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
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Neutron Vision at Los Alamos: Exploring the Frontiers of Nuclear Materials Science
In materials science, understanding the unseen—how materials behave internally under real-world conditions—has always been key to developing new materials and accelerating innovative technologies to market. Moreover, the tools that allow us to see into this invisible world of materials have often been game-changers. Among these, neutron imaging stands out as a uniquely powerful method for investigating the internal structure and behavior of materials without having to alter or destroy the sample. By harnessing the unique properties of neutrons, researchers can uncover the hidden behavior of materials, providing insights essential for advancing nuclear materials and technologies.
Sidney Siegel was the President of the American Nuclear Society in 1966. He originally helped organize the American Nuclear Society to promote research and engineering in nuclear technology, and was a charter member of the Society. In addition to serving as President, he also served on the ANS board for many years.
Siegel was born on January 10, 1912. He began his career at Westinghouse Electric Co. in 1938, doing early research on the effect of radiation on solids. In 1943, he became manager of magnetic research at Westinghouse. During World War II, he helped develop torpedo triggering devices and airborne radar systems, and later went to Oak Ridge to work on nuclear reactor development. At Oak Ridge, he conducted research on the first plutonium production reactors for the Manhattan Project. In 1948, he returned to the newly formed Westinghouse Atomic Power Division, where he directed physics-related activities for naval reactor development.
Siegel joined North American Aviation in 1950. Shortly after that, he served as vice president and technical director of the power systems division at Atomics International, where he directed the AEC-sponsored development of sodium- and organic-cooled power reactors to power communications satellites and other space vehicles.
He left there in 1972 to return to Oak Ridge as a deputy associate director for biomedical and environmental sciences. There, he oversaw National Science Foundation-funded research and was also responsible for AEC regulatory work on the preparation of environmental impact statements for proposed nuclear power plants. He left that position in 1975.
In addition to these positions, at various times, he was a lecturer at the University of Pittsburgh, a research associate at the California Institute of Technology, and an American representative to the Atoms for Peace Conference.
Siegel earned bachelor’s degrees in physics and mathematics in 1932, and a doctorate degree in physics in 1936 from Columbia University. He held five patents on solid-state instruments and nuclear power devices and was a fellow of the American Physical Society.
Sidney Siegel passed away on March 16, 2001.
