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.
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.

The Sodium Reactor Experiment
In February 1957, construction was completed on the Sodium Reactor Experiment (SRE), a sodium-cooled, graphite-moderated reactor with an output of 20 MWt. The design of theSRE had begun three years earlier in 1954, and construction started in April 1955. On April 25, 1957, the reactor reached criticality, and the SRE operated until February 1964.
ANS Young Members Group Spotlight on National Labs
July 16, 2020|11:00AM–12:30PM (12:00–1:30PM EDT)
Available to All Users
In the sixth installment of the "Spotlight on National Labs"series, attendees will learn about Lawrence Livermore National Laboratory's history and current ongoing research related to nuclear sciences and engineering.
LLNL was created in 1952 as a “new ideas” laboratory to augment the efforts of Los Alamos in accelerating the U.S.’s hydrogen bomb program. Beginning with the vision of Nobel Prize winner and LLNL namesake E.O. Lawrence, the laboratory established a matrix organization that allows experts in various disciplines to assemble as a team and work together to understand and solve complex problems, a distinguishing feature of LLNL that is still in use today. The unique LLNL environment has allowed for advances in many disparate fields, including high performance computing, laser technology, element discovery, and nuclear weapons science and technology.
