Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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.

The Reactor Physics Division is hosting a panel discussion of the need for and development of a standard to address the initial fuel loading and startup testing of a demonstration first-of-a-kind reactor. Members of this expert panel will include program leaders from actual past reactors. The panel will include commercial reactor physics software developers with NQA-1 software quality experience. The panel will also include regulatory authority on advanced reactor licensing. Modeling software being used to design advanced reactors (fission batter, micro-, SMRs) today is typically validated using pre-existing peer reviewed integral benchmarks. Although benchmarking activities are very rigorous, the propagated uncertainties for as-built reactor systems can still be quite large. Additionally, the advanced reactor systems being considered today frequently have significant differences when compared with the historical reactor systems for which benchmarks are founded. Physics testing during reactor startup is the final opportunity for characterizing data uncertainty before hot full power operation. Therefore, a best practices standard is needed to provide guidance on how to leverage traditional startup procedures with software validation methods.
