ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Argonne creates new methodology for digital twins
Hu
Argonne National Laboratory has added a new twist to digital twin technology for research into nuclear energy. According to Rui Hu, a principal nuclear engineer at Argonne, “Our digital twin technology introduces a significant step toward understanding and managing advanced nuclear reactors, enabling us to predict and respond to changes with the required speed and accuracy.”
The research of Hu and his colleagues, “Development of Whole System Digital Twins for Advanced Reactors: Leveraging Graph Neural Networks and SAM Simulations,” was published in the American Nuclear Society journal Nuclear Technology.
Virtual representation: A digital twin technology is an accurate virtual representation of a complex system. It is updated with real-time data from sensors applied to the physical system, such as a nuclear reactor.
Pacific Basin Nuclear Conference 2024 (PBNC)
Mechanical Engineer, University of Washington
Joined Framatome (then ExxonNuclear) in 1982 and have worked in several mechanical, manufacturing, cycle licensing, and neutronics fuel-related engineering roles as well as project management and other commercial roles.
Significant projects have included contributions to development of the BLEU off-spec U reload supply program for DOE/TVA, design of the ATRIUM 10XM and ATRIUM 11 fuel products, reload fuel supply contracting and account management for the NuScale SMR, and serving as communications lead for the Advanced Fuel Management team developing the capability to deliver high burnup LEU+ reloads to US reactor operators.
