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.

All of the reaction cross sections, angular distributions, energy spectra, and double-differential cross sections are consistently calculated and analyzed for the neutron-induced 46,47,49,50,nat.Ti reactions below 20 MeV. Concurrently, the present work uses the optical model; the unified Hauser-Feshbach theory; the exciton model, which includes the improved Iwamoto-Harada model; and the distorted wave Born approximation theory. Especially, the recoil effect is taken into account in the calculation to keep the energy balance of whole reaction processes. Theoretical calculations are compared with existing experimental data and other evaluated data in ENDF/B-VIII, JENDL-4, and JEFF-3 below 20 MeV. Our theoretical calculated results agree with the experimental data and give a better description than the other evaluations for all reactions.
