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.

Irradiation of polymer-based directional dry adhesives with gamma photons has been performed. This irradiation is commensurate with the radiation that an adhesive sample would be exposed to if deployed in a nuclear glove box or other high-radiation environment. Before and after irradiation, samples were tested using a three-axis adhesive testing stage and were analyzed via a scanning electron microscope and a water droplet contact angle analyzer. At doses in excess of 270 kGy, the adhesive performance began to deteriorate, continuing to an overall performance reduction of 55% at a dose of [approximately]500 kGy. Significant changes in the surface energy of the bulk polymer are also indicated by changes in water droplet contact angles, contributing to the adhesion performance loss. Such analyses allow for quantitative statements to be made about the expected performance of these adhesives when deployed in high-radiation environments.
