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.
Meeting Spotlight

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.

Current capsules used at the National Ignition Facility utilize a single-shell design comprised of a single ablator material. Although single-shell designs are currently the standard design, they suffer from several physics disadvantages, such as sensitivity to asymmetries and instabilities. The double shell is a proposed design utilizing a high-Z inner metal shell with a low-Z outer shell that is intended to mitigate the issues associated with typical single-shell designs.
Electroplating is one method that can be utilized to fabricate high-Z metal shells. Au is one particular material that can be electroplated with high density and uniformity. Capsule fill tube assemblies (CFTAs) built from these Au shells have passed all cryogenic leak tests. The shells have a low native surface roughness and are free of voids. Au shells have been successfully fabricated, characterized, and built into CFTAs.
