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
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

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.
The Nuclear PE Exam Preparation Module Program is a video-based preparation tool aimed at those preparing to take the Principles and Practice of Engineering (PE) exam in Nuclear Engineering. The modules are instructional with an abundance of fully worked example problems to emphasize practical learning. A list of Learning Objectives is given at the end of the video, which maps to the NCEES nuclear exam specification.
The module program is organized according to the five specification areas (listed in the downloadable exam specification) that make up the Nuclear PE exam, plus a general area that provides background information that may be applicable to multiple areas:
Notice: This program is under construction. Users may purchase segments of the program one specification area at a time, or users may purchase the full program at a discount.
* Users can find information on Specification Area 5 topics in other study resources.
Every effort has been made to make these videos as time-insensitive as possible. However, certain references (most notably the PE Nuclear Reference Handbook) are living documents that undergo frequent updates. All figure numbers, table numbers, page numbers, etc., are accurate as of the time of production, but please be aware that such references may change over time. If you spot an error, please notify us.
A list of contributors can be found on the project credits page. More resources for prospective exam takers can be found on the Nuclear PE Exam Preparation page.
Prior to purchase, you can view a list of Learning Objectives to see what material is covered in each module.
Upon purchase, the modules are accessed by clicking the titles below to expand the contents menu. Each specification area contains videos on multiple topics. Simply click each title to access the videos within each topic.
