NRC engineers share their expertise at the University of Puerto Rico
Robert Roche-Rivera and Marcos Rolón-Acevedo are licensed professional engineers who work at the U.S. Nuclear Regulatory Commission. They are also alumni of the University of Puerto Rico–Mayagüez (UPRM) and have been sharing their knowledge and experience with students at their alma mater since last year, serving as adjunct professors in the university’s Department of Mechanical Engineering. During the 2023–2024 school year, they each taught two courses: Fundamentals of Nuclear Science and Engineering, and Nuclear Power Plant Engineering.

Several analytical model reduction techniques have been proposed in the literature over the past few decades. We introduce the application of the Schur model reduction method to design a reduced-order, robust controller for the Egyptian Second Testing Research Reactor (ETRR-2). The linear matrix inequality approach is used to design a robust, low-order H state feedback control system and a robust H observer-based controller to control the reactor power. A comparison between the proposed controllers and the actually used conventional proportional-plus-derivative controller is presented based on the simulation of the full-order nonlinear model. Results show the effectiveness of H observer-based state feedback for control of the reactor power at different operation conditions and that it guarantees the system stability.
