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.

ELI Beamlines is a newly constructed petawatt (PW) laser-based accelerator facility. Its flagship laser has a nominal peak power of 10 PW with a pulse duration of 150 fs. The radiation fields emerging from the laser-target interactions will be pulsed and made of mixed particles of high intensity and energy, thus posing new and daunting challenges compared to conventional radiation protection. The civil engineering constraints of a laser facility bring localized weaknesses to the shielding structures. The ultrashort pulses in conjunction with ultrahigh dose rates strain the capabilities of the commercially available radiation detectors. The complexity of modeling laser-target interactions and the resulting ionizing radiation complicates the radiation protection calculations. This paper is a review of the radiation protection challenges at ELI Beamlines, the adopted solutions, and the practices to minimize the harmful effects of ionizing radiation linked to its activities. Some of the presented solutions may have universal validity, while others are specific to this site and can only serve as an inspiration.
