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
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.
Workshop

Want to learn more about the MOOSE Framework and how to use it? Join our PSU students and Dr. Joshua Hansel (INL) for this hands-on workshop which will introduce attendees to the Multiphysics Object Oriented Simulation Environment (MOOSE), an open-source finite element framework developed by Idaho National Laboratory (INL) for advanced computational modeling and simulation. The workshop is designed for those with no prior experience using MOOSE. Attendees should bring laptops with MOOSE pre-installed to follow along with hands-on exercises and examples. Installation instructions will be provided prior to the workshop. By the end, you will be able to create simple models with the classes available in MOOSE's library and have basic orientation on creating your own MOOSE-based applications.
Speaker
Joshua Hansel
Dr. Joshua Hansel is a computational scientist at Idaho National Laboratory. He earned his Ph.D. in nuclear engineering at Texas A&M University with his Ph.D. research on stabilization techniques for solving hyperbolic systems of partial differential equations. Since beginning his career at INL, Dr. Hansel has worked on the systems code RELAP-7 and the MOOSE Thermal Hydraulics Module (THM). Currently, he is the lead developer of the MOOSE-based heat pipe application, Sockeye.
