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.

Nominations open for CNTA awards
Citizens for Nuclear Technology Awareness is accepting nominations for its Fred C. Davison Distinguished Scientist Award and its Nuclear Service Award. Nominations for both awards must be submitted by August 1.
The awards will be presented this fall as part of the CNTA’s annual Edward Teller Lecture event.
Ronald Stinson was the 33rd president of the American Nuclear Society (ANS). He joined the Society in 1962 at the same time joining the Operations and Power Division. He was an ANS Fellow, the highest grade of membership of the Society.
Born on April 30, 1931, and raised in Fort Worth, Texas, he graduated from Texas A&M in 1953 with a BS in range management before joining the Army. He and his wife moved to Darmstadt, Germany, where he was stationed. He applied for early release from the service, but was denied because his nuclear training and knowledge were in demand.
After his army commitment was met, he returned to Texas A&M, just as they were just introducing a nuclear program. He earned an MS in nuclear engineering in 1961, becoming one of the first two graduates to hold such a degree.
Stinson moved to Hanford, Washington landing a position working on the big eight reactors of the Hanford Project, which was run by General Electric (GE). Eventually he was transferred to the Vallecitos Lab in the San Francisco East Bay area as manager of nuclear safety. While at Vallecitos he spent much of his time occupied with the Nuclear Regulatory Commission (NRC).
Later he took a promotion as project engineer of Dresden 2 & 3 and Quad Cities Nuclear Plants, and he was later recruited by Sacramento Municipal Utility District (SMUD) in Herald, California to staff and build the Rancho Seco Nuclear Plant.
He left SMUD and became the director of projects at General Atomic (GA), but shortly after GA pulled out of the nuclear industry completely. Stinson and three of his industry colleagues formed a successful consulting business, Manage Analysis Company.
Ronald Calvin Stinson, Jr. passed away on June 27, 2019.
