Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

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.
Technical Session|Panel|Sponsored by RPD
Wednesday, November 16, 2022|8:00–9:45AM MST|Sonoran 8
Session Chair:
Friederike Bostelmann (ORNL)
Session Organizer:
Different methods are discussed in the literature to determine approximations for zone-wise inventory in pebble-bed reactors. Various challenges exist including the consideration of a mixture of pebbles at different burnups, different travel paths of the individual pebbles through the core, traveling of the pebbles through zones of different temperatures/flux/powers/spectral conditions, and more. The panel is intended to cover the latest status of these methods, to discuss pros and cons of the different methods, to highlight where experience showed that phenomena need to be considered or that approximations are sufficient.
