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.

Report: New York state adding 1 GW of nuclear to fleet
New York Gov. Kathy Hochul has instructed the state’s public electric utility to add at least 1 gigawatt of new nuclear by building a large-scale nuclear plant or a collection of smaller modular reactors, according to the Wall Street Journal.
Dr. Chauncey Starr was the fourth president of the American Nuclear Society (ANS) and was a charter member. He received the Walter H. Zinn Award in 1979 and the Henry D. Smyth Award in 1983 from ANS and was also an ANS Fellow.
Dr. Chauncey Starr was born on April 14, 1912. His first job after completing his doctorate was in 1935 at Harvard University as a research associate in the laboratory, where he worked on the thermal transport properties of metals at high pressure. From Harvard, Chauncey went on to a similar postgraduate position at the MIT Magnet Laboratory, where he worked on cryogenics and magnetic measurements.
In 1942, while at the Bureau of Ships heading a group of engineers working on electronic detection of mines, he was invited to join Ernest Lawrence’s staff at the University of California Radiation Laboratory. Dr. Starr was subsequently transferred to Oak Ridge to serve as Lawrence’s liaison and directed a group of several hundred engineers that made crucial improvements to the yields of the beta calutrons; by the spring of 1945, Oak Ridge had produced enough 235U to arm the Little Boy weapon used against Hiroshima.
After the war, Dr. Starr transferred to Clinton Laboratories at Oak Ridge to participate in the nuclear power reactor design efforts led by Eugene Wigner and Alvin Weinberg. In 1946 he joined North American Aviation, and in 1955 he formed and became president of a new division, Atomics International, to pursue commercialization of the generation of electricity from nuclear power. In collaboration with Walter Zinn at Argonne National Laboratory and the first president of ANS, Chauncey explored the peaceful application of atomic energy to the generation of electricity. In 1966 he left Atomics International to become dean of engineering at UCLA; six years later he founded the Electric Power Research Institute (EPRI). Chauncey also made substantial contributions to the discipline of risk analysis while at UCLA and established an environmental division at EPRI.
For his accomplishments, Dr. Starr received the American Physical Society’s 2000 George E. Pake Prize and numerous other awards and recognition, including honorary degrees, membership in national and international academies, medals from heads of state, and fellow status in professional societies.
Dr. Starr earned an electrical engineering degree from Rensselaer Polytechnic Institute in 1932 and a PhD in physics in 1935.
Dr. Chauncey Starr passed away on April 17, 2007.
