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.
ANS is committed to advancing careers in the growing nuclear industry by addressing workforce needs through targeted training and certification.
We offer a growing collection of certifications, training courses, and resources, each designed to cater to different specialties. Our programs equip nuclear professionals like you with the tools to expand your knowledge, advance your career, and navigate this unique industry.
Nuclear 101 Course
If you’re transitioning from another industry or looking to expand your technical understanding, Nuclear 101 can get you up-to-speed and give you the foundational knowledge that will help you succeed in the field. The Nuclear 101 course is currently offered in person and will be available on-demand later this year!
Licensing & Regulation Course
This course is for industry professionals with existing nuclear knowledge, especially those in operations, engineering, communications, or oversight. The course examines the unique regulatory practices of the nuclear industry to help nuclear professionals prepare for roles requiring regulatory knowledge.
Certified Nuclear Professional (CNP) Certification
Launching summer of 2025, this certification is an intermediate step between a four-year engineering degree and a Professional Engineer (PE) license. Individuals seeking the CNP credential will need to meet a specific set of eligibility requirements and will then be required to pass a comprehensive exam.
PE Exam Prep Resources
Prepare for the Principles and Practice of Engineering (PE) Examination in the nuclear discipline. ANS offers study resources including a PE Exam Preparation Module Program, the Nuclear PE Exam Study Guide, and the National Council of Examiners for Engineering and Surveying (NCEES) Nuclear PE Sample Exam.
