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.

Explore the world-class nuclear facilities at the U.S. Department of Energy’s Argonne National Laboratory, where we are accelerating nuclear science and technology to drive U.S. prosperity and security.
We will visit one-of-a-kind x-ray and microscopy facilities that let Argonne and visiting scientists characterize nuclear fuels and structural materials, including the Advanced Photon Source (APS), a DOE Office of Science user facility and one of the premier X-ray light sources in the world. The APS has recently undergone a comprehensive upgrade that increased the brightness of its X-ray beams by up to 500 times. Researchers using the upgraded facility are able to probe materials faster and at higher spatial and time resolutions, opening up new frontiers for both science and industry. We will also visit Aurora, a lightning-fast supercomputer that harnesses Artificial Intelligence to simulate advanced nuclear reactors, and some of our experimental facilities where we test the durability and safety of nuclear reactor equipment, such as the Mechanisms Engineering Test Loop (METL) facility.
